I've noticed that whenever I'm downloading one of the fine ROMs we have for our phone over my data connection, I can get it done more than twice as fast if I set my phone vertically (like in a cup or resting against something) than if I were to either hold it vertically or set it horizontally in a desk.
I'm pretty sure this is just a limitation of how cell phone technology works, but if you're needing to download something quickly you might want to give this a shot.
I'm able to reach roughly 1.2mb/s on the cell tower near my home while doing this. The pic above's just an example, it's difficult to take a screenshot when your phone is resting against a monitor (This speed is twice as fast as my home DSL connection which is capped at 150gb/mo, also through AT&T -_-) If I were to just hold the phone or simply set it on my desk these speeds plummet to around 200-300kb/s, max.
One theory I have though is we have a ton of pine trees in our area, so this may be disrupting the signal and polarizing it vertically, but don't quote me on this as I'm no where near educated enough to make this call.
[size=-5]get it? no? okay I'll leave now.[/size]
Edit: Oh, I've got to note that I'm in the middle of no where when it comes to a cell signal, so getting better download speeds than the only high-speed internet company available at my house is rather awesome. Sprint doesn't get a signal out here, so my brother's using an Airvana system our or DSL making it even slower.
You want fast? Get a Wilson amp for your house.
Yeah, that makes sense - polarization can make quite a big difference. What's best varies from location to location though.
I have been tethering for 5 years (90% which was my main internet) and I found holding it does make a difference.
Don't have a scientific explanation, but I know for a fact it does.
Not sure about the way I point it, never tried that but usually moving it from my stomach to my hand (laying in bed) will double the speeds...sounds crazy I know.
Reminds me of the issues with FM radio Reception.
Every time you touch the antennae, the station came in great.
Let the antennae go and it's back to bad reception.
Kinda defeats the whole adjustment procedure.
Or holding the car Key remote beneath your chin to get more "door lock" distance.
Inquiring minds want to know.
Hah that's crazy you mention the car key thing...someone at work was talking about that today. First time I've heard of it.

Yup - Your body WILL affect the pattern of any nearby antennas! Sometimes for the better, sometimes worse.
Usually worse at cell phone frequencies, sometimes for the better for FM (lower frequency, wavelength longer than humans are tall.)

I learned something new today, thanks.
Ah, the joys of inductive coupling. Somewhat related to sympathetic resonance (aka sympathetic vibrations).
I will hold my phone in any which manner I please TYVM

Just the idea that you understand RF polarization exists puts you beyond the typical user.
On the other hand, now I'm going nuts with google trying to figure out what polarity GSM signals typically use. My first guess would be vertical, but its only a guess...

Never posted here and perhaps this post isn't necessary but felt compelled. I preordered from Amazon on 11/22 and was salivating for a month until the GPS issues started to be reported. The salivating turned to apprehension. On 1/3 I received the Prime and it is indeed gorgeous. Sadly I'm suffering the same problems as most. No need to beat a dead horse. The GPS issue I can stomach since I have a bluetooth Garmin that works fine with the Prime. However the poor GPS performance is extremely disappointing. Simply transferring files from my laptop to the Prime over wi-fi was much slower that transferring between other devices in my home. In fact so far I'd say it's unusable in that regard. I should add that I'm sitting less than 3 feet from my router when transferring.
Perhaps my expectations were too high but with the keyboard my plan was that this device would replace my laptop for all but the most rigorous tasks. That's not going to happen and now I'm not even sure I'm going to order the keyboard.
BTW BT is weak as well. If all of these issues are indeed due to the aluminum case it's just unbelievable to me that a company could screw up this bad. I'm hopeful that someone comes up with something even if it's just providing instruction on how/where to take a drill to the darn thing. But my expectations aren probably too high on this front too.
In short unless someone has disposable income I'd advise they steer clear and wait for a better offering. I'll likely keep mine until something better appears then I'll be putting it on Ebay.
That's not review, you are beating the dead horse....

Well I guess you're right. A mod can remove and my feelings won't get hurt.
I guess I just wanted to get my shots in on that horse.
ride the dead horse.
a drill won't fix it. you need to point the screen at the router.
the entire foundation of the tablet is built into the aluminum case. everything is screwed into it.
the antennas are on either side of the front-facing camera. want better reception, point the tablet screen in the direction of your router or BT tether
How to Bluetooth tether?

Put phone in one can and tablet in the other (use bigger can for tablet)

Hi Guys,
I got the prime a couple days ago and noticed that there is a single pin that looks to be pushed back from the edge of the connector. Looking at the back of the tablet, it's the second pin from the right.
It's probably not making contact with the 40 pin cable... I have only plugged this tablet in a handful of times.

Here's the image of the connector...
I checked mine and as far as I can tell I dont have one pin down like that.
Do you have any problems charging or connecting to your pc?
The tablet charges and connects. I don't know what functionality the pin provides. It could just be a duplicate GND or PWR pin, which will reduce the reliability over time as I'm sure they've allocated pins for the maximum charging current. Over time the other pins will increase in contact resistance and start heating up above the designed limit.... It's one of a few issues I'm having, so it will be going back to the store. Thanks for checking the connector, I wasn't able to find a high quality picture to verify.
Pete
Yah fair enough, not worth taking a chance.
Good catch really. How did you even come to be looking at the connector so closely to begin with if you didn't have any connection problems. Lol I had to look pretty dang closely even knowing what to look for to check if mine was the same.
Electrical Engineering has given me the passion of electronics. I'm thorough in my 'first article inspections'.
Essentially I'm interested in the choices others make during design. I returned the tablet and will wait for similar product in the marketplace or a future batch of primes. Until then it's back to the laptop; CES2012 should provide some insight.
Good luck then! It definitely looks like you are going to have a lot of cool choices from all the talk from CES
Mine are all in a row, although in a slightly staggered/raised pattern, sort of like ---> .,.,.,.,
Went to plug mine in to charge tonight and nothing happened. I looked at the pins and they are all bent to hell. Can't connect at all now. Once or twice I will get it to plug in and the screen will turn on, but not charge.
Super pissed as I am traveling tomorrow and was psyched to have this with me.
As I write I am trying to straighten the pins with a safety pin. I touched something wrong as it vibrated and reboot.
GOD DAMN IT!
Any suggestions here?
________________________
Edit:
So toast. There are broken pins in there and everything. WTF? I just uploaded a bunch of music on there last night for the trip tomorrow. I come home to charge and...total crap.
It's too late for Best Buy to take it back, I think I will have to use my credit card protection (Amex) to return this. Even if I sent it in to Asus for repair under warranty, this happened in, what, 3 weeks of light use?
So disappointed.
any updates on what happened with your prime...it appears i'm in the same boat with the bent/broken connector pins...just got my RMA and scared after reading all the stories on here but looks like i have no other choice
I just noticed my connected is a little broken, half the plastic piece is missing. i don't know if it came like that or i broke it. i've been careful with it so who knows. only had it about 3 weeks. it still functions properly, charges/syncs/connects to dock. i'm aprehensive about sending it int o get fixed.
Ok for starters i don't really care if my Prime's GPS works or not or even came with one. I have my smart phone for that. But i understand there are some people out there that are upset because it was shipped with a GPS in the specs and it should work.& not have to put tinfoil or be in some sort of force field or perfect condition to work. I just picked up "another" Prime today, i got the Prime fever lol. Anyway here is two pictures one of me driving at around 45mph and another while i was filling up for gas at a stand still. Both off wifi obviously. I only tested this once so far and it is cloudy and raining today. So i figured this would be a great time to test being its not "sunny and clear" skys Now sorry for the blurry pics its very hard to take a picture with a 5.3" Galaxy Note phone while holding a Prime & hanging onto the wheel lol. Let alone not safe
I dunno if these results are considered good or acceptable compared to other devices. But this is what i got on 1 test run, on a rainy day mind you. That is for the GPS guru's to figure out from my pictures. And in reality i just wanted to have some fun testing.
Also... I am on 9.4.2.14 FW & 9.13 GPS
Here is a picture of me while i was at a stand still filling at the gas station

How come the speed window says 0?
72' accuracy while driving is crap, but at least you had a lock.
Let's not let this thread drift from the fix issue.
I just received my new asus prime today, 30 minutes before heading to airport. Needless to say it is dead, so I'll report back to see of quality conrtrol has improved , on the appropriate thread.

Totally agree. Good luck.
Okay so I work in a water restoration company and figured why not test the accuracy of the S4 with the tools we use in the field. Well with any thermohydrometer's they take a little time to get an accurate reading for a few reasons and depending on where it's stored. Our meters are stored in a water proof box and of course the phone is in your pocket. Both of which will affect the readings for the first 1-5 minutes.
Attached are the readings I got within 3 minutes of each other and they are very close to each other to consider the S4's readings to be very accurate. The readings were still getting closer to each other but they were slowing down. So I'd say it's safe to say you can trust the readings the only thing yo remember is that when you've got the phone in your pocket and not off the table you have to let it sit a little if it's been sitting then kick it on and the readings are already correct.
If you have any questions feel free to ask. No I didn't adjust any settings on my phone they were correct out of the box and leaving the screen on and heat from screen and battery didn't bother the readings at all. Holding your phone can if your hand is near the bottom near the sensor.

Hi guys,
Using an audio analyzer you can always see but obviously not hear these proportionately spaced audio spikes coming from the V60. It can also be measured using another device by bringing it closer to the V60. I'm attaching a couple of screenshots that show what I mean.
I've read that the second screen is wireless and about wireless payment or charging functions that could be playing a part in this.. I'm really not sure so I decided to ask if anyone else sees the same thing. It's the first time I've encountered this on any device so I'm pretty curious.

What format is the output ie bt, 24 bit toshlink?
With stereo speakers in a room you could hear that. With closed drivers ie headphones no.

This is the V60 internal mic picking it up. Default Android output/input (48000hz 24bit, I assume). I just open any free RTA analyzer (with good enough resolution) , and it picks it up. It's always on when the screen is on. it can be seen and measured with any device able to pick up above 18Khz (I used another iphone 7 with the built in mic). When the screen goes of it's gone, when only the fingerprint scanner is visible on the V60, theres only one spike visible around 18500hz. When the whole screen is on, I can see a mountain of spikes around 18500hz, evenly spaced. My guesses are it's either connected to the fingerprint scanner, wireless second display, wireless pay or charge functions. My LG V60 is the only device I've witnessed this with and Ive only measured this one device so I'm not sure if there's something wrong with mine or all V60s behave this way. Either way its interesting . The app in the photos is Sound Spectrum Pro, I like it because it has extremely wide resolution and you can zoom in on any frequency range.
Try disabling the fingerprint scanner...
I just disabled the fingerprint scanner and it's still showing. I made a video and I'll try attaching it here.
Youtube LG v60 18500hz evenly spaced sound spikes
Maybe from the power regulation? External interference? There's no negative portion to that wave pattern.

External interference can be pretty much ruled out at this point. I noticed the missing negative half. The evenly spaced spikes do shift in frequency once in a while but not very much, still in the 18600 18700hz range, than slowly shift back to just above 18500hz. They always stay evenly spaced, they maintain the same distance from each other. They are over 20db in amplitude and if I really zoom in, the tips seem so narrow that it doesn't look like just an analog signal.
It would really help to see if anyone else can turn on RTA audio analyzer on their V60 and find out if they see the same thing.

Hi I just noticed that when I attach the second screen on the v60 theres another spike that appears immediately preceding the others and goes away when the second screen is off. Perhaps this is where at least some of the spikes relate to. Still very curious

Poor circuit isolation.
Whatever the cause(s) with a stereo signal in open air listening area those spikes will be audible when those sound waves interact with the other audio frequencies to produce secondary waves in the audible range.
With sealed systems like headsets, buds etc few can hear them directly, but some can especially younger females.
Interesting things do happen when I bring it next to a plugged in guitar pickup. Even with airplane mode on, no wifi and screen closed. I guess I was hoping for it to be intentional rather than not.
