[Q] Is this good for GPS on the Transformer Prime - Asus Eee Pad Transformer Prime

I don't use GPS but with all the talk going on about GPS I thought I would try that GPS test program on my Transformer Prime. Is the attached picture a good response? I'm not sure what SNR means but it appears to have picked up quite a few sats.

For a Prime its pretty good as many people including myself get nothing.
SNR means signal to noise ratio. Which is an indicator for signal quality. In comparison to other devices the SNR is not so good.

That's average, mine is also like this, but it won't ever locate you any closer than that and if you move you lose signal.

Compared to my Galaxy Note...
I got zero's across the board on my prime...for sh*ts and giggles, I decided to compare to my galaxy note.
Note with GPS only accuracy down to about 225-250 feet, SNR on 12-14 satellites ranged from 18-27 or so...
When I add sensors to the mix, accuracy goes to 45 feet... (about same SNR)...
All and all I am continually amazed at the galaxy note... (gps on prime is nice to have for me... my car has nav and clearly the galaxy can do it!)
It seems for a "premium" tablet, they'd have put forth premium components and subsystems like GPS...
on the plus(and unrelated) my wifi has been solid...which is key for me...

Interpreting YOUR numbers
Here is what your pic is telling you:
GPS Status: Green - You have a lock...Your "location (car)" will track you as you move.
Yellow - GPS is active, but you do not have GPS lock and is still searching for satellites
Red - GPS is inactive
Accuracy - 36 ft isn't bad...GPS alone (without AGPS) is going to be about 30 ft. AGPS will improve that number. I have seen numbers as low as 6-10 ft. This also depends on where the "active" sats are...If they are low (at the horizon), the accuracy won't be as good....If your sat's are at about 45 degrees in the sky will give the best reading. As the accuracy gets worse, as you're moving, the map indicator may show you traveling in a median, field, thru houses, etc - so although it shows you, your actual location is off.
Chart - Satellites with SNR below 20 most likely will not lock. Depending on the system (I don't know this one well enough yet) it takes 3-4 above 20 to get a lock (some systems require 5-6 sats)....When most numbers are in the very low 20's, although you have lock....you probably will lose lock at times during your trip....how long is loses lock will vary and depends on when it can pick up some higher numbers...Sometimes, it's only seconds, sometimes it's minutes...when it happens, you won't be tracked. The numbers at the very bottom are the satellite numbers....There are about 32-36 active satellites floating around in space...being able to see 13 means you are seeing pretty much the maximum number available at your location.
Hope this helps your understanding.

[Q] experience: GPS reception in backpack?

I would like to know if anyone has any experience with the quality of the gps reception inside a bakcpack.
I would like to log a trail for about 3 hours. And keeping the HD2 in hand for 3 hours could be a bad idea. I would like to place the HD2 inside a backpack of course as closest to the outside as possible. Is there any chance of still getting any acceptable gps reception to log my trail?
I tried that in a small test. I placed the phone in the pocket of my jeans and logged a small distance. But the trail was a little bit misplaced. Drawed over the google maps map my track was not exactly on the street I walked.
Anyone tried that?
If I can get a lock in my house (bottom floor) then there's a good chance in your back pack, only one way to find out for sure, have a quick walk round your block with your back pack on....
I'd be more worried that the battery will lasts 3 hours..
battery should be no problem, I have an external battery pack (Just Mobile Gum Plus). I just want to make sure that this measurement will work. I have only one try. So I need some tips/hints to maximize the gps reception...
does no one have any experiences in loging trails with this phone?
Should work ok! (Use it in my pocket)
However, you say you have an external battery. This means the device is always getting charged, which could increase the temperature of the battery. So, if you want to keep the device running, you should ensure this heat is removed from it (so, don't put it in your sleeping bag...)
I have used HD2 on long hiking trips and have logged my trails with no problems. Your GPS will get great reception in the outdoors, much better than in cities. A backpack will not affect the GPS signal at all unless you've got it lined with metal!
Well just tried the backpack thing while going to the supermarket. But the result was quite unsatisfying. The gps signal got lost. THe second try was my jeans pocket. Worked neither.
Where did you exactely put your phone in the backpack and in what direction was it faced?
Ok thanks for all the answers. I found the solution for my problem.
I used Navicomputer in combination with S2U2. As soon as I hit the power button of my HD2 (forced standby) the GPS reception was lost. Even with the option ind NaviComputer set prevent standby.
But if I just let the phone switch to standby (leave it unattended) it worked.
Can someone explain that to me?
GPS reception in the backpack was good enough...measurement over 2h worked.
The battery lasted more than 3h of gps tracking without any external power.
Glad to hear you got it working. The GPS probably turns off automatically in standby to save power in the same way that your WiFi connection will automatically disconnect if you leave the phone in standby for long enough. Hope you had a good hike!

Latest Google Maps

Does it crash the Vibrant when using Navigation? Wondering since I haven't gone out to test it myself. Reported Accuracy is also slightly better from what I can tell, shows 7-8 meters in my house (although it's much closer/next to or directly on my house most of the time). Before it would only show 10 meters regardless.

Detailed Wifi research

Hey guys,
as we have so many open questions on Wifi perfomance I decided to do some personal research about it.
I am using the following devices:
ASUS Transformer Prime:
German model, 32GB, gray
Updated to .33 firmware
HTC Desire HD
German one, did not have any Wifi issues to date
Running a custom Sense 3.5 ROM from the based on HTC Sensation XL
I tested the Wifi performance all the time with an app called Speedtest.net
Additonally I used an app called Wifi analyzer to measure the strength of the signal.
My internet connection is a ADSL 32/1 line, this means I can get download speed of 32Mbit/s and upload speeds of 1Mbit/s.
To have a good range of values different distances to the router were tested.
Here are the results:
Directly beneath the router:
TF Prime:
Ping: 15-25
Download: 20-30Mbit/s
Strength: [-40] - [-52] (shows full reception)

Desire HD:
Ping: ~30
Download: 10-15Mbit/s

Thoughts on the data
One thing I did notice was the rather large fluctuation of the Prime's signal. The signal quality changed a lot even when holding the device still.
This happened to the DHD too, but not as extreme.
Another thing is that the signal quality of the Prime is highly influenced by the direction you hold the device. AnandTech said the same in their review and it seems it's true. Again, my DHD doesn't show this behaviour.
You do have to note, that the Wifi on the Prime was always faster compared to the my phone, so I don't see an issue with the speed.
I could not make a real range test yet, but with the .29 firmware my DHD outperformed the Prime on the Wifi range. The DHD connected to networks which weren't seen by the Prime at all.
I am going to test the range with the new .33 update (which seemed to improve Wifi for me) in the next days.
Another quite heavy point is the not about the Wifi speed in general but more about the usage itself.
Coming from a 1 Ghz singlecore phone, everything is way faster on the Prime, especially the market.
Working with the Android market on the Prime is super painless. Everything opens instantly, no long loading times (almost none at all).
On my phone everything takes ages to load (even things only related to Wifi, like the thumbnails)
So compared to my phone "internet" is way faster on the Prime.
Conclusion
In my opinion the Prime's Wifi is perfectly fine. It may suffer a bit under the metal backplate, but ASUS solved this problem with the second Wifi antenna quite good.
The only thing which we should be concerned about is the range. But I do have to say that Wifi range can be easily tweaked via software (yes this is true)
So maybe we can tweak the range after having custom kernels.
If you have any questions, feel free to ask
Nice post. My results weren't nearly as good as yours. My Prime was somewhat on par with my Galaxy Nexus (still a little slower, though), but got killed by my iPad 1. I'm starting to wonder whether the iPad 1 simply has a beast of a WiFi radio and outperforms other mobile devices. I'll try to post detailed test results when I get a chance.
thanks, good test you ran also. I was gonna say the same thing that even though the signal strength went down as you moved further away, it didn't directly affect the speed of it at all. in fact Prime consistently held faster speed rates. I've noticed the very sensitive fluctuations in wifi signal strength in prime also depending on how you hold it. Regardless this has still never affected the experience or speeds seen going into the Prime. I did a similar test against my ipad1 and yielded similar results. no matter the range or if prime showed a lil weaker signal strength, it didn't affect the download and upload speeds. in fact. even with prime having the weaker signal strength, it still pulled the faster speeds.
glad to hear we will be able to tweak the range through software. also having the dual antennaes could give us a major advantage over the other devices in the end as far as range goes. I did try your one simple test before you mentioned on the wifi switching antennaes things. as I covered both up signal dropped. then covered only one and then the other and so on. so the switching of wifi antennaes does seem to work pretty well. Custom kernels could use all of this to the advantage of Prime.

I think it may of been you I told of how my ipad1 test comparison was the opposite. that the Prime showed dramatic increase in wifi speeds and was on par with the range, for the most part. what I can say is that Ipad signal strength seemed more stable while Prime was sensitive and fluctuated. regardless though even with a slightly lower signal strength the prime wasn't affected in terms of speed. it still in fact pulled substantial faster speeds than my ipad1 regardless of signal strength. strange but true. you would think with lower signal strength it would affect speeds but it didn't with the Prime.

Yep, I did that too, works wonderfully.
In kernel sources you can adjust up to what reception levels Wifis are still displayed as connectable. We had that problem with a Desire HD update were HTC screwed something so it connected only to way stronger Wifi than before.
Kernel devs fixed this
Issues
I did hear about while reading an article that the prime had issues with its productions models.
one reviewer had 2 before his 3rd finally worked. However im looking forward to testing this beast out come the 12th!
Thanks for making my decision easier
I've done the same test, however with my prime
I get about 20 mbps in the same room as the router
5 mbps one room over
and 2 - 3 mbps max three rooms over, I also often get disconnects in this room.
I can deal with slightly less range, but the speed dropoff was killing me.
Now that I know my unit is obviously defective, I can exchange it for a new unit
If I can get a good unit with results like that I will be satisfied.
When I did some tests on mine, router in living room, Prime on second floor at the furthest point, so probably like 50 feet goign through the floor and a bunch of walls, I was transferring data TO the Prime via FTP at about 2.7MB/sec (Megabytes) That was on .29

I'm having the exact same experience as you. However, I'm not so sure that the Prime is "obviously defective" if you have these types of issues. The last thing I want to do is return my brand new device and wait to find a new one, or RMA it and wait to receive a new one, and then still have the same problem.
I wish Asus would say something if they did in fact make a Wifi change since their earliest models. If they'd confirm this, I'd be more than happy to exchange my Prime for another one, but I can't see going through the whole exchange process with no guarantee that I'll see any type of improvement.
EDIT: It appears that those of us noticing issues with the WiFi range don't have defective units. Check out this review, which discussed the speed comparison between a confirmed defective unit and a non-defective one:
http://www.anandtech.com/show/5178/an-update-on-transformer-prime-battery-life-wifi-issues
Basically, the defective unit wouldn't pull more than 2 Mbps anywhere. It wasn't strictly a range issue - the thing just was capped at about 2 Mbps. The non-defective unit fixed this cap of 2 Mbps, but still had issues where the device downloaded slower than other devices at a further distance from the router (the example the reviewer used was that his original Transformer would get 34-37 Mbps, while the non-defective Prime would get 10-16 Mbps in the same location).
So for those of you considering exchanging your Prime because of poor WiFi range, I think you'll be disappointed to have the same issue with your replacement.

While I agree that I can't prove it beyond reasonable doubt, the reality is I live in a fairly small apartment, it can't be more than 30 feet, admittedly through a few walls from my router to my bedroom, every other wireless-n device I get still gets near 20mbps in my bedroom, and other people are reporting much better results and I can't imagine they are in a house or apartment meaningfully smaller than mine.
So the performance is not acceptable when I paid for a premium android tablet, I'll exchange it and hope it gets better, if it doesn't I'll just return it.
A tablet is useless without wifi, I'm willing to accept a little bit of range problems, but Wireless-N speeds at 30 feet max like I'm getting is just not acceptable.
In that article he never mentions still experiencing the sharp drop offs I'm experiencing, and theirs nothing saying that everyone who has wifi issues has exactly the same issue, his first unit was probably preproduction, which would likely have different issues than the production models
Maybe it will fix it maybe it won't but it won't hurt trying. I'd rather take a chance and try to get a better unit.

Great review Diamondback! This is almost identical to the results I posted about my Prime WiFi. I had an "early model" in the beginning of December that I traded in for the first shipment at Gamestop and most of the WiFi issues seem fixed. Signal strength fluctuates quite a bit more than my Kindle Fire or iPad. Speeds are about the same or better 90% of the time.
With all the complaints out there about WiFi, I don't know if we were just lucky to get good units or if the complaints are a bit overblown.

Keep in mind there are more variables in your tests than simply signal strength and distance. Have you looked at the channel your router is using? These days - especially in apartments - there is a LOT of traffic on the wireless spectrum. WiFi Analyzer can help you narrow the list of channels to use and through trial and error I was able to pick a channel that improved my performance at a distance by quite a bit. But I live in a high-rise condo so you may not have the same types of issues.

This is a good point, as I also live in an apartment complex with a decent amount of wireless traffic.
However, if you have 4 different devices at the same location, and 3 of them pull comparable speeds while one of them (e.g., the Prime) pulls much lesser speeds, doesn't that suggest the problem is more with the Prime than with your network settings?
Also, when traveling, one doesn't have the ability to tweak network settings, so the Prime's weak WiFi is more problematic in this type of situation.
Sorry if I come off as *****ing here. I love my Prime and I'll be keeping it despite its WiFi shortcomings, but it obviously does irk me a little bit.
A little tip for all of you with issues. What about trying another Wifi channel?
"Wifi Analyzer" has a great feature where it shows you which channels are crowded and which are mostly free.
This way you can find a channel with the least interferecens by other Wifis.
Have a look here: http://forum.xda-developers.com/showthread.php?t=1420886&highlight=wifi&page=3
Also take into consideration, that you compare the brand new device and first of a new kind of devices, with others that already had 10-15 updates.
Also make sure you are testing in an "clean" or at least not changing environment. So if on of your neighbours is doing a large file transfer on an neighboring channel during your tests you will see a massive impact on your tansfer-rates.
So far i can say the general WIFI is stable and fast, only the coverage seems to be a bit low compared to other devices. But hey it is an 11n capable device that could in theory be fine tuned to very good reception depending on what features are already used and what not. But i was not able to get any info on what antennas are inside, where they are, what chip is used etc. Any infos on that?
this is all good and dandy now go test this again with Bluetooth enabled and a headset or bt headphone paired.

I always use wifi analyzer when setting up my network and it's configured for the clearest channel available, I know that part of my situation isn't ideal, I can see 7 aps from my laptop right now, but most are on channel one, two on channel 6 (one that's the apartment right underneath me) and I'm on channel 11 which only has one other ap and it's very weak.
Like you said I think the fact that other devices gets better speeds points clearly to the problem being with the primes Wifi, maybe it doesn't handle interference as well as other wifi devices and others have less interference in their tests, which could explain the higher speeds they get.
<B>Update:</B>
Well I took a $14 gamble ( the cost of shipment back to newegg ) for a RMA replacement, hopefully the next unit will work better, I'll put up an update when I get it back, assuming they can get a replacement and don't just refund my money.
At least if I get it back and get the same performance I'll know for sure it's a limitation of the device and not my particular device being defective, I'm a little OCD so that would drive me nuts not knowing as it has the past week lol.
I think another thing everyone should be testing is wifi stability, not just raw speed at a given moment. open wifi analyzer on the prime and another device, go to the signal meter, and compare how long each device can hold onto the signal. In a few videos I've seen where people do this the other device is very stable, but several times a minute the prime's needle goes momentarily to 0, even though they started at similar levels.

GPS performance?

Hey guys, do we have any real world tests of GPS fix time / accuracy??
Sent from my GT-I9100 using XDA
Havent seen any but this is a good question to ask "vickytoria" to test for us in her video thread.

Accuracy is almost 30 feet which is 10 meters all the time which is a good sign.
Note that the device was tested in aero plane mode so no Agps which means a real good sign.

it's like the s2 singing that song since it's thinking it's going to be replaced by the new s3.
hehe
as this device has glonass along with gps it should be damn fast.
nice video posted above and some extra news is the mobile needs 20 seconds to boot... i thought there would be some improvements here
A very good post and nice video, i was actually worried about this.
He says that even when he is in buildings and houses the GPS managed to lock onto a satellite.

HTC One X
Lock speed : 2 - 5 Seconds
Accuracy : 5 feet (<2 meters) [ Consistently getting 5 - 15 feet ]
Number of satellites lock : 2 - 10 Max [But never looses connection]
Location : Singapore
Has Only GPS
Galaxy Note
Lock speed : 2 - 5 Seconds
Accuracy : 30 feet (+-10 meters) [ Consistently getting 24 - 35 feet ]
Number of satellites lock : 8 - 17 Max [But never looses connection]
Location : Singapore
Has Both GPS and Glonass
Galaxy S3
Refer above video
I expect SGS3 will be in range with Galaxy Note with accuracy of < 30 meters and instant lock to the satellites as shown in the video.
Point to note here is, just because the devices locks to more no. of satellites doesn't mean the accuracy is going to be good. I have seen it and experienced it but do not have an explanation for it.
I am very much interested in SGS3 wrt the GPS for Using SYGIC ! especially with the original Samsung car mount.

he already loaded the location with the gps on the s3
he didnt on the s2 and disable wifi when he starts
if you look at 5min, where the S3 is probably still hot starting in gmaps, after 2-3s he quits gmaps and the GPS lock icon is still blinking (= no lock), so much for "instant lock"
the S2 locks rather fast (even if most likely slower) with hot fix outdoors in similar conditions
so sure, glonass+gps is probably faster, but, the comparison video is pretty poorly made.

I agree with you. That was a bad comparison and doesn't give the S2 justice.
I took a screenshot of my S2, beeing indoors, and as you can see I got a 3 sec. fix. It varies between 3-10 seconds.
At the Galaxy S3 Presentation Show I read in the specs the s3 supports glonass too. I love glonass on my xperia play and miss it so much on my EVO 3D.

Do you have any problems with GPS-apps in Xperia?
Theoretically, with GPS and Glonass, you should get 24 satellites in view with both, 12 over the horizon with GPS and 12 with Glonass. I'm not sure if all GPS-apps are able to show 24 sats?

HTC One X
Lock speed : 2 - 5 Seconds
Accuracy : 5 feet (<2 meters) [ Consistently getting 5 - 15 feet ]
Number of satellites lock : 2 - 10 Max [But never looses connection]
Location : Singapore
Has Only GPS
Galaxy Note
Lock speed : 2 - 5 Seconds
Accuracy : 30 feet (+-10 meters) [ Consistently getting 24 - 35 feet ]
Number of satellites lock : 8 - 17 Max [But never looses connection]
Location : Singapore
Has Both GPS and Glonass
Galaxy S3
Refer above video
I expect SGS3 will be in range with Galaxy Note with accuracy of < 30 meters and instant lock to the satellites as shown in the video.
Point to note here is, just because the devices locks to more no. of satellites doesn't mean the accuracy is going to be good. I have seen it and experienced it but do not have an explanation for it.
I am very much interested in SGS3 wrt the GPS for Using SYGIC ! especially with the original Samsung car mount.

I own a Note and One X and the Note's GPS performance is much better than the One X's. The One X's is fine for navigation purposes, but less so for sportstracking and so forth. It's lock speed is not 2-5 seconds as you suggest (it's generally 5-10s and occasionally a little longer, which is fine, but not as good as you suggest), and neither does it never lose position.

thanks for clearing that up.
liars go to hell.
Who cares about the lock time, accuracy is more important...
I had HTC One X for 1.5 month and GPS was the best I've ever seen. I use Sportypal to track my workouts and not only it almost always showed my track on the road and not over houses, but it also was almost perfectly smooth with little zig-zagging:
SG3 though, I had only few days and first experience is not good, actually it's terrible. It was loosing connection all the time on clear day and the result - the track was all over the place:
This phone had the best GPS I've ever seen on any device, and I've had many phones. It connects under 2 seconds and finds more than 10 sattelites every time, even without a data connection. I'm very impressed by it.

[Q] help - running apps

hi, I noticed that when I activate any running apps(runkeeper, mapmyrun etc) with gps and data(3g) , even though im stationery...the app icons(tat represent me) would move around on its own... clocking distance.......is there anything wrong with my omate? what can I do...pls advice.....

The TS GPS can be quite good. It is better than my Garmin ForeRunner 305 (still one of the best GPS receivers) 4 out of 5 GPS points or so. Occasionally though, there is a point far off other times the accuracy just decreases some minutes.
With EPO (use MT GPS app) and A-GPS it locks very fast too.
There is a HW problem though, the GPS antenna can snap. But then you will not get a lock at all.
It is normal that GPS units shows speed when still, especially with bad coverage, you have to compare with a known reference GPS to say if the TS is bad/good
There is minimal difference for apps (most only have some smoothing differences)
I believe IpBike is the best running app.

It is normal, if you have started timing.
Due to accurracy, the GPS position is not exactly the same everytime, it is like throwing darts.
The GPS can be good.
