Touchscreen consistently (and completely) unresponsive on wake up - Sony Xperia E3

Hi guys,
This problem has me stumped, so I figured I'd consult the hive mind.
The touchscreen works fine after the phone is turned on - be that for a continuous period of 30 seconds or 30 minutes. However, if/when it goes to sleep, the touchscreen becomes completely unresponsive on wake up. The screen turns on, rotates, and the physical buttons work fine. I figure no touch input is acknowledged, because if I tap the screen after it dims nothing happens; but if I press a physical button, then full brightness is restored.
I have been looking around for a solution for some time, but none of the three I found appear to be working, ie:
- Ensuring the Wi-Fi's set to be permanently on (no change on any of the settings)
- Changing the ROM (problem appeared in stock ROM, it now sports LineageOS)
- Changing the digitizer (problem is the same on old or salvaged screen)
At this point, I am not sure what else I can try. Any ideas would be most welcome.

Maybe charger? Some cables/chargers make touch panel go crazy (it used to happen to me with bad chargers) so try to change charger and USB cable.

AT&T Fuze screen issue - bottom menu-area of screen is flickering almost constantly

AT&T Fuze screen issue - bottom menu-area of screen is flickering almost constantly
(Forgive me for the length of this post. I am just trying to provide as much information as possible! If anyone has encountered this same or similar issue, your help is greatly appreciated).
I need help! (professional and otherwise) ...with my AT&T Fuze (rebranded Touch Pro).
I am developing a game for Windows Mobile called Scrobble (http://forum.xda-developers.com/showthread.php?p=3206316&posted=1), and I left it running overnight.
My screen is set to turn off after 1 minute, and my device set to sleep after 5 minutes when plugged in to external power.
I had the Fuze plugged into wall outlet power to recharge. I left it lying, like I always do, face down on a black soft-leather CD case (so the glowing charging light doesn't bother me).
I left it alone for the 7.5 or so hours I was asleep. When I woke up in the morning and picked it up, the screen was on. It usually is not on, and I don't think I pressed the button to activate the screen.
When I looked at the screen, the Scrobble program was still running, and the bottom menu portion of the screen was flickering. Scrobble has two menu buttons at the bottom -- "Turn" and "Game" -- with a SIP keyboard icon in between them (same as nearly all WM apps).
In any other program, or the Today screen, the menu portion of the screen flickers (the brightness constantly and rapidly fluctuates consistently... like a fluorescent light that is on its last leg).
I did a full power off and power on, and during the "world phone" screen and the the AT&T 3G "power up" animation, the flicker was -not- there. But as soon the Windows Mobile loading/splash screen appeared, the flicker returned, in the exact same spot.
And I can see the ghost "Turn -- [SIP] -- Game" menu in the flicker. But I don't think it's burnt into the display, because it's not there during the first two loading/splash screens.
Currently I have the battery completely removed from the device and will leave it out for a while. If that doesn't work I will do a hard reset.
Any help would be greatly appreciated!! (This device is about 2 months old -- does HTC provide any support for it directly?).
Fixed
Phew! My screen flicker issue is no more.
I'm not sure if it's because I took the battery out and let it sit and think about what it had done for ~22 hours, or if it's because it just went away after a while (with the battery out for 22hrs). But either way, my Fuze is back to normal!
So if anyone leaves theirs on overnight and wakes up in the morning to a flickering ghost of a menu at the bottom, my suggestion is to fully reboot it, then take the battery out and leave it out overnight!
(It's kind of nice going a full day without any phone calls!!).
good for you.. you dont need a new phone giving you damage issues already... glad to hear that its gone
Thanks you for this post. I am going through the same thing with my ATT Fuze. This time it is Tomtom that I left running overnight with the screen turning on and off. I can add that the flicker and ghost is there the second the phone powers on. I have already hard reset and took the battery out for a few mins, but the flickering still there. Now I will take the battery out for several hours and hopefully it will be normal again.
I had a similar issue this week. I was using the phone all day, getting emails and phone calls, no problems. I get home and go to charge my phone and it doesn't appear to be charging. I flip on the screen and the whole screen is flickering on and off like it's not getting enough power. I charged the device over night, hard reset, pulled battery for 24 hours and still it won't go away. I just got the device thru amazon so I already reordered a replacement.
I've never left my screen on for hours at a time and I sometimes run into that same issue. The bottom of the screen flickers, and I can see a ghost image of my left and right soft keys when doing things that pull up a dark grey or black screen, like adjusting the volume. I usually try a few soft resets, and if that doesn't work I turn it off and take the battery out for a while. From what I am reading it seems to be correlated with extended periods of screen usage, but my screen has rarely been kept on for more than 30 minutes at a time.
Not to beat a dead horse or anything, but I was just having the same problem with my Fuze: the bottom quarter of the screen was flickering, but without the ghosting you spoke of. Out of curiosity, I went into my "Power Settings" menu, and for some reason the "auto adjust backlight" was unchecked, and the brightness settings were maxed out. I checked "auto adjust backlight" and the flickering stopped. Not sure why, but thought I'd add it to the thread.

Yeah I did notice that it's only really noticeable when the screen is set to max brightness. Setting it on auto adjust cleared it up for me also.

thx guys...helped me out too...
Just sent my unit in for repair (under warrenty) due to the screen flicker issue, lets see what happens when it comes back.
I just started to experience the flicker today. Has be somewhat concerned. The device is only two weeks old.
However, it seems to have stopped by itself while I was searching the forums for an answer. If it returns, I'll try the 'remove battery' method and see if that helps.
Also, I love Scrobble! Shame it doesn't work on QVGA displays. Or, at least, didn't on my Wizard...
Related thread
Hey guys there's a thread with the same exact issue and a screenshot on the first post.
http://forum.xda-developers.com/showthread.php?t=535099
Seems to be something related to the Hardware 3D Acceleration driver for Windows Mobile, I get this problem only once 3d has been activated.
If Sense/TF3D is turned off, I never see this problem. It only comes up once a game or Sense has been launched.
I can also boot into Android without 3D activated and not have this problem, but if I run Sense then go into Android I get the flicker from a Windows Mobile screen while in Android.
protwitness: That doesn't seem to be the case (for me, at least.) I don't run TF3D and it still happens. I can't really discern what the trigger is, but I have a feeling it has something to do with the screen brightness auto adjustment. (Sometimes, I'll turn my phone on when it's dark and it jumps to full day-light brightness for some reason.)
I've adjusted to it and it doesn't really bother me any more.

[Q] Backlight Issue with Brightness Scale

I am having an issue with my TF where I cannot set the Brightness scale to anything but "Auto" - if I attempt to manually change it, the backlight turns off and the only way I can get it back on is to plug the tablet into the charger. The unit then jumps up to 100% brightness, but if I unplug it, the backlight turns off.
When the unit is plugged in, I can move the brightness scale and can see the screen dim and brighten as it should...
I have the latest firmware (8.2.3.9)... any ideas???
Some more info... if the backlight turns off, I can do a reset of the device by holding down the power key and then turning the unit back on. The startup screens do display properly, but when the device comes up, the screen darkens again. You can also make out the time and see some transitions between screens very faintly... its just the backlight that is off, everything else works fine.
The screen illuminates properly once again when plugged in...
The fact that the startup screens (the Asus and eee pad title screens) illuminate properly leads me to believe that this is a software issue. Help!!
Addendum: It appears I CAN adjust the brightness scale without being plugged in somewhat... the backlight turns off if I attempt to slide the brightness scale above 2/3 full brightness or so... anything lower than that is fine (or 'AUTO'). But, again, if the device is plugged in, FULL Brightness is possible.
This is very frustrating... I don't know whether to RMA this (who knows how long this will take), return to BestBuy (who doesn't have any units), or wait for a possible software fix??

ive seen one othet person reporting this problem,
since its not a common problem,
your best bet is to RMA it.
dig in in the forum snd see what the other person did.
what did you do to get this issue sorted? I have the exact same problem whilst running a rooted Transformer running Prime 1.5
Same problem here
I just started having the same issue, too (stock ROM). Tried factory reset, but didn't help.
Has anyone else found a solution, or should I just RMA?

Need help identifing reason for strange and frequent freezes

Hi guys
I have this strange behavior going on in my Sentation.
Out of nowhere my phone started to have strange screen behavior... Didn't light up after pressing the power button (had to phone my self in order to get screen on).
The next thing was that suddenly the screen goes to maximum brightness or goes to minimum without any explanation (tried both auto brightness or manual).
After that I noticed that the screen went off when I was using it but when I pressed the left side of it it lighted up and off again... making me think of some kind of bad contact underneath. As I already had changed a broken touch screen for t3 times, and let the phone fall for several times I thought it had to do with some plug out of line...
I disassembled the phone completely and mounted up back again. The thing is that the phone started to freeze every 5 minutes (screen on but completely freezed. I have to pul out battery). Sometimes it freezes even in the recovery menu. I've tried several rom's with full wipe and not installing anything and its all the same.
Some times I still not that the screen goes off during the freeze but when I touch the left side it goes on again, but that doesn't change the freezed state even that I let down the phone for several minutes.
I disassemble the phone again, tried different back cover and different battery (one stock and other extra strength) I tried also all the suggestion related to the small pin in the back not connecting well with the back cover (adding an aluminium foil, pulling the pin out, etc..)
Nothing seams to resolve anything so I have clearly an hardware problem... but I don't know what to replace or where to look the damage!!!
Can anybody help me please?!
Update
I have an update on my problem:
I noticed that when I leave the phone on top of some kind of metal part and don't touch it it works all day without any problem but, as soon as I start to touch the phone, it freezes within minutes!
Could it be some kind of static electrical problem? How to resolve it?
I would apreciate any help
Thanks

[Q] screen wierds out

I've had an odd problem with my 820 almost since getting. I'm hoping one of you geniuses have some advice.
When I turn it on it works perfectly, sometimes for hours. Then the screen goes blank, and then random pixels begin to appear, starting at the top of the screen. Outdoors rather than random pixels the screen goes almost totally green. Strangely, if part of the screen is obscured the green only covers rhe exposed area.
Pressing the on button repeatedly usually brings back the lock screen and reset (on+down) fixes the problem for another few hours.
By the way, eventhough I can't see the screen the touch sensor works. For instance I can hold theon button and then swipe downwards to turn off the phone. I can also answer and hang up using earphones.
My daughter who purchased the phone said it worked fine until the amber update. I had hoped the black update would fix the problem but no change. I found some posts from people with the same problem who sent the phone in to be fixed and got it back in the same condition. I really don't want to go through the hassle unless I expect to get it back fixed. I'd rather try fixing it myself.
My question is whether this is a firmware problem an whether it is likely that re-installing the stock black rom would do any more than the ota install that occurred automatically did (or didn't do).
Any ideas?
Nobody?
By the way it seems to happen only, or mostly when in standby.
I installed an app that displays a clock and doesn't allow the phone to go into standby mode,
and the problem doesn't appear to occur (unless I forget to leave the app on top).
I would set the phone to standby = "never" but the option isn't available on my phone, though
I understand that there are those with the standby = "never" option.
Any idea if I can set standby = "never" with keyboard commands, perhaps?

TF101 does not display on screen (through hdmi output works fine)

Hi,
my name is Josemari, from Spain.
I have a TF101 with dock (and original rom from Asus) that does not display anything on screen since a soft fall from 10cm (daughter in a very very small chair).
When i plug the charger, it works (and beeps -charge-). When i plug the dock, also beeps. When i connect through hdmi output to my tv, it also works. I can use the tablet perfectly with my fingers.
What can i do?
I disassembled the tablet and i checked all conectors, but i do not see anything wrong.
Thanks.
I had the exact same problem. Even though it has fallen before without a problem, in my last 2 cases it was a loose connection for the video screen. I had to open up the tablet and simply push the video connection back on all the way. It's rather easy if you're familiar with taking things like this apart. Make sure you are careful when you re install the side trim that holds the buttons. It's easy to break the red tabs that press against the buttons. It may be helpful to you to look up a disassembly guide. I believe if you google the specific issue you will find pictures. Again it's been a long time. Hope this helps
I have the same issue since a few days.
Difference here, when I boot up (holding power button until reboot) the screen is on (Asus logo and boot animation)
The display goes balck / disappears (backlight off) when the lock screen comes up.
Checked the inner display cable and connector with no success.
Did a factory reset and it was working again, until I changed the brightness to a higher level. Then the screen was dark again.
I managed to change brightness to a lower level using the working HDMI interface. After that I switched the tablet off and on and the screen was lit up again.
Another effect: when power adapter is plugged in, I can go to a higher brightness level until the backlight turns itself off.
It looks like a hardware defekt of the backlight electronic to me. Couldn't find any spare parts, such as backlight inverter, though.
Can anybody confirm this or knows how to repair?
I will use it at 30-50% brightness now and see if it gets worse over time.
