[Q] Screen unreponsive after wake from sleep

For some reason the TF touch screen is completly unreponsive after some wakes from sleep. not always though. thankfully the keyboard works fine so after a reboot all is well.. anyone have any idea why?
I've been having the same problem since day #2. The screen does not respond but the if you rotate it the orientation will change. What I was doing was turning it off by holding power button and after rebooting it would be working. Unfortunately this stopped working. Now, even after a boot it doesn't work.
I'm considering returning the eee pad to best buy and getting my money back.
I saw a thread about this in another forum (But I can't post the link ...sorry). Basically it was attributed to the latest patch and it's seen in people who don't have the keyboard dock so it would not "complete" the update

[Q] Slide2Unlock problem + touch screen not working

Hello guys,
I got in trouble with my Polaris. I'm more then 1 year running ROM from Salvy (megan3)
Today my touch screen stopped reacting and unfortunatelly I'm in a lock mode, so to unlock my device I have to slide the button (that is impossible becouse of the not-reacting touch screen).
I tryed soft reset several times, did not help.
Calibrating the displaycould help to get my screen working, but how should I get to this if I'm not able to unlock the screen?
I'm afraid to do a hard reset becouse I'm not sure if the touch function of the screen will work (to calibrate the display) - i could get stuck on the calibrate display step of hard resetting.
So any advice how to get my polaris work?
Thank you for comments.

[Q] Unresponsive touch screen

So I have a problem with my CUBE U30GT-H. I bought it almost 3 months ago, all have worked very well, but now touch screen doesn't.
Problem occurs when I have to unlock screen, it simply doesn't work after sleep. But when I restart it works again, tablet totally works with my mice. I tried to wipe cache and reinstall firmware, but nothing changed. So i think it will be a good option if touch screen doesn't shut down when tablet put to sleep. I was searching for a touch screen config, but didn't find. I hope you can help me with problem and give some ideas.
Now I use this firmware Evolution JB 1.0.2 ( flashmyandroid.com/forum/showthread.php?1192-Release-Evolution-JB-1-0-2-27-08-2012 )
P.S. I am new on this forum so I don't know where to put this question. sorry...

Touchscreen becomes unresponsive from time to time.

I have a Huawei G510, I've recently posted a thread talking about a problem I had with capacitive buttons pressing themselves but i got no reply, I managed to get it fixed by disabling them from android file Generic.kl and qwerty.kl
and enabling softkeys. But now i have another problem with the screen it suddenly becomes unresponsive but after i lock the screen and unlock it it works, and I have to do this every minute or less. I have done a factory reset, wiped cache and everything but it still occurs.
Any idea about what causes this ?

Amazon fire hd 8 (7th generation) problem pls help

Hello , I had this problem for a long time now and I have looked for a lot of possible solution and none worked with me
I was watching a video normally when suddenly the screen stopped responding to any touch I tried holding on the power button to restart it and it did restart but the problem is still there , I even tried factory reset which you can do only with the use of the buttons ,and it also didn't work .
I have disconnected the battery and reconnected it and nothing also
the problem went worse when I disconnected and reconnected the screen digitizer or what I think it is . the screen went off totally , there is only the sound , the sound of the tablet starting and also the volume buttons make a sound when I press them as I think it's the sound going up and down .
I don't know what is exactly the problem , but I'm sure disconnecting the screen digitizer made it worse so take that in mind .
I hope there is a fix as I can't get it back to amazon ,thanks

Seems to me that your hardware is damaged, replace the hardware with new parts, then reflash your stock firmware. Then flash TWRP and root the device.
