[Q] Touchscreen re-calibration?

[Pyperkub]

Hi all - my TF700 has been solid for about 9 months, but this past weekend the touchscreen started getting wonky and now it will work for 5-10 seconds and then not register any touches, until the power button is toggled to put it to sleep and then wake up and go through the process again. In my research, it appears as if this can be addressed through recalibration of the Touchscreen.

However, I don't even know if that's possible with my current stock/rooted setup. I did try booting into recovery, but I saw the RCK/Android/Wipe Data prompts, and didn't want to go anywhere without knowing what each would do. I'm guessing maybe the Android button, but I'm not sure.

Is there an easier way to recalibrate the touchscreen without doing a factory reset, or going to a new ROM yet?

Thanks!

This may be a hardware problem with the digitizer going bad. I would contact Asus, they probably will recommend a factory reset and you should try that anyway.

But a custom rom will not take care of this problem - at least I do not think this is software related....
Good that you are still under warranty!

FYI:
RCK will boot into the stock recovery which will not do anything unless you have an update file downloaded somewhere on your storage - it'll just show you an Android falling over with it's belly open a ! triangle. Scary if you don't know what it is! LOL

Android will boot you back into your system. This is a so called 'cold boot' and you could try that. I doubt it'll help, but it won't hurt either.

Wipe Data does exactly what it says. You better have everything you care about backed up before you execute that command.

You use the Volume Down button to navigate between the icons and the Volume Up to execute.

Hmmm. after enabling Developer mode (so I could d a Titanium backup), I decided to enable the touch sensing, and what I've found is that it appears as if there is a spot in the northeast quadrant (while holding vertically, with buttons on the right/dock connector on the left) that gets stuck in the 'touched' sense (the little dot sticks, and in the kindle reader, it acts like the text is selected).

Sometimes it gets unstuck when pressing the power button to sleep, and then re-logging in via the lockscreen code I have set. Sometimes it doesn't. I guess I'll contact support and see if I can capture it on video with my phone.

Pyperkup,

Did you ever resolve this issue? I'm experiencing the Very same issue on my TF700T.

Thanks

Had to send it in on warranty.
