Hi there.
Sorry for asking that if the subject has already been discussed before but I searched for a solution and didn't find anything for this particular one :-(
My problem is that the touch screen of the Transformer is being timed out sometimes...
There is no black screen and the tablet and display seem to work but not the touch screen... To avoid this problem, I must push the on / off button one time and then another time rapidly, then unlock the screen, and then it works with no problem for some times.
Some times, I let it sleep, I unlock it, and it doesn't work good for 10 seconds, until I can't touch anything more, so again, I must push the on / off button.
And some times, I am just playing with it and then it doesn't respond well and little to little, go to time out...
It is a really annoying bug.
I had this problem with 3.0 stock, 3.0 prime, 3.0 prime and clemsyn kernel, 3.1 prime and clemsyn kernel, 3.2 prime and clemsyn kernel...
I am really going to think it is a hardware problem ((((
My question : does someone here has the same problem / found a solution / know what is the problem / want to discuss about that ?
Thank you in advance.
I am having the same issue -- this is the most frustrating issue that I have with the TF and I have not been able to find a fix --
I have had this problem from 3.0 -to- 3.2 with all roms/kernels in between. It does seem like it is an issue with the capacitor-- any humidity or moisture causes it to go out of whack until I put it so sleep, then wake it back up.
I have one of the original batch of Transformers-
Yeah, I have one from the first batches that came in France too (arg, the problem appeared in writing this message pfff)

I have the same problem, with stock rom.
Rebooting eventually fixes it, but sometimes several reboots are necessary.
After searching endlessly for a solution without any results, I thought about the touchscreen issues that I was having.
It occurred to me that the screen got particularly dirty very easily, was difficult to clean, seemed to register ghost touches, and (as odd as it may sound) the glass didn't feel very smooth. This is all in comparison to my iPad.
So... Even though I have heard mixed things about this, I took a chance and used some Rain-X on the touchscreen - works PHENOMENALLY!
After treating the screen and using the TF frequently for a week I have had absolutely no problems whatsoever. My TF screen is now just a smooth and responsive as my iPad and a hell of alot easier to clean.

Hi guys,
Last night after flashing a kernel my phone was stuck in boot loop..so I turned off the phone and connected to charge, morning I saw that whole night it was in loop.
Later fixed the loop issue, but now no matter which rom I am on the place where the icon dock is it flickers and has a shadow of Samsung logo I can relate this to the boot loop that caused burnt pixel.
If I keep brightness to the lowest it is not visible yet the moment wallpaper is a light colour and brightness is high it is visible, I want yo know your opinion is it a hardware issue or is it something that might go off with time ?
Regards
Arif

Yes. This hw issus.
when in startup time (bootlooping time) the lcd brigtness is max. So you have it whole night, it is very high possibility of lcd burn mark.
hope it can gone by time.

The screen is a little damaged, it probably heated up with the max brightness and the same picture, it will go away with usage by itself.
There are many apps that can solve this, they change every pixel to many colors very fast.
It will self correct itself
Hey thanx both for your response ..so far it seems that I got lucky and the flickering issue is gone after some hours of usage and rest
I have seen these issue on laptops and we have ended in replacing the lcd for the customers, flickering in laptop happens due to backlight issue, I was afraid that if backlight is gone I am axed as here also we have backlight as it's an lcd..so I think it was an issue of over heating that had left that mark and when it cooled down it become normal !

Has anybody noticed the following phenomenon? You look straight at the tablet while holding it perpendicular to the floor at your eyes level.
Then you start tilting it towards yourself - brightness fades at about 45 degree but then returns at about 70 degree and stays at the original level almost to 90. Same if you turn the tablet around.
I would not be surprised if the brightness was gradually fading as the angle increased, but this is the fact that it fades and comes back as the angle increases is what's puzzling me.
Not a big deal, I am just curious.

Color saturation is different when "the angle increases". I suggest you look into LCD polarizing filters. It's probably the screen component you want to investigate in order to understand this phenomenon.
Could it be the amount of light the ambient sensor is picking up? If you have it set to auto adjust that is.

I could not find that info related to tf700 screen... even generic articles on IPS and SIPS do not contain detailed description of how exactly brightness changes with viewing angle.

Nope, I have it on manual.
In case you have a tf700 - can you see this phenomenon, or it is just me?
I tried tilting while the screen showing a blank white page - same behavior, and it was almost like I could see some evenly distributed cloudy matter under the screen while at about 45 degree angle, and then the matter disappeared as the angle increased past 45...
resolved
OK, so I wrote Asus on it in get in reply usual "do a factory reset, if does not help - open an MRA";
I still insisted and got in reply something like "in this case we suggest you open an MRA".
I then visited a couple of stores and while I could not find TF700, I examined screens of TF101, TF201, TF300, Galaxy Tab 2, Acer, Toshiba - none had the issue.
At this point mine is going back to the seller.

HELP!
I returned my TF700 and got another one - and here we go, THE SAME issue - I tilt the screen - brightness fades at 45 degree then returns at 75 or so.
Dear FT700 owners, take a few seconds, share your experiences with me, I do not believe I am the only one having this issue.
ASUS folks, I would really appreciate if you chime on this too. If I return my second TF700 - I am done with ASUS tablets in general.
I went through blurry TF101, not working TF201, and now two TF700 seemingly having a display issue, and this is while the display is the main selling point of the unit.

My screen constantly adjusts brightness, but it has nothing to do with tilting the tablet. I can hold the tablet completely still and the brightness continuously adjusts, especially while watching videos. I must admit that it does get distracting as it happens every couple seconds depending on what is shown on the screen. I have autobrightness turned off.

Try cold boot, then try factory reset, and if no results - send it back to the seller.

That is the dynamic contrast that you are speaking of. Basically, the tablet increases and decreases the backlight depending on how much white is on the screen, etc... Annoying, but it also helps make the screen look good (super high contrast)... No way to disable it yet though...

What? Nothing is changing on the screen so it can't be what you are saying. If the screen is displaying STATIC content it should display the same brightness no matter how you are looking at it. As I said before in a previous post, it is manufacturing of the cheap screen. How else do you think Asus made the Infinity the same price as the Prime? They had to take shortcuts and use cheaper inferior parts. Sorry.
Saywhat? The poster that I was replying to said that it was most noticeble while watching videos, not while the screen was static... Of course it's not auto-contrast if the screen is static!
Please actually read the posts before making stupid remarks!

I use Vplayer and Diceplayer which have the gesture controls to max bright the screen and Volume control. When I'm watching a movie I set it to high and I never have an issue with it dimming. Try it out.
I think it overrights the light sensor.

So you are saying that you set the brightness to max and leave it there while watching a video?? I think that would be way to bright for most movie-viewing scenarios!

Oh man...I thought you wanted to understand the science behind the phenomenon, not that you percieved this as a problem.
This is normal. There's nothing wrong with your screen.

I also have a "brightness flicker" issue.
Even on a screen that does not change at all.
I just have to open google maps.
About every 2-10 seconds there are one or a few flickers.
I tried different power saving settings and disabled auto adjust brightness.
Screen still flicker.
I just have received my tf700t and have not yet noticed this flickering in other apps.
emmemm
this is normal, i noticed this too, when you go into a video it flickers and dims down but when you go back to the home screen it flickers back to normal, this is the contrast system not some bs about a cheap screen used by asus.
Ever since JB update, I started seeing this white screen freeze, and eventually reboot. It felt very random as this happened on occasions with different application; however, I have not had any for at least past 4-5 days, which never happened until I tried one thing. So I am somewhat convinced at least the issue on my end was related to a single application. And yes. in the past I tried cold boot, factory reset etc. none of them really helped. So I wanted to see if anyone else identified similar with other application. If so, let's list them here, so people would know.
1. Screen Filter
My white screen ended up happening whenever I use screen filter, which itself runs fine. But next morning, I turn back on the tablet after overnight charge, and open another application while screen filter is still on (from the night), that's when I see white screen. I can still use screen filter, but now I use it and turn it off before turn the screen off/recharge.
If you can get a video of the behavior, Asus would like to see:

Sometimes when I just surf the web or install apps from the play store, the screen turns GREY all of a sudden and the device becomes unresponsive and freezes.
I experienced this 4 times already.
I have not rooted it and run the official 4.2.1 Firmware.
I already made a factory reset after the third time it happened, but it keep happening.
is this a known issue or should I send in for repair?

I had that issue a couple of times when i was on ICS and i'm sure that other users also reported this but i don't know what's causing it.
I don't think you need to RMA the device,most likely is a software issue .
Are you saying the whole screen goes uniform gray? No pictures, no text, just one grey surface??
Or do you mean the screen dimming when a new web page is loading? The latter is a new feature of the 4.2 browser. Supposed to save battery which is think is boooogus.

There is a post "Transformer White Screen Freeze" that is similar. The only conclusion so far seems to be that it only occurs in portrait view no one matter what version of android or rom you're running.
Sent from my ASUS Transformer Pad TF700T using Tapatalk 2
That issue is software related and seems to happen on stock roms. It can happen anytime, often after rotating the screen from landscape to portrait. The screen turns grey with a black strip on one of the edges and after some seconds the device reboots.
I'm on CM for a week and I haven't had this issue again, I had it several times on stock roms including CROMi.
It's a graphical bug that only happens in Portrait mode. (Which explains why I have never seen it.) Happens to everyone on Stock. (if they use portrait mode, that is.)
This tablet was never actually meant to be a portrait device. (As evident by the location of everything...). Though that is ofcourse no excuse.
