Hello all,
I have been using my TF700 for like 3 weeks now. Yesterday suddenly it started to flicker. First I tried cold boot and it turned normal but today it got even worse. It stops randomly and then starts again.
so should i return that or is it just software issue? (dammit i cant out the youtube link)
EDIT: It fades away after like 10-12 seconds, do you think it is software related? Using latest firmware btw.

"5. Disable "smart dimmer", which is the reason you can see some screen flickering when changing between light and dark backgrounds that many find annoying (described by some as "dynamic contrast", which it resembles):
To disable:
echo 0 > /sys/devices/tegradc.0/smartdimmer/enable
To re-enable echo 1 to the this file or simply reboot.
Be sure to include this in a script so that rebooting won't change it (just make an .sh script with the above line in it, you can use either SManager or system .sh scripts (you can use my simple solution posted here if you don't like editing files yourself). See also jtrosky's hints on changing the brightness settings.
Please note that it may negatively affect your battery life, although with brightness set low it shouldn't be much worse.
All credit goes to those who have found out about it - see this post for details."

thank you for your reply. it just occured that for example when there's a flicker on the screen, if i turn on auto brightness, it goes away.
the thing is actually i do not know if it is software related or just bad hardware. returning it to amazon would push me in a lot of trouble (like shipping it back, waiting for repair or sth) and the biggest problem that i don't have that much time.

I'm under the impression that the autobrightness and the smart dimmer are two different things. The smartdimmer cannot be turned off without doing the edit i pasted above. Try it out and see if it works for you
omg this is totally not normal right? it got even worse(see attached pics)

Um yea, I'd get that replaced ASAP
Yep - that's the same kind of graphical glitches that I had before I rebooted and my TF700 was dead (although my glitches weren't quite as bad). After rebooting, my device would just lock up at random places during the startup - sometimes at the first screen (where it says your device is unocked), sometimes at the Asus screen with the circles and sometimes I could even get to the Android lock screen (or even further), but in the end the device just keeps locking up hard. Tried all of the normal "reset" stuff including going back to complete stock, unrooted, etc...
In my case it's definitely a hardware problem, but since I was unlocked, I can't even get warranty service.
Just curious as to your locked state, rooted state or if you were running a custom ROM...
Thanks.

luckily i haven't unlocked it yet and i am sending it back to amazon for replacement. hope i will get one without problems, but i have some doubts about it after reading hundreds of complainings in forums.
My screen sometimes flickers when playing a game. The game also crashes at this point. I wonder what this issue could be. After a cold boot it usually works fine for a couple of days.
I've only had this tablet for 2 weeks now, but some issues like poor io performance, screen flickering, and the screen flex on certain points on the screen are really annoying me. Maybe I should go to the retailer and ask for a replacement.
So I got a refurb tf300 from Woot the other day and it looked and worked like brand new until the touch screen stopped working completely. Left it be for a couple hours and came back to find it working. This happens a couple times a day, it stops and then it starts working. I can occasionally get it to start working again if I flip the device around any which way but there is most certainly an issue with the hardware. I have a feeling it might be some sort of loose touch screen issue.
To make matters worse, I unlocked the bootloader and rooted it to run CleanRom (great ROM BTW!)
I've heard Asus's RMA service is a nightmare (especially with it unlocked) so I wanted to check in and see if anyone has heard of this or has any ideas of how to fix it. Since it's clearly hardware related I can probably have them fix it but don't want to be out a tablet for six weeks.
Have already tried a handful of cold boots per recommendations online.
Cheers

I should start by saying I'm not that new to android, but I am by no means an expert and have not been able to figure out how to get out of a very confusing situation.
My tf700 is currently running 4.1.1 Jelly Bean and the newest firmware version 10.4.4.23. Before the firmwarm update, I had unlocked my device thinking that I would try out some of the newer roms based on many recomendations from the facebook Infinity group. I never got around to rooting and installing TWRP, and a few days later I updated to the current stock firmware version manualy (downloading zip from website, flashing from stock recovery). Everything worked great for the first 2 days, and I had compeltely forgoten about rooting/romming thinking that the risks far outway the reward as my device was already near perfect. This morning my infinity began to act funny. Touch responseiveness was awfull (about 1/3 times I pressed, it would react) and it would sporadically stop charging while connected to a power supply. Some time later, while I was watching a flash video my screen turned completely blue and I force restarted it by holding the power button. From then on, I could not turn on my infinity and I tried EVERYTHING (pushing the reset button with a pin, trying a cold boot, holding power for 30 sec etc.). When i tried any of these combinations, the device would start vibrating and the vibrations would not stop. Also, the screen remained black the whole time and nothing I did would even get me a faint glimmer of any sort of screen response.
Has anyone had this sort of issue? I do not think this is a firmware problem seing as it worked fine for 2 days with this firmware and I am at a complete dead end as to what to do. Because I am unlocked, I can not send in my infinity for repair as my warranty is gone. Any help with this issue would be greatly apreciated!

Update:
I can now rarely get it to vibrate for even a second holding the power for a long long time. Screen does not come on at all. Looks completely dead.
By your description sounds like a dead or dying LCD.
Sadly RMAing to Asus may cost you out of pocket.
Where did you get the tablet and how long ago?

I was hoping it wouldn't lead to something like this. I got my tablet from Amazon around the first week of september. I have treated it very well.
I'm not quite sure how it could have burned out, my brightness is usualy <50% and I have used the super IPS+ more less time than I can count
on one hand. If this is the case, Is it possible that a technical problem like this would still be repaired on warranty seeing as it has nothing to do
with the bootloader?
Also I'm not sure how this explain the constant vibrating that does not turn off untill the battery runs out. The way I see it is you could be right, the tablet is trying to tell me it's not going to work, or there is really some kind of software glitch.
Have you ever had LCD problems with a tablet? any idea how much this could cost?

I've not had any manufacturing problems with my tab.
I don't see anything you may have done that caused the screen to go bad.
Sounds odd yet a few folks have had their tablet just start working again after seeing similar dead LCD's.
The vibrate thing is weird...almost like a bootloop with no screen.
There's a chance Asus may co-operate if you contact them for an RMA.
It's worth a shot...not sure if Asus has any standard repair rate for this sort of thing.
Curious do you see the back-lights in a darkened room?

Thanks for the advice, I have heard some terrifying stories of Asus customer support (never had a problem with them myself) and of devices just being completely lost in their care.
To answer your question, no the back lights are not visible at all. The only way I know the Infinity is somewhat alive is by the led coming on while charging and the somewhat random vibrating patterns that happen when trying to boot up.
Hello everyone!
I have been visiting the site for a long time but this is the first time I actually post.
Well the problem I have with my nexus is that the screen stopped working a few days ago, but the touchscreen is still responding. I was walking at the beach with the phone in my pocket and after some time I realized the phone was not working. I suppose it was the humidity because the phone was completely dry.
Now the weird thing is that the touchscreen works perfectly, I can feel it when I unblock the phone, but the screen is completely black. Anyone has any idea how to fix this? I already changed the screen of my old nexus 4 a few times, but is there any other option? because I do not want to pay for the whole screen replacement when the touchscreen is working. I would say that it is just some contacts not working properly, but I do not really know how to fix that.
I hope someone has an idea how to fix it.
Thank you!
Maybe this thread will point in the right direction. Mentioned is flashing stock recovery.

Thanks for the reply! I tried that but it did not work and after the battery run out I realized it was not charging either. So I think the only thing left is to send it to repair to LG or something...
Hi,
My OPO is having some strange behaviors when it comes to the touchscreen. Not only I'm having the ghost touches (still no fix out, right?), but I'm also having a strange bug that makes the center portion of the screen unusable all the freaking time.
I made a video (sorry for the bad quality, the glitch about 25 seconds in and the general noobness ) showing the bug in action (sometimes it happens on the lock screen, which is infuriating cause I have to way of unlocking and have to wait until good guy OPO gets his **** together).
Anyway, is there anyone with a similar problem? any fix on the mind of an illuminated soul? or to the warranty (or lack of it) with it?
Thanks.

I have it too...When i wake up my phone sometimes i have to wait a few sec before the screen becomes responsive...It must be something related to touchscreen software or drivers, theyre really bugged as now.
Yea I also have it, I had it yesterday when i had to call cardstop when my wallet was stolen and my screen wasn't working.
Powered off for 5 min then only the bottom of the screen was was working.
hey guys Abhisek Devkota of CM says that is a firmware related issue caused by partnbers that gave drivers to cm..they now are working hard for it and in this month should be two updates..the firts with the workaround on the ota in the next days and the second with kernel patch

I hope so, its happening almost every time I unlock/try to unlock the phone now. its really annoying, specially during calls, yesterday I called a friend and he didn't pick up so the call went to the voicemail, since I didn't want to leave any message I tried to end the call, but because of this bug I had to put the phone to sleep and wake it up to end the call making me pay for a dam voicemail.
Any news on a fix for this ?
I am having this issue as well but it just started today and I have had the phone for about 3 weeks. After a few minutes of use my touch screen except for the navigation buttons and the status bar become unresponsive and I have to power cycle my device to get the screen working again.
It happened to me today as well. I sure it will be fixed but still glad I have my Nexus 5 till then.
I have found a temporary fix (at least for me). After trying out many different kernels I ended up with the XNPH22R Kernel (http://forum.xda-developers.com/showthread.php?t=2780725). After a reboot the screen frooze but then recoverey without reboot. Now I had no freeze for around 30 hours without reboot. Still running the XNPH25R CM11s Rom.
Phone is rooted and unlocked.
There are also speculations that the freezes could be temperature related or at least partially.
