hey i really want to buy the prime,
anybody know when the gps will be fixed??
thanks
Sorry to break this to you, but there is no software that can completely fix the primes GPS. The GPS is bad because of the metal back plating on the prime. The back plating reduces reception between the radio signals (Wi-Fi, GPS and Bluetooth) and this is the sole reason why they can't fix it (without losing alot of money). Asus went so far by actually removing the GPS feature off the Asus Transformer Primes website. Sorry to break it to you. Unless you take off the back plate, you probably wont see a dramatic improvement (even after that, its questionable on its strength/quality).
Really....Fairly sure there is never gonna be a real fix. Never used GPS on any of the dozen or so tablets that I've owned.

when metal becomes plastic...
Or when pogo pins become wired.
When you buy a Bluetooth GPS receiver.
Lmao! No ETAs dude

Metal backplate is not the "SOLE" reason. ASUS never admitted to that. They said only a "Possibility" it could be the issue. Now we are seeing other factors could be a reason also. SO UNTIL ASUS RELEASES A STATEMENT saying "yes, we know for a fact the backplate is the only reason" then the actual reason is still up in the air.
I've emailed Asus twice, telling them about my dissatifaction over the GPS issue and after at least one week , have received no reply after the last one.
I understand that GPS is not a big deal to a lot of you and not a complete deal breaker with me either. But the fact of the matter is when I purchased my Prime, GPS was listed as a "feature" and never anywhere was "Limited" or "so-so" GPS capabilities mentioned !
So I receive my Prime, then through forums and my use, I find out the GPS capabilities are very limited and that Asus knows this is a problem, and believe Asus will rectify said issues. So I decide to keep my Prime, past the 14 day BB return period. What happens next ? Instead of fixing the GPS issue, Asus releases a statement saying basically, "Err............well the Prime was never designed to have fully functioning GPS capabilities !" and on top of that, competely removes GPS from the spec sheet !..............WTH?
So my email to Asus asked what they were willing to do for me and others, who purchased their Primes when GPS was listed on the spec sheet as a feature ! Rebate? Discounts off other products? Full refund from Asus ?
So far.....not a peep!
Again, I was past my BB return period , when Asus decided to make GPS a non-issue. Is this really the way Asus wants to treat their customers? And btw, I also own a Notebook and Netbook from Asus and use to believe in their products/customer service. Not so sure about that any longer, when I can't get a reply to an email over a defective product !

It is annoying when people who have no idea how wireless signals work are commenting all over talking about metal casing, pogo pins, etc. Unless you actually have an engineering background, please just stop. You are what is wrong with this country.

A look at the internal set up shows the GPS aerials positioned on either side of the rear camera. The back is shielded by the case but the front is wide open ... right behind the glass trim. But there may be other reasons the GPS is weak despite the fact it is the same GPS that exists in many successful model I am told. My Prime is a bit slow locking on to satellites compared to my Galaxy 10.1. But, even on an overcast night, I locked on and was able to walk my desired route to my location. I felt I had to hold it flat to get a lock but once locked, it seemed to stay locked even after I tucked it under my jacket.

I didn't even know, nor did I ever assume, that any wifi only tablet could get gps that functioned unassisted.. That is my own ignorance apparently so I don't blame Asus - I never thought I'd be able to get gps signal without wifi and since this is a wifi only device I was/am OK with that. (one thing I'm not OK with is that since the last update my gps signal got worse...but since it is changing and getting tweaked with updates I am confident they are working on improving what we do have. I used to be bless to lock onto 10 satellites 5 feet from a window, and now I get nothing. If I reboot sometimes that "fixes" it) )
The Prime does get assisted GPS just like most other tablets without 3g (I said most).

Your only real solution at this point is to buy a GPS puck and pair it with your prime via Bluetooth.

In this case, it's an RF designer you need - but to answer the question, most people disclose their engineering prowess when they post.

Guys i pre-ordered a TFPrime from amazon UK and will be getting it shortly (12-Jan). However after watching a few reviews, etc, I noticed the Wifi / GPS seems really buggy which could be a deal breaker for me. Can anyone share their experiences? Any workaround?

Really?
You can't spit in any direction on this forum without hitting a thread that talks about these issues...why do you need yet another thread? A solution to these, if they are deal breakers for you, is to not buy the Prime.
Yep i guess your post signature leaves it clear... "Asus Transformer Prime (Waiting on a replacement) "
Wifi seems to be fine GPS is wacky but will get fixed
Yes wifi and gps have issues. Be careful about saying anything bad about the Prime in these forums.
A lot of town criers...
The WiFi is working fine, at least with mine anyways. GPS is still broken, but I have faith in ASUS that they'll come up with a fix.
You guys are killing me with this. I was hell bent on purchasing a Prime & Keyboard as soon as stock arrived. I checked all the reviews. I knew about it's pros & it's cons. I was sold. It was just a fluke that I wound up searching about the Prime's GPS accuracy and all of the BS ASUS has been covering up surfaced.
I'm not going to drop nearly $700 on a fancy toy if:
1. WiFi sucks. Especially on a portable device. That simply makes no sense.
2. GPS doesn't work. --I go to UC, so this bad boy needs to be LoJacked. I've seen too many laptops & tablets "walk off and disappear" during lecture.
3. Paying $700 for anything that doesn't have all of it's features intact is a non-starter.
ASUS makes great video cards & motherboards. But they need to get their sh*t together on this device if they plan to stay in tablet game.
Not gonna lie. I got my prime last week thru BB pre order and my GPS and wifi are working great! Not sure why other people $are having issues with this.
Early models did have hardware issues. (especially with wifi)
http://forum.xda-developers.com/showthread.php?t=1394611
This is one reason why you don't want to rush to get one.
A lot of people will state that their wifi and gps is working just fine, but they dont really know any better...
Wifi works but its got a very slow upload and download speed. They may be thinking GPS works but not realize they are using wifi location.
But yes on every unit regardless of what others may say. Wifi does not work as good as it should and GPS doesn't work at all.
And if it is any indication...
TF101 shipped with screen bleed & loose casing defects, to this very day Asus has not bothered to fix the issue.

With so many people reporting problems with GPS and WiFi strength it's become almost a complete certainty that these devices are suffering from some sort of severe design flaw.
I wasn't on the design team for this device, so take anything I say with a grain of salt, but I am quite savvy as an engineer so I'll drop my 2 cents on this issue.
From my standpoint it's appears to be DEFINITELY the aluminum chassis. Aluminum is quite good at reflecting/bouncing RF signals at a focal point (receiver). When crafted correctly, aluminum is great at bouncing rf signals. When used incorrectly, aluminum is great at dispersing and blocking rf signals.
However, as frequency increases, so does penetration. This is most likely why people have been able to notice relatively normal WiFi strengths. Even at wireless-g speeds they're operating at as low as 2.4GHz and up to 5GHz. However CIV GPS operate at around 1.1GHz. In this case, the aluminum shell has turned the GPS unit's "moderate voice" into a "whimper" when it attempts to lock & fix on satellites. -- Think tin foil hats, but for your GPS & WiFi
I also believe ASUS outfitted the Prime with 2 WiFi antennas whereas I believe the GPS only has a single antenna. I won't speak for ASUS's design decisions, but I wouldn't doubt they opted for 2 antennas to deal with the interference from the aluminum casing. However, that's simply my speculation. Why they botched this tablet so badly just to conform to a silly aesthetic design boggles my mind. As Spock would say, "their decisions were highly illogical."

They'd be wise to rethink that choice.
I'm right now wondering if WiFi on my TF101 is OK, because it doesn't get a lock i a room adjacent to the one with the router while laptop in the same place has 3 to 4 bars! So if people say their WiFi and GPS are fine take it with a grain of sand. It's not easy to check them properly in a short time.

An aluminium shell like on the Transformer can only distort the signals a bit but not completely block it (like many are experiencing with GPS). That is probably because of a manufacturing defect and not because of the aluminium shell.
WiFi on this device is fine. I get over 11 mbps speeds on a 15 mbps cable connection.
GPS also locks within a reasonable amount of time when view of sky is unobstructed.

Actually aluminum can do quite a bit to obstruct an RF signal. Depending on thickness, resistance can be quite high. While I somewhat agree it shouldn't be able to block a strong signal, the major function of GPS is to "listen", not to "talk." What I'm trying to say, is it is not producing strong signals, it's trying to receive them, and it's ability to listen is only as good as the ability of such signals to penetrate whatever is obstructing them. In this case, it's Aluminum.. which has quite a high resistance to RF.

YOUR GPS also locks....
If you look at the poll in the GPS Problems thread you'll see that it's about 80 working GPSs to 50 non-working.
Just because yours locks, don't assume everyone else's does. Especially when there is a large amount of evidence to the contrary.

Got those numbers switched. It's around 50 working, and 80 not.
>However, as frequency increases, so does penetration
Higher frequency = shorter wavelength = less penetration. 5GHz wifi has shorter range than 2.4GHz wifi because it can't penetrate as well. Public hot spots only use 2.4GHz. More articulate explanations here. That wifi in the Prime is more functional than GPS is probably because wifi signals have more energy than the weak GPS signal.
I do agree that the Al shell is the main culprit, probably exacerbated by mediocre antenna design. I generally see better wireless performance from phone vendors (Moto, Samsung, HTC) than non-phone vendors (Acer, Asus).
>I'm right now wondering if WiFi on my TF101 is OK
Wifi on most mobiles will be less than that on laptops, because their antenna is usually much smaller and lacks diversity. Size isn't the only determinant in antenna gain, but it's a big determinant. Here are the GPS and wifi antennae on the OG Transformer.
Here is one (of many possible) design for laptop dual diversity antenna
You're right. I got the 2 switched. I distinctly remember writing that on the top of my cheat sheet in Phys. I'm sorry it's 2 am, and I can't brain.
Anyway, as for the signal strength, that's what I was saying earlier. I assume when you take into account considerable distances, even though routers are usually only pumping out around 250ma per antenna, they probably still yield much better signal strength than GPS satellites after the signal has reached the ground.
However aside from ASUS simply not attaching an antenna to GPS mod, it really can only be the aluminum shell creating such resistance. And the fact it seems to affect WiFi as well, although to a lesser degree, means it's most likely not a symptom faulty workmanship on part of the internals.
But as mentioned in other threads, it would be nice if someone tore the aluminum backing off of their brand new Prime to see if it's the real culprit.
I just got mine earlier today. I have to say that I am definitely not among the most unlucky people who receive units with lots of defects. But the issues are enough for me to decide to return it and get refund. Too bad, I was so eagerly anticipating this thing.
Back light bleeding: I know that every LCD product have some back light bleeding more or less. But this one I got is just too obvious, whenever I have some dark background.
WiFi: This is actually the real killer. It is really substandard performance. I think it's nowhere near a decent tablet from the Wifi performance. I initially tested in my room, < 10ft from the router. My MBP gives around DL 20Mbps, -46dBm, while TBP gives less than 12.5Mbps most of the time with about < -55dBm and quite unstable. i can live with it. But i did it in another room, around 20ft with 2 walls in between , TBP drops to < 3.5Mbps immediately. Horrible. that's only 20ft away. A tablet such wifi performance is unacceptable for me. I don't see myself constantly standing within 10ft from a router during my travel or in my campus. that just kills it.
Maybe some people have no problem with WiFi or whatsoever. If you get decent DL speed at >= 25ft with walls in between, you are lucky. I am talking about comparable speed with netbooks or 802.11n tablets, like TF101, not something > 50% lower. I personally think it's a design flaw.
GPS: A lot of people have problem with this one. I have no complain about it. Somehow I am lucky. The one i got was able to lock within about a minuite when i go outdoor. It finds 8 or 9 satellite very quickly and located me with in 50m. I tried gps fix, gps essential, etc. all works. I did a hard reset and switched off wifi during all these. So, I assure you that there are units with good GPS, and not everyone who voted "Yes" had no clue.

I would never return it's amazing
I'll return it if there is no root, Prime no root = Prime is rusty, can't transform to anything
I don't blame you. With faulty wifi this thing is useless. The Prime is clearly not a tablet for use at Uni. If you can't study while eating lunch more than 30 ft away from the nearest AP Extender, it's a piece of crap. Point blank.
Doubt is starting to creep in my mind... i don't know, what do you think...
Wait for my 64 GB grey Prime, which has a ETA of 1/9/2012.
or
Get a 64 GB iPad2 w/ 3G on AT&T.
I did return my Prime because I have BIG issue with screen light leak . I can't believe they did not test there product before packing!! it was cost me $600 with tax + fast shipping. I'll wait for the 64gb and get it for the same price..
two thing I will pass on, GPS (come on, really you need the GPS on Tablet? maybe! I do have phone with me all the time I really believe who ever buying this gadget have smartphone too and it's faster to see where you are going through.. phone.. (again it's personal choice)
3G, I was really happy for not having 3G on my Prime. again where I live, I have wifi (Home, work) and mifi data card all the time I did not need to have extra charges for Data..
my Prime had pretty decent wifi connection.
Mine is getting replaced, but not returned. If I can't root the device, I'll think about returning it if I'm still within the return window.
If I got a wifi defective one, I would probably return it too. There's no point in having a shiny new tablet, if it can't connect to the internet very well.
My Prime gets around 34mbps downstream on speedtest
My Galaxy Note gets around 33mbps downstream on speedtest
My Laptop gets around 37mbps downstream
I'd say the receiver in my Prime is pretty decent.
this is how I'm going to tackle the wireless internet for the Prime.

strange enough that mifi device I bought Wednesday night shows was shipped and handled fast, it was over-nighted and FedEx have already made an attempt to contact me but I'm not at home but at work.
ASUS and the brick and mortar retailers need to learn from Verizon and Radio Shack on how to deliver a product.
In the meantime, I wont see my Prime to Tuesday, and the 32GB microSD and keyboard dock for another 2 weeks after.
I have been testing WiFi quite extensively and I will definitely be returning my current copy. Near the router (< 5 ft), I am getting around 15mbps, which is slower than my Mac Book or iPhone, but it is still acceptable. However; when I go to another room (still less than 20 ft and only one wall in between the router), my speed drops to less than 3mbps (iPhone and Mac Book are still rocking at 20mbps) and uplink drops to less than 100kbps. I also get a lot of connection failures and retries in the next room.
I don't see any use of this unit if I have to use it near to a router all the time. It is a shame that Asus (knowingly!) ruined such a fine hardware. I am in love with my unit, but without a good connectivity, what good is a tablet.
are you guys with your wifi problems the 1st batch or 2nd batch Prime owners posting here?
1st batch are the TFP received prior to 12/28
I'm thinking about exchanging mine. Minor screen bleed, gps is dead, and now my screen is being iffy and starting to pop off on the right side.

Mine is the first batch I think (bought it from BB and arrived on 12/28th).
I have one coming from best buy on tuesday, I am going to keep exchanging it until I get a perfect one.
Although I am guessing by the time I get a perfect one the nexus tablet will be out and I will be selling the prime for that.

I’ve been struggling with why my GPS quit seeing any satellites after the 9.4.2.11 update when I realized something looking at Anand’s teardown:
AnandTech - ASUS Eee Pad Transformer Prime Teardown
Perhaps the antenna connections are weak or have become slightly corroded. Based on his teardown the contacts are spring type “pogopins” which mate with the opposite face. With that thought in mind I decided to try and flex the tablet ever so slightly to clean the contacts. The idea being that the slight flex would cause the pins to scrape the contact surface rubbing a clean(er) spot.
Before the 9.4.2.11 update I had the typical poor performance from the GPS, getting locks but losing them on the move. I had given up on it [GPS] until this update which touted GPS improvements. After updating and wiping I tested the GPS again, but could not see even one satellite after letting it sit, more than once, for over an hour with Wi-Fi on and off.
I must stress I strongly suggest you do not try this on your tablet for fear of damaging it. I take no responsibly for damage to anyone’s tablet and am only reporting my actions.
After this procedure I am able to see several birds indoors, albeit with weak SNR. This has me convinced that part of the problem is related to these contacts, and may serve to explain some of the weak Wi-Fi reports. It may also help illustrate why only some users are seeing issues, and perhaps why some of the returns are functioning better. These contacts may be more robust in some units or possibly be able to be rectified via service.
I do understand there are other factors related to both the GPS and Wi-Fi, but this appears, at least to me, to be part of the bigger picture.
Please note that the amount of flex I’m talking about is next to nothing, enough to see a change in light bleed around the display, I was afraid to go too far.

Hi jhovak,
that sounds very interesting and makes me nervous thinking of manipulating a new device. You are brave!
Do you have some pictures of your action?
Thanks.
Cheers,
René.

You can bypass the pogo pins by connecting a pigtail to the UF.L connector at the chip leadouts, then solder the other end to the antennae's copper pads. It should improve reception.
e.mote,
Looks like you beat me to this I never saw your post, but that's exactly my thoughts. I was able to torque it a bit to get it working again. That maye be what they are doing to get the RMAs reported to work better, "fixed".
motocamp,
Unfortunately I don't have any pictures of the process, but you wouldn't be able to see much, I only deformed the case/screen very slightly. The problem is you may end up popping other solder joints in the process.

I’ve been struggling with why my GPS quit seeing any satellites after the 9.4.2.11 update when I realized something looking at Anand’s teardown:
AnandTech - ASUS Eee Pad Transformer Prime Teardown
Perhaps the antenna connections are weak or have become slightly corroded. Based on his teardown the contacts are spring type “pogopins” which mate with the opposite face. With that thought in mind I decided to try and flex the tablet ever so slightly to clean the contacts. The idea being that the slight flex would cause the pins to scrape the contact surface rubbing a clean(er) spot.

I agree. Makes perfect sense to me.
Everyone has the same aluminum back, so you would expect the same results across the board (barring weather and atmospheric conditions) for all Primes. There has to be another piece to the puzzle of bad GPS performance when some user's report GPS working and getting locks and other user's reports no GPS active with no satellites seen and no locks.
Thanks e.mote for your explanation of the antena contacts. I think you hit the cause of the GPS problem. Hopefully ASUS saw your post and address this prioblem so it does not occur on their the planned 700 series.
Cheers
I forwarded all this info to Gary in a pm just recently. including details, link to that thread e.mote posted in and that teardown showing pogo pins. hopefully he will get it soon and pass info to engineers.

pardon my lack of GPS knowledge but what is considered good or bad when comparing GPS in general? This is my prime outside earlier but there were fluctuations
I am a bit more skeptical about the hardware pins as a sole cause. Reason:
I had pretty decent GPS performance until this last update which totally killed my GPS performance. This suggests to me that there is a firmware/driver type component to at least some people's problems. The same update did correct other people's problems. So perhaps there are some slight differences in the GPS chips that the firmware is not playing nice with or accounting for?
I can confirm this at least partially works. I tried to drive home using GPS test the other day from work and could hardly get a lock especially at high speeds. I saw this and did a number of squeezes aroung the area of the GPS connector and had a significant change.
Drove home with GPS test today and I hardly ever saw it not locked, even going at 70mph, though it would go between 2 and 8 locked sats or so. Halfway through the drive I opened google maps. It took 10-15 seconds to lock, but then I watched my blue arrow follow the road exactly almost the entire way home. It only lost lock when I was stopped under an overpass at a stop light.
To be clear the signal strength is not that of my phone, but at least it's working now.
Have you seen the new evidence found? It was found out that Original Transformer actually uses the soldered type connection E.mote described. I was gonna start a thread but no use as this one is perfect for the new info.
FIRST here is the quote n pics from e.mote of the current Prime type of connection
e.mote said:
From looking at the Prime teardown, your wifi loss may be due to a loose connection. Instead of running a pigtail directly from the chip lead-out to the antenna, the Prime uses spring-loaded pogo pins (1st pic) as intermediate connectors.
Second pic shows the pogo pins for the main wifi and GPS antennae. The spring-loaded pins are pressed against the copper pads of the respective antenna (3rd pic). Suffice it to say, this isn't the most secure way to connect the antennae.
Aside from possible broken or intermittent connection, it also looks like a high-loss connection, and could contribute to attenuated signal reception. My guess is that this may be the main culprit of wifi/GPS woes, with the metal shell being a contributing factor.
The 4th pic below is a U.FL connector that's normally used for antenna pigtails. The lip has an outer overhang for a secure connection.
My guess is that the tablet was bumped and something shifted a bit, breaking the antenna connection.
This is FYI only, as the unit isn't user-serviceable. It does look like a simple fix, but you'd have to open the unit. Edit: You can try smacking the top edge of the tablet a few times and see if it will jar back into place. Worth a try.

Damn, I thought they used pogopins for just the GPS. Now I just found out they use them for the Wifi too! OUCH! Bad idea. A soldered wire would have been %100 much better, but I'm so afraid now to return my tablet to Asus from hearing the horror stories.

Just got PM a lil while ago from Gary n response to the thread n possible pogo pin issue. He said this is something the Engineers are looking very closely at on units being returned to be looked at or repaired. SO things are moving right along. FOUND OUT ALSO my serial number that starts with BCOKA is actually from an early batch that I guess had the older hardware. Engineer or Service person supposed to call within next 48hrs. They are going down the list of people that Gary got serial number, email, and phone number info from. I guess it must be a big list...lmao
SO if I do have to send it in, then they will be adding the new hardware it and hopefully changing those pogo pin connections to soldered ones..lol
Ill know more details once I get their phone call. If I do have to send in, I hope they don't wipe everything as I have around 150-200 apps n games. Things customized n all that. Ill take the new hardware though n hopefully won't go thru the horror stories I've been hearing about on returns. OR ill like it better if they just sent me a brand new tablet with the latest n greatest hardware changes on it then I send mines to them. So it'll give me time to transfer things to new device if need be.
I HAVE AN APP on my Ipad called applist that will list every app you have installed and allow you to email the list to yourself. Does android have anything like this?
Wow. I think we can all agree that Asus dropped the ball in so many areas with the TF201. Who the hell wants to put up with this nonsense???
If only Motorola would build a tablet with a docking clamshell keyboard they could probably take 80% of would be Transformer customers. I'd be first in line.
But what could be the reason ASUS changed to use this pogo pin?
Weight? Cost? ... Sabotage? ... I simly dont understand the engineering thought of it.

It would take alot more than that for Motorola to come up n take Asus customers. The xoom, first HC tablet, was a complete flop. Plus Motorola known for locking their systems down, at least initially. MOTOROLA IS NOT too popular of a brand these days, at least tablet wise.

Good to know BCOKA is from an older batch, have such a unit as well and very crappy GPS and also suffer from mediocre wifi combined with bluetooth degradation.
Also contacted Gary and will keep an eye out for any developments (live in EUrope though).
The majority of Prime users don't root or flash their tablets. Maybe the majority on this site but not the majority of the total users. So I doubt that will dictate the winners in this market.
Secondly, you can't debate that Motorola's hardware prowess is vastly superior to Asus. And definitely good enough not to pull these bone head mistakes that Asus keeps rolling out one after another.
The Xoom wasn't the sexiest by any means but it was solid as a rock functionality wise. Now with the Xyboard and their follow on products improving in the looks department I really do think they could take would-be Transformer customers if they would just offer a keyboard dock.
And if you're wondering the reason I'm not getting a Galaxy tablet, the reason is because their RF electronic know-how is not too much better that Asus's. I gotta say though that at least Samsung had the intelligence not to seal their RF electronics in a Faraday cage. LOL.
I have confirmed that there are very significant variances in the hardware that is causing GPS problems. As I reported in a thread earlier this week, I received a new 64GB model from Amazon a few days ago that had completely dead GPS functionality. Even outside under clear skies, it never picked up even a single satellite. Thankfully, Amazon has amazing customer service and received more stock yesterday. They overnighted me a replacement unit that arrived this morning. Thankfully, since they forward ship replacements I could compare the old and new models side-by-side and decide which one was more broken (I was terrified that the replacement would have dead WiFi, backlight bleed-through, dead-pixels, or one of the other myriad hardware problem that people report. Luckily, its perfect).
The first thing I did (before running ANY firmware updates) was to install the GPS Test app. Within 30 seconds on a cold boot, it had a position fix sitting in the middle of my living room. I then proceeded to install all firmware/ICS updates up to the latest, and it is still completely functional. Granted, the signal-to-noise ratio is not awesome (its no Garmin), but it is definitely a functional GPS. In short, if you get a new TF201 be sure to test the GPS immediately so that you can return it right away and DON'T SETTLE for a broken one.
Here are screenshots from both of my units, good and bad. They were sitting side-by-side in the middle of the first floor of a two-story house. Both units are C1OKAS serial numbers and all firmware revisions are identical at the time of the tests. Bad serial number is 0056xx, good is 0171xx. Perhaps they found a manufacturing problem and fixed it in later batches.

Also, I put in a tech support ticket with Asus for the GPS issue the day I got the TF201 earlier this week and they never bother even replying to me. This company has a support problem (I'm preaching to the choir here...).

It has nothing to do with the metal case, that's for sure. However, one pogo pin contact could be bad while another fully closed and functional. If it works don't flex it!

Well lucky you, you've got a winner!
Mine is C1OKAS 026XXX which would put it after the 0171XX batch (and thus, updated GPS?), but GPS does not get any signal (at least, with Wifi turned on and without the .11 firmware update, which I can't get yet due to the serial number missing issue).
Squeezing does not do anything for GPS or Wifi reception.
Once the .11 update becomes available on the website I will try again.

Hmm, well so much for them working out the manufacturing bugs. I've seen no evidence that any of the firmware updates changed the GPS performance one way or another. If its not working at all out of the box, its not going to work without hardware repair.
Nice comparison. I started a thread to try to track down the differences between the models to see if a common link in GPS performance could be found. Sadly it was sabotaged by some of the brain dead morons on this forum bleating the Asus "aluminum case" line!
Well the evidence is building.
Took mine into the local service centre for a new screen. Nil spares here. So holding onto unit until spares arrive next week & they will repair the GPS at the same time.
Nice to see Amazon on to it.
I have a handful of screen shots from January 14th when I was finally able to get gps signal inside the apartment, never very far from a window, some with wifi on, some with wifi off. I was getting locks of up to 9 satellites. But after the latest update I don't get anything. I can't lock onto to any satellites inside the apartment anymore at all, and I'm only 5 feet away from a window with wifi on. And do you have to calibrate your compass every time you move locations with your Prime? I Mine is aways wrong every time I take it anywhere.
I am totally inclined to believe it is hardware related but don't understand why mine was moderately OK and now crap.

Yeah, its sad some people are so closed minded to other possibilities even when there's evidence to pointing other ways. Plus Asus only said the aluminum case is a possibility, not the only reason. That's where I think some people are stuck on that.
I have two Primes sitting in front of me, as such:
#1: Great screen. The best I've seen yet (and I've had 6), demonstrating some wide variability in screen quality (temperature, colors, text) across units. The temperature on this one is perfect (makes whites the truest), colors are deep and excellent, details pop out, and text is awesome. However, it has one stuck pixel that's only obvious on dark screens and high brightness and the speakers have a TINY bit of vibration at highest volume on some songs. Haptic feedback is the best I've had so far.
However, GPS on it is horrible. After giving it as much as 30 minutes to lock on, the best I've gotten is 5/10 satellites locked. Wifi also seems a bit weaker.
#2: Good screen. Better than the one I'm returning to HH Gregg, which had a horrible yellow cast, terrible colors, and pixellated text. This screen is better, but not as good as #1--a touch more yellow, and not as much detail in complex images. Text is okay but not as good as #1. No stuck pixels, but a little bit of light bleed that's visible on dark screens and high brightness. Audio is fine. Haptic feedback doesn't work.
However, GPS on it is excellent. In about a minute, it locks on to as many as 12/14 satellites. It also locks indoors (within a 5 feet of a glass patio door). Wifi also seems little stronger.
So, this is what is driving me nutty. There's WAY too much hardware variation among these things. I love the damn tablet as well--I can read it outside on my porch in direct SoCal sun, which is very important to me. My OG Transformer was very nice, but I couldn't read it outdoors worth a damn.
So, ASUS, what am I supposed to do, eh? Accept a bit worse screen to have better radio performance, or accept a bit worse wifi and terrible GPS to have the best screen? Or, keep trying to get a "perfect" unit?
I'm honestly tempted to just keep buying and returning units until I get one I'm happy with. Perhaps that's a way to flush defective units out of the system and communicate to ASUS that they have some problems that need fixing. I've been a solid supporter of ASUS, but after having 6 units in my hands that all have some significant issue or another, my support is starting to waver.
My gps worked fine outside prior to the last update. I could pick up around 15 sats and get a lock. Now i get nothing. Asus can blame it on the metal all they want but i know the last update screwed it up for me.

Gps is used by several apps to find location. I have no need to use the tablet as a nav device, but the idea of a component inside my $500 tablet not working really bugs me. Thats the point.

Interesting. I have two BC units with the same hardware revision that have both been fully updated. One gets a very quick lock, one doesn't get a lock unless I let it sit for quite some time, at which point it gets only half the locks of the other one and they're fleeting. At first, I thought it wasn't getting a lock at at (because I hadn't given it enough time), and really it might as well not get any.
So, it must be that some units have hardware issues that the update reveals, while some don't. It can't be the update by itself, because some units work fine with it applied.
I'd love to think that there's something in the last update that caused some systems to lose GPS, because then there'd be hope that this one with the great screen could see its GPS fixed. I'm just not sure of it, however.

Have you tried pinching the "weaker" GPS unit, near the top center (in landscaper mod), near the cameras. There is supposed to be a GPS pogo pin there, and some may have loose connection. There are other threads talking more about the pogo pins.
So going by the op's story, the availability problem is also being caused by all the unsatisfied buyers that are getting immediate replacements for their broken units. Which I am inclined to be ok with. Hopefully, when mine ships on 2/9 (hopefully) it will be a newer problem free model.

I've had success squeezing maybe half an inch off center toward the power button along the top. I have to squeeze very hard though, hard enough that you see the "squishing LCD" type effect, and even then it only works (as in it normally sees no satellites anywhere) for maybe ten minutes and only with an absolutely unobstructed view of the sky (even a couple bare branches will cut the visible satellites in half).
I badly want to replace it, but Amazon will only let me return since the 32g gray is out of stock. My exchange window is until the end of February, so hopefully I don't have to just give up and return it.
This stupid tablet has been so much trouble...
Does the aluminum case affect your WiFi?
Here's a simple test. Run WiFi Analyzer.
1. Hold your Prime with the aluminum back towards the router. Take note of the WiFi Analyzer's meter reading.
2. Hold your Prime with the glass front facing the router. Take note of your reading.
My Prime consistently gets weaker signal with the aluminum back towards the router compared when the glass front is towards the router. (The Prime is about 10dBm weaker signal with the back pointing toward the router, compared to when the front is.)
Try this, what is your difference?
Unfortunately it does affect my WiFi. The range of my router reaches half way down my street. My M18x, iPad 2, Japanese PS Vita and iPhone 4S can reach my router 5 houses down at my friend's place. My TF201 can't even make it out of my living room.

I'm starting to believe that you don't own a Prime. Post some pics along with both boxes and a piece of paper with your handle over the top of your Primes box. Make sure I can see the box. Hurry I don't have all nite.
Here it comes you are about to get owned...

<sigh> Look, I'm not trying to be a horses backside here, but you can't prove jack. The OP, if they are asking for anything, is asking for facts. You keep supplying opinions.
Do the test, or don't post. That's the only proof you have. Or propose a different test.
Your posts in this thread so far are like all the Prime owners who swear their GPS is fine, but when you ask they don't use it and haven't tested it.

He is right though. Proving that the aluminum back interferes with wifi does not disprove that the login pins are an issue with signal strength. Nor would this test provide enough quantitative data to compare potential problems. A single test without equipment or a control (basis for comparison) is not meaningful.
I do not believe it is in dispute that the aluminum back will to some degree interfere with wifi and GPS signal strength. Perhaps a better question is to what extent does the back interfere and to what extent does the pogo pin. Then you can combine the two to better understand where the faults in signal strength lie and why.

Instead of talking about how to word the test. Lets get a standard agreed on and written in stone so we can move on. The sooner we understand what's really happening here the better off we'll be. Believe it or not we are all on the same team with the same common goals. Some people have problems with GPS, I have proven I do not. Even so, it still is a problem that needs to be addressed since it was deviously removed from Asus's website and continues to be printed on the box.
You forgot to mention that he got owned on the "Your posts in this thread so far are like all the Prime owners who swear their GPS is fine" post. and that I was right.

Who are you to question me lol....First off my GPS is PERFECT! It even works from my bedroom. Of course I performed the test!! The OP mentioned his discovery in a different thread. Go troll somewhere else.
I'm starting to believe that you don't own a Prime. Post some pics along with both boxes and a piece of paper with your handle over the top of your Primes box. Make sure I can see the box. Hurry I don't have all nite.
Here it comes you are about to get owned...

What's taking you so long to post a couple of pics proving you have a Prime? What are you doing? Are you out driving around trying to buy a Prime and dock? I see that your still on. Let's get this over with. You have problems with GPS, I have problems with BT/WiFi/Youtube Artifacts. I need you to be on the same team with the same common goal.
Yea, unfortunately the aluminum case is a real pain. If Asus just came out and told us the truth about all this might have been better. They are just going to fix the issues by taking all the hard work that we did and apply it to another version tablet or slider.
Try it, what are your results?
Edited my original post with.....
(The Prime is about 10dBm weaker signal with the back pointing toward the router, compared to when the front is.)
Try this, what is your difference?
OK. I tried this. For me, there is hardly a difference or improvement. With glass facing router I might see a 2-4dbm improvement. Which is nothing really that'll make or break wifi performance. Plus I've noticed also you could sit still with metal back or glass facing router n the signal will strength will fluctuate. So for me, it not affecting my performance. Don't think this is really a good way to tell if back is affecting strength to a noticeable point. Since signal strength is always constantly fluctuating. Even 10dbm difference could be accounted for normal varying in signal strength. 10dbm difference won't hardly affect performance at all really. Need a more controlled test method to where other factors won't influence strength. Just by the way u holding tablet or angle or whatever can make the strength dbm change.
10dbm difference won't hardly affect performance at all really.

Close to the router you are right. But further away, when reading say -60dBm, then another -10dBm is pretty significant for the Prime.
And someone else posted they saw 10 to 15 db difference.
Just curious what others might find. Does turning the back to the router give you a weaker signal, than when the glass is towards the router? By how much?

That is about the differences I see, about 15-20 foot away. Up close, it does have less impact. Seems somewhat exponential, I may start doing proper method tests but so far I just check it when it kicks my curiosity.
