[Q] Static/White Lines on Edge of Screen - Asus Eee Pad Transformer Prime

I was using my TFP while brushing my teeth this morning and noticed something very strange. Did my diligence and didn't noticed anything else on the forums about it.
The TFP was on the counter as I was reading through the morning's posts via Google Reader. I opened a link that went to the stock browser and noticed that after I stopped touching the tablet, it developed some white lines, maybe 3/4 cm long and 3 mm or so apart, all along the length of the left edge of the tablet while it was in landscape orientation.
When I picked it up, the problem went away. When I put it down, it happened again after a second, so I picked it up again, and it went away again. This time I took a closer look to make sure my eyes weren't playing tricks on me, so I was holding it a bit longer. After I put it down, the problem didn't reappear, and hasn't yet happened again, even after carrying it into work with me.
Has anyone else had this problem? The lines went down the entire edge and into the back button. The lines weren't static either, changing length horizontally but not vertically.
I'm not sure if it's a hardware or software problem, but either way, I'm inclined to exchange, return, or RMA it. Starting to have enough minor problems that it's becoming a major fuss.
--edit--
Now that I think about it, I had just showered - humidity could be a factor, but that was like 20 minutes earlier.

white lines
I had something very similar happen yesterday..see pics.
Btw. Steamed music and Bluetooth connected to Bose with no problem.didn't try video.
Received mine via UPS from Best Buy at 4pm, returned it at 8pm. BB ordered a new one, which will arrive 01/14.

Wow, mine didn't do anything nearly that bad. Maybe that's the next phase of this issue though.

my tf201 has this problem occasionally as well.
it seems to be a memory/multitasking issue in android itself.
on my tf201 it happens when switching from a game to a non-gpu or graphics intensive app.
simple solution is that you need to kill some of the tasks in the background, then restart your app. then it goes away.
it seems to be some kind of memory leak in the graphics subsystem...

Whew... As long as it's not some sort of physical damage, I can live with it

It went away with newer firmwares. Pops up once in a while, but I think it's related to the graphics system. If I unload everything from the quickswitch, the triangle issue and this one don't occur anymore.

Anyone figure this out? I get it the odd time as well.
See attached. (The vertical lines in the picture are just from the camera.)

i've been getting the same problem with mine, just recently, i've done a hard reset but it comes right back. I requested an RMA from Asus, is it worth sending in and is it something that is fixable or is it just a software issue with 4.0.3.
And where is this quickswitch that you unloaded everything from..

i mailed it back, i told them i either wanted the wifi & the static lines fixed, a refund or an upgrade to a 700. Not that they care

Hero keeps "scrolling" to the right...

Hi
I have a weird problem...
Sometimes (not always, but like once every two days), my Hero just scrolls to the right in like every app... even on the homescreen
For example:
-on the homescreen, he scrolls to the right, so towards the last homescreen.. I scroll back, but de hero has its own will and scrolls to the right again...
- in the browser the Hero scrolls to every link (like I would scroll with the scrollbal to the right and it jumps from link to link)
- in an app with different tabs (like People) my Hero also scrolls to the tab on the right, so he goes from "all contacts", to "faorites", to 'groups", to "updates and events" etc...
- in messages, when I want to begin typing, the button "send" is selected in green (like I would've scrolled to the right)... when I'm typing, it doesn't occur..only before I've started typing...
also, I've noticed that like in the browser, when I hold my phone horizontally, the problem doesn't occur.. and when I hold it back ertically, the problem is gone (I think....) ...
Anyone who knows this problem ? Pretty weird, I know
Thanks in advance !
greets
PS: maybe it has to do with the G-sensor (cfr. holding horizontally: no problem...)
I guess that your problem is the trackball, it may be a bit loose on one side so that it will roll sometimes to the right.
Mine does this from time to time. I think it is dirt under the trackball. I just sping the trackball round a few times and it goes away.
HTC support instructed me to send the device to warranty repair due to this issue. Haven't done so yet, though.
Same here, also i think that is a only dust.
After re-spining TB it goes back to normal state
This has been demonstrated a common problem with the Hero. They told me to restore the firmware which is bull. Something's broken, hardware or software we don't know but I should think hardware.
Yeah, I'm still not sure whether this issue is software or hardware related. The whole dust thing seems a bit weird. Especially when my Hero accidently did this -right- after I got it out of the box and started it for the first time.
It's annoying though, but a flick of the scrollwheel always fixed it so far. (or reset)
Ah... I posted previously about this- My fault. Looks like a common problem.
Has anyone found a solution that works?
I also have this problem, for a while I thought it was only me...
I have same problem from time to time, not very frequently.
It's not a "dirt" problem, it has something to do with magnetic fields, which affect the trackball's logic. That's why you see this from time to time, at special areas.
Since a couple of days I have a new problem... the automatically scrolling to the right doesn't seem to appear anymore, but now I can't scroll anymore to the right with the trackball... all the other directions work... could this be software-related then (it cannot scroll anymore in the same direction it used to scroll automatically to...) ??
if it is just dirt... nay idea how to clean that? I've tried rolling with the TB a lot in different directions and even tried with a light moist cloth...

What, the Earth's magnetic fields?!
Actually that would explain a lot! I followed the textbook advice, and re-flashed the ROM. All was ok until this morning, and the screen started leaping left, rather than right!
...So I've reset the device, and downloaded the ROM again, and reflashed.
I have to say, I'd be surprised if it was a "dirt" problem, because every HTC I've ever owned has been very well sealed. (Unlike my Nokias!)
Is there any way to test if it's magnetic? (I guess "with a magnet...")
Ths has been discussed in greater detail here.
http://forum.xda-developers.com/showthread.php?t=546206
Hmmm... no closer to an answer though. I'll see if my re-flashing helps and will let you know.
I'm not sure it's worth returning my unit: sounds like it's a generic defect.
My network definately alters a lot as I travel a great deal. And I'm often in/out of Wireless zones.
Yesterday I tried the simple solution I turned off the device... put it back on.... and everything seems to work properly now even the trackball scrolls great again... don't know about you guys, but this solved the problem for me sometimes, the answer is just around the corner...
It happened on mine today (this morning when I came in to work) but it went away after it warmed up. It was cold this morning (2 degrees C or so).
It's not associated with WiFi, and I've tried resetting, reflashing and even switching off.
The problem keeps coming back though. It's completely random and really annoying...

I am convinced this is a software issue. The problem is easy to reconstruct:
It is as simple as this: If there is data traffic in the background while on Edge network, this happens. I cant see how this could be a hardware problem. I have found this since I am on a train 3 hours every day and has had a lot of time to figure this out.
Sadly I havent found a way to disable edge network.

That's useful: I also commute daily and I think yours is a likely solution.
I just wonder if this is a problem with a batch of Heros... otherwise you'd think everyone would be suffering. It sounds like if I exchange my unit, there's every chance the new one would have the same problem.

Problem with screen (8Bit color/bleeding)

Hi
I am having problems with my screen. Looks like the LCD is faulty. Trying to resolve with Samsung Support, but thought I would ask here if this is a known problem or if there is a simple fix.
It looks like the grayscale colors are not right, I installed a screen tester and the grayscale bars have a red tint. all other tests in the appl look ok. however pictures/video's all look like they are 16bit color and icons look like they are bleeding
Here is a picture of the problem
imageshack.us/photo/my-images/836/atab1large.jpg
Any thoughts?
Eric...
Looks like a faulty panel !
Take it back to where you bought it and have them exchange it.
Sent from my Galaxy10.1 TouchWiz/ADWex equipped Starship.
I have exactly the same problem Tablet has been bought in the United States and now I am in Europe. Samsung won't repair/replace it anywhere in Europe. Only US Samsung offered to help me but the tablet needs to be at a United States address. Now I have to send it back to someone I know.. will take months
Well my problem disappeared.... not really sure why/how, but I have been playing with different ROM's etc. and I THINK it might of been when I did a permissions repair, but...
Plus i'm 99.3% sure I had the problem before I rooted/ROM'd
Another reason to stop loading these 3rd party ROMs. I dont understand why people are installing these 3rd party ROMs to begin with. The stock ROM is by FAR the most stable and error free ROM you can use. Most of the issues people are starting threads about would have NEVER occurred if they just stuck with the stock ROM.
I get this too now. I've been pootin' around with different roms for a while, no problems. Then a few days ago while I was running GalaxyTask 8.0 the "bleeding" started slowly. First around the edges of things, but then the entire screen. The colors seem to color-cycle into the end result. I figured it might be the rom so I tried a stock one. And then I tried a complete stock reset with stock recovery and factory reset - the works. No change. It's still like this. And in the bootloader and the recovery too. Sometimes it gets moments of clarity, everything is fine, but only for a few seconds.
Busted tablet? I bought it while in the US this summer, so taking it back will be an issue. Getting a Transformer Prime late next week *fingers crossed* but still. I was hoping to sell this fully functioning :|
Example:
http://dl.dropbox.com/u/120921/IMG_20111214_214938.jpg
I had the same issue. Also bought in US while I live in Hungary. I had to send it back to my relatives who took it back to Samsung and they replaced it in warranty. Fortunately, I was travelling there by the time we got the new one and I could take it back home with me. This seems to be a weakness of the tablet. My replacement unit has been working nicely ever since.
I had the same issue with an August build stock tablet from the US.
Thankfully Samsung UK took it in for repair and ended up replacing it as it was apparently unrepairable.
My issue used to show up with 60+ minutes of continued use. I think it was thermal related as the warmer it was the quicker it seemed to develop the fault. putting it on standby for a few minutes used to clear it, but the problem would come back quickly as it was warm.
Anyone know how Samsung handles this issue if the device it out of warranty? Mine is acting up pretty bad and I haven't been able to find anything on here about repairing the issue on your own. It will be clean view for a few minutes and then the color bleeding some background effects kick in making the tablet a large paperweight. I've been looking for and excuse to get the 10.1 Note, but it sure would be nice to get a few bucks for this since it's in perfect condition... besides the screen.
My 10.1 is starting to develop the same issue. Never been rooted, always on a stock rom. I've never dropped it or banged it around. It also seems to start happening afternlonge usage. First imsee a few purple lines across the screen and then the entire scren turns to 8bit colors, etc. Once I turn it off and back on it goes back to normal. Annoying, especially simce I bought it 13 months ago so I'm guessing it's past the warranty period.

I'm with you - mine has never been rooted or tampered with. Other than getting heavy usage, I've taken perfect care of it. I've been unable to find a fix.

If you're out of warranty you're on your own. Samsung won't repair or replace it for free.
At this point I'd just like to know how to fix it and what it would cost, ballpark. I haven't been able to find anyone who's delt with it, bar throwing their tablet.

My 10.1v just went.
Guys, I'm having the same issue today. And here is the fix:
1. Take out the back cover.
2. Look for the black cable that have SET printed on the end.
3. Removes both ends and then reconnect.
4. Push/rub at both ends while the screen is on. You'll notice the tint-colour of the LCD will change. Stop when it looks normal again then put a tape on top to hold the cable in that position
4. Put the cover back and enjoy your Note 10.1 again
Good luck!

touch screen "kinda" failure?

well i have an odd problem, one one section of my screen doesn't pick up touches, only the area where the "C" is on the keyboard...its annoying due to thats where the OK buttons are...
i can still navigate sense i can use the track ball..
anyone else have this issue, or something similar?
Try wiping back to factory if stock or reflash the rom if rooted?
I had a weird issue with the touch screen on condemned 18.3 where on the lockscreen trying to drawdown the slider and then draw the pattern, it would freak out and glitch and not follow my finger at all and take several tries to get the pattern correct.
I then wiped and flashed the latest 4.0 GSB and haven't had any issues since.
That's not quite a touch screen failure as yours is, but I thought it would help as an example as something gone wrong and how I was able to remedy it.
i've tried flashing a few different roms, went from cs18.3 to a 2.1 sense rom, back to the latest gsb. it appears its must be a problem with the digitizer...
really sucks, i have to wait to april to upgrade this phone...
might be on craigslist looking for a cheap droid 1...
Ah man, that's unfortunate. Probably wouldn't be worth it to try to replace the screen/digitizer either. Yeah, that's probably your best bet, looking to get another phone. That's how I got my Eris, from craigslist. Great way to go about doing so.
Good luck to ya.
I actually have the same problem and something leads me to believe that an update is causing this. I had it bad a few weeks ago (can't press C, V or X - though I can swipe to the keys sometimes) and then I got a few market updates for Handcent, SuperUser, and something else which then cleared it up for a few days. Then I got more updates and it's back to the failing keyboard!
I really don't know how to pin point it and I haven't done any resetting or testing yet, but I have like gut feeling something is wrong with the software, not the touchscreen since someone else is having this problem.
Mine has been failing little by little. Im now down to the top right corner, bottom left, and bottom middle not responding. It hard to even get the apps drawer to open. It all started with the letter C with me too. Just gets worse.
****, my whole qwerty row doesn't work, neither does the trackball. Upgraded to a SGS2, but I still tinker with the ol' eris.
mine moved, it started working fine for a few days, then just a smaller section to the left of C doesn't work, only really effects when i have an "OK" to press...but track ball still works and typing is so much easier now.
my wife thinks its because i dropped my phone that it started working again
I know this thread is a couple of months old, but...
There's an area on mine at the top right below the notification pull-down that appears to be dead. I'm thinking it's because I've dropped it about 10 times, but nothing looks wrong with the screen otherwise. I've thought about buying a replacement screen for about 15 bucks, but I'll be able to upgrade at the end of March, so I'm really just thinking about holding off (though if the new screen/digitizer worked, it'd make for a good mp3 player with the wifi script).
Digitizer is going bad. Same exact problem happened to mine. I replaced it myself and it works perfect. I found how to videos on youtube and bought a digitizer for about $37 online. Only took a half hour to tear apart and replace. On the difficulty level, I'd give it a 6 or 7.

YMMV.
Someone gave me an Eris that had digitizer problems along the lower left side of the screen (in portrait orientation). I bought a replacement digitizer ($22 iirc), installed it, and it worked perfectly - for about the first 30 minutes. Then, the problem re-appeared in exactly the same location with the new digitizer.
Same behavior for a variety of stock or developer ROMs, so highly doubtful that it was a "software problem". Very very odd - the chip that does the capacitive sensing is on the flex circuit attached to the digitizer, so it gets replaced when you replace the digitizer; I suppose that the signals that come off the mini-connector between the digitizer assembly and the phone's mobo are only power, ground, and I2C signals.
But there you go; taken all those observations together, I'd suspect that I had a problem on the phone's motherboard which was thermally dependent.
Despite my (negative) experience, the odds are still in favor that a digitizer replacement will fix the problem; but there is an outside chance that it won't.
just sayin',

Screen flickering madness

I got my 920 today and I'm quite happy with it. However I'm facing a weird issue. My screen is noticeably flickering. At first I tried to restart the phone a few times, and at last with a soft reset I got rid of it in some areas (eg the unlock screen) but in some others (typing an address in the browser, typing into Bing search) it's still there, even tho it's not very noticeable anymore. However I'm quite picky so it annoys me a bit, also I don't think it's fair that I have to use a phone behaving this way. Anybody else having this? Workarounds of any sort? Otherwise I guess this guy is going back to the store...
Edit: I found out that this issue pretty much comes and goes randomly, I happen to have it for a few hours then it goes away, so on so forth. I really don't know if I'll ever be able to get the phone replaced if the issue is so hard to be reproduced.

You're not going crazy as I have the same issue with my 920. It is VERY intermittent and probably happens about once every 3 weeks I guess.
I'll wake the phone to check it and it seems that the display is not working fully and looks interlaced and flickering. No loss of functionality and when I put it to sleep and wake it up a few times it's fine and back to normal. Appears to be an intermittent issue with either the display or drivers but no way to reproduce unless you separately take a video/photo of the screen when it is in this state when you are returning it to the store for an exchange. For me it doesn't happen enough to really worry me although it is slightly annoying...

Man, this is driving me nuts. I noticed it does it every time the phone reaches a somewhat hotter temperature (like body temperature, a couple minutes of usage normally) or when it's plugged. When the battery is 100% loaded it usually stops, but then after a few minutes it comes back, very annoying. Since it does it like 90% of the time I guess the guys at the shop will notice it, when I'm at max brightness it's like a freaking strobe, I can't take this any longer, makes my head ache. One thing I also noticed is the fact that the lowest light setting available is still way brighter than when on auto in a dark room: low looks more like medium, so to speak. Is this ok?
Today I'm bringing it back to the shop anyway, I'll keep you posted.
Update: I got my phone replaced. We had to open 3 boxes before finding a non flickering one, insane. For the last try I decided to open a white one and it was flawless, weird...
Are you guys in cold areas or keep your phones in cold areas? By cold I mean under 65 F. I have noticed in certain types of LCD's that if they are cold they seem to slow in refresh rate. Try warming your phone up and see if it gets better.

Not really my case I guess, actually the phone kept acting up even after an hour usage, so it was plenty hot. No problems with new one so far, fingers crossed...

Anyone having touch screen issues?

I was so happy with my first Sony Z2, I decided I wanted a second one and bought me the 32GB version a few weeks back and gave my old 16GB one to my wife. I have been using my new tablet abit lately, but I get periodic issues with the touchscreen. Most of the time everything working fine, but then suddenly the screen will only respond to very hard touches, and something like picking up a icon and moving it on the screen is impossible. If I try to press and move it, sometimes it will open the program, and sometimes you can see I'm picking up the icon but it looks like im dropping the second I pick it up. Then 5 minutes later I can pick up the icon and move it around on the screen no problem.
I'm not sure what to do since it's very random. I'm not sure if I should bring it back to the shop, or do a factory reset first. It's very random, and often only last a few minutes before the effect is gone, but when it's bad it's almost impossible to do something like typing. Anyone else with issues?
I think there was a screen diagnostic menu somewhere, anyone recall where this was?

You should have red this topic before buying : http://forum.xda-developers.com/showthread.php?t=2735460
One of the hottest post of the z2 tablet forum.
If It's possible for you get a refund and buy another tablet.
I have it since may and it's definitely my last Sony product.
Indeed I should, noticed after reading this that my tablet is indeed bent as well... So back it goes then!
I also have a 16GB version, and I have zero issues with that, been a very good tablet for me but the 16GB size is very limiting.
