Screen Flicker

So, I just bought the tablet today, and I really like it, minus a rather strange issue.
I read about the firmware update to .29 that would resolve the screen flickering issue, but when running the firmware update out of the box I am now on .30, and the screen still flickers.
I have played around with settings and such, but I haven't found a way to get rid of the flickering, even on the latest firmware. Is there a way to resolve this? Perhaps flashing the .29 firmware when in recovery, and if so how do I do that?

And it is not just specifically the "flicker from the left side of the left side of the screen" issue. It seems to happen all over the place, it is really noticeable in the app drawer, all the icons flicker like the image is unstable.

Hi, I just got mine as well. I had some weird flickering issues which I managed to get rid of by turning off the auto-brightness setting. HTH.

No that didn't help...in fact that seemed to make it worse. I am starting to wonder if its a hardware defect. I do have two weeks to exchange it.

Try doing a factory reset. If that doesn't work return it for an exchange.

I actually did that last night. Still the same thing. Must be an actual hardware defect. I assume other TF300 users do nit have this issue?

Disable SmartDimmer

I got my TF300T a couple of weeks ago and I'm generally pleased with it but one thing that is driving me insane is this auto contrast / brightness function that is always running on this tablet. When watching a movie or youtube clip with bright content then you can clearly see the brightness and contrast constantly changing, most visible on low brightness in a dark room.
I have not rooted my tablet yet but I think I'm going to do it soon, but today I saw this fix from the TF700 forum and I was wondering if this also work on the TF300?

Has anyone tried it yet, because if it works then I'll definitely be rooting it.

I haven't tried but I don't see how it wouldn't work, since the original tweak was found by a nexus 7 user.

This path wasn't correct for me - /sys/devices/tegradc.0/smartdimmer/
I had to use /sys/devices/nvhost/tegradc.0

Oh god thank you!! I'm gonna try this tonight, the auto contrast thing was driving me crazy.

hey this problem only happens in power saving mode, right?

Sadly, cannot seem to find any fix for non-rooted device like mine atm. All my android devices are usually on auto-brightness but it's unusable in tf300, that's my only gripe on this pad.

Noob question. I don't know how to do this. What's su? What's terminal? Please help me what do I need to do to disable this feature, thanks. Mine is rooted.

Download Terminal Emulator from the market and then type in the commands. When you type SU in terminal it gives superuser permission to the running terminal so you can type in the tweaks.

If I unlock the screen, around all the texts there is black framing until after one second or two it goes away...is this the auto contrast?

This doesn't work for me on my 300. It's an invalid directory because there is no tegradc.0 folder under /sys/devices

Use this path:
echo 0 > /sys/devices/nvhost/tegradc.0/smartdimmer/enable

What does echo '0' mean? Is it a terminal command or do you have to usean explorer to move some files?

Terminal command, its not a Real file, you cant move,copy, delete or edit it the regular way

Infinity problem after JB update

Hi, after I updated my Infinity with JB, I noticed the screen ocasionaly flickers, like for half a second one random line of pixels on the left side turns black, and other distortions, very ocasionaly and quick. Is anyone having problems like this?

yeap, sometimes a white horizontal line appears for a second o less in my tablet. I have to tell you that I don't have yet "the buttery" in it. Waiting to have time for a factory reset to improve the performance.

I saw other posts from the prime and the infinity as well, that after a while it gets worse, and a factory reset doesn't help at wall. I whant to resolve this without having to exchange it. I'm sick of having to go to the store and exchanging it. It's my 3rd Infinity.

I have not had what you described above happen to eithor the TF101 or TF201 I had prior to my current TF700T. My TF700T has not shown any of the issue you described after my upgrade to JB. It sounds like something you should take up with Asus right away since it could be a hardware issues and would be covered by your warranty.

anyone else?

I also get a screen flicker since upgrading to Jellybean on my
rooted TF700. I suppose I'll try a factory reset and will report back.

I also get it....was wondering of it was just me. I got my new infinity a couple days before the JB update so I wasn't sure if it was a result or not.
Sent from my ASUS Transformer Pad TF700T using XDA Premium HD app

Yes, it's a JB issue. I've only had it happens once, not seen it since.
It's just screen tearing. Happens on a pc, too, although there videocard drivers have Vsync options to forcefully match the refreshrate from the program to the screen to prevent screentearing. I suspect there's a difference between JB and the Transformer's refreshrate.
We're using an Nvidia card, has anyone send Nvidia a message? (I don't have the problem anymore, so I can't make a support ticket...) More likely to work than wait for Google or Asus to notice.
Also, I don't have root nor unlocked, but tp anyone who has, is there a way to change the refresh rate manually?

Should I do a factory reset after updating to JB? I noticed that it got faster, etc... But was wondering if it would still improve after a factory reset. If yes, how do I do a factory reset? And is there a way to have my infinity exactly the way it was (wallpapers, configurations, apps, etc.)?
So I shouldn't return my infinity? If it's a software problem... I'm sick of having to return this model.

I also have problems with my tf 700 after last update... tf 700 is having sistem freezing and restarting.

I have also the same issue than OP. I contacted Asus by email to try and figure out what's wrong. I got the tablet on Monday and upgraded to JB right away, so I don't know if the problem was there before in ICS. But reading this thread I think that it's related to JB. It's a "good thing" though, because this is my second TF700 and I don't want to send it back, again. The first one had a very white spot in the middle of the screen..*. But no flickering black lines issue.
So, you guys think that they can fix this with the next release?

I'm getting this too from time to time. Very annoying!

Are any of you setting options in Settings->Developer Settings? I have heard that the "Force GPU rendering" option was causing random reboots for some.

I'm really not sure then. Personally, I haven't had a singe reboot and/or SOD though, so it must be something specific to the setup for the folks that are having this problem. If you really want to figure it out, I'd suggest a factory reset and try running the tablet without installing all of your apps/tweaks at the same time.
How often does this happen? Can you try running a "bare-bones" setup and see if it still occurs? If not, then slowly start introducing your specific apps/tweaks one (or a few) at a time. Yes, it's a pain, but it's the only way to diagnose such issues... Have you tried looking at logcat outputs at all? That's another way to try and diagnose the problem. These types of issues are very hard to troubleshoot - it's a slow, tedious process. But, since most folks aren't seeing random reboots and or "sleep of death" issues, it is fixable (unless it's a hardware problem, of course).
So, here's a few questions that might help troubleshoot:
1. Has this always happened on your device or only since upgrading to Jelly Bean?
2. How often does it typically happen?
3. Have you tried installing Jelly Bean from scratch (not upgrading ICS)?
4. Are you installing your apps "fresh" or are you restoring them via Titanium backup (or some other backup app)?
Again, there is no quick, easy solution to this type of problem....

There's another thread going on this too.
I had a few lines and flickering day before yesterday, haven't seen this at all the last 2 days.
Another poster on XDA had mentioned that new OTAs take some time to settle down.

I'm back to ICS. Since I never ran my tablet with it (got it and upgraded right away), I want to make sure it's not hardware related. So far, no black lines... I won't upgrade to JB until they solve this!!!

Contrast degradation

I noticed my TF700 is suffering from contrast degradation after prolonged use. I could be using the browser and then the screen seems to kinda whiten up a bit more then usual. It's still readable but noticeable. Wondering if anyone else is noticing this and if it has been noticed does it get worst because mine is happening more often now.

Turned off Auto Brightness?
Turned off Battery Saving? Not the speed toggle, the one in settings that turns on when battery gets low. This has an auto-contrast.

So that settings / power savings / first selection battery saver. Thanks I will post results.

It sounds like the effects of the Asus "Smart Backlight Adjuster". Go to "Settings->Asus Customized Settings->Enable Smart Backlight Adjuster" and uncheck that option - I think that will solve your issue... This is completely different (and separate from) the auto-brightness setting.

It starts up fine then after a while when it gets warm everything gets lighter. More noticeable when browsing the web.

Hmm, that actually sounds a little more serious that just the setting that I talked about a few posts back... Almost sounds like a hardware issue.
Let us know what you find out - a picture would also help. In fact, if you take a screenshot with the TF700 and post the picture and the picture looks fine, then it would definitely be a hardware problem (the screenshot would capture what is supposed to be displayed - if it's a hardware problem, the screenshot would look normal to everyone else, but would still look bad to you, if that makes any sense)...
Sent from my ASUS Transformer Pad TF700T using Tapatalk 2

I have the same problem, noticed yesterday for the first time. It looks as if contrast is lower and brightness higher than normal.
I am still within my 30 day best buy return period, should I consider returning it? I have unlocked it, would best buy care?

Touch Screen - Digitizer Problem

Out of nowhere today, I started having problems with my screen. When I press the left middle of the screen, it shows me pressing 2 inches above that. My keyboard in that area, is non responsive, and when I'm in apps and trying to navigate, it gets all haywire on me.
Is their a way to get it calibrated? To stop the intermittent failure of my screen in certain areas.?
Sent from my ASUS Transformer Pad TF700T using Tapatalk HD

Is this happening with power connected or without?
Saw a neat clip once of the screen's different feedback between connected and not. When was connected to power, user showed how his touch input resulted in erroneous touch all over the place.

At first I thought it was during connection. But now it happens intermittently with other without power. When I called Asus. They said it's the "Digitizer" I'm under warranty, but If theirs a fix we can do on our own, I'm all for it.
Sent from my ASUS Transformer Pad TF700T using Tapatalk HD

Unfortunately, it probably is hardware-not software related. Get a RMA and send it in....
If you want to narrow it down some more, you could enable"show touches" in Developer Options.
But I doubt that it would help...

That's exactly what I did, to know that when I touch one spot on the screen, it showed the actual touch, two inches above where I was actually pressing. What's maddening is, it doesn't happen all the time. Just different times throughout the day.

It does sound like a hardware issue with the digitizer. Sending it in might be the only way to know for sure and to fix it. It is under warranty, so you won't be charged anything. Try doing a full factory reset first before sending it, though. There could be small chance that it fixes it that way.
