[resolved] Problem turning on the screen with touch - Google Pixel 4a Questions & Answers

When I wake up the cell phone it gives a bug
I have this problem I don't know why
I thought it was the September update, but I installed the October patch and the same thing happens
I think it's root. Has anyone had this problem? Do you know how to solve?
I've already tried changing the unlock type
Video of what's happening

This problem only does not happen when I leave the option always display active
Edit: I just installed the clean flash from the rom stock and it still has the same problem
resoved:
well i think i figured out what causes this bug on the lock screen. I tested several things, uninstalled LSxposed, root, applications etc. But nothing solved. So I put in gesture navigation as I only use buttons. And that was it, after I put the gesture navigation there was no more problems

[Q] touch screen malfunction

hi,
I'm not sure when exactly this issue started on my phone, but I updated my touch pro with the chevron updater and have quite a lot of apps installed.
after several seconds workling with the phone, the touch screen stops working while the phone acts perfectly normal. I can use the keyboard and tilt the phone but I cannot use the touch screen anymore.
By turning the phone off and on it works again.
has anyone experienced a behavior like this?
I noticed my touchscreen becoming unresponsive when loading particular websites. Even had it freeze once (only time it ever froze on me)
What were you doing when it does this? Do you have the multitasking reg edit on?

I know this is an old thread but this is the only reference to the exact same problem that I'm having. I'm having difficulty putting this down to hardware as the screen becomes responsive again when locking and unlocking which might point to software.
It could be a hardware issue that is resolved by locking then unlocking the phone but I don't know enough about the construction of it to have an opinion.
The advice I've had from htc is to wipe the 'phone and start again but I don't expect that to solve it (especially as their call handling system refers to Window Mobile 7 - the second large commercial organisation I've seen that on in recent weeks without looking too hard!).
Has anyone else seen this since the original post or @exilkubaner was a solution found to your problem?
Hi,
I have exactly the same problem. I hard reset my HTC 7 Pro, but no success, my screen doesn't respond until i lock/unlock the device.
So, any one have resolved this issue since the first post ?
Regards
Had the same issue, but I didn't have any roms installed.
Brought it in to Sprint and they found that I had a fried ribbon connecting the screen to the phone. Replaced under warranty.
It happened again, I determined that it was caused by my click in belt clip/holster. When I pull the phone out, it pulls the screen away from the keyboard a bit.
^Wow. Nice find. I'll have to be careful with mine now as I could easily run in to the same problem pulling it out like that.

Screen backlight stays on!

Hello!
My oneplus one is having this issue for a while now, When I plug it in and lock the device, there is a 60~70% chance that the display stays on but its just blank, I have to unlock it and lock it again to fix it.
Recently this also started happening when it was not charging and the screen would often stay on causing massive battery drain :/
This happens on every single rom all the way from CM11S up to CM13 and also oxygen os,...
Does anyone know what the problem is?
Thanks,
Noahvt
I have the same problem since I can remember, also looking for an answer.
I have a similar issue. Sometimes the screen stays on, but is dimmed. A simple double press of the power button resolves it (turn on full, turn off screen) but its mildly irritating. I have only noticed it since being on sultanxdas cm12 ROM. I had an issue with a notification LED app not working since a recent ROM update so uninstalled it. Maybe the issue was related to that app as I cant remember the issue occurring since I uninstalled it a few days ago.

Gravity sensor suddenly stopped working

Hi, it appears that recently the gravity sensor in my Nexus 5 stopped working.
At least it is what it seems by using sensor testing apps. And this makes it impossible for the phone to get its orientation (compass is not working).
Screen rotation is still working fine though.
Here is what happened exactly: not long ago I was using Google Maps, but the phone was a bit sluggish so I decided to reboot it.
After rebooting I opened Google Maps again and immediately noticed that the orientation indicator was missing (the blue "beam"), while it was present before the reboot. But I didn't care about it, and just thought that the compass needed re-calibration.
After a few days the orientation indicator was still missing, and the phone never asked me to re-calibrate, as it used to do before instead.
Then one day I launched Google Sky Map, and noticed that the view does not rotate automatically.
So I fired up a sensor test app I had installed (asd.vector.sensor), and no data is displayed for the Gravity sensor. Also orientation is not displayed and the info says that the gravity sensor is used to compute orientation, too.
Other sensors are ok, and as I already wrote screen rotation still works great.
Any clues about this issue? Did anyone ever experience this?
I'm afraid a system restore would not help...
I'm using Resurrection Remix ROM, Android 6.0.1.
Thanks.
If the problem exists on a stock ROM, it could be a hardware fault.

Ok yes, but I still do not know if it exists on a stock ROM.
Taking it the other way around... Do you think there is real possibility that it is a software fault?
I mean: did it ever occur to anyone? Is there really any hope that resetting my phone to stock will fix this?
I HATE having to reset my phone...
Thank you.
I stopped using custom roms a while ago because of minor problems that would suddenly appear.
I don't think there is a way to really tell if it is software or hardware unless you reset or use a stock ROM.

Well, that's a little hope at least.
I will need to find some time to re-stock my Nexus and try.
Thanks .
Ok, I restored the phone to stock and all sensors work again now!
Thanks audit13 for pushing me in that direction .
That's great that it was a software bug in the custom ROM.
Now you get to hunt for a custom ROM that works with a minimal or zero number of issues

Mi Note 10 weird screen issue (ghost touch?)

Hi all,
Just got this Mi Note 10 today and while setting up the phone I started to get those weird screen touches..
Happened so often that I enabled 'Show Taps' via developer options and recorded it here:

>> Is there anything I can do about this? Not sure if this is a Hardware or Software fault?
Any thoughts welcome!
thanks

Okay, this is weird. Which version is it? And did you have already tried to reset your device? If it's still there it's probably a hardware defect.

Well, I had the same MIUI version and region. I bet it's not a software problem. Just send it back

Right, so no fix really... disappointing as the cameras are impressive
My device came shipped with Android Pie Based Miui 11, no screen weirdness. Just after the Android 10 updates that ghost touches appear. So I guess it's just software bug.
me too, sure software problem.
Thanks for the feedback, if software-related were you able to roll back to fix this?
Happy to try a workaround as I'm very reluctant to send it back..
worth a try though, but unfortunately Xiaomi didn't provide stock ROM specifically for my region so I left with no choice
Completely puzzled as I did a Factory Reset via Recovery and haven't seen the issue for past 2 days, I've left the screen touch tracing on and no 'ghost touch' was recorded..
so I don't know what to believe anymore, got an open return ticket but would hate to send it back without needing to..
how can I make sure issue is gone?
Hi, i had this problem 3 weeks ago, temporary solved with hard reset, worked perfectly until yesterday night when this problem went back.
Hard reset again, problem still there.
Someone solved it permanently?
It is really weird because, if i turn off/on the display, sometime works sometime not :S
The phone came with Android 9 and I started to face this after updating to Android 10. The issue is not extreme as shown in the video, it just the touch becomes slow to respond and hard to type fast with the keyboard. Turning off the screen and turning back on solves it temporarily sometimes.
I tried disabling on screen fingerprint and the problem seems to be reduced now. Definitely a software bug
I'm using Mi note 10 lite it also has same problem. Sometime touch freezing and after press power button automatically fix. Some time need to restart. And also one person told me he is fixed by this issue by turned off fingerprint sensor.

I have the exact same problem as you, slow to respond and hard to type. Need to apply more force on the screen for it to respond. This happened randomly throughout the day but are more common during night time for me.
I think it has something to do with the screen lock pin or fingerprint, by changing the screen lock from ie pin to pattern or turning off fingerprint print seems to temporary fix the issue. Another solution is to reboot the phone. I'm using Note 10 Lite btw.

I am using the Pro version. Looks like this issue is common for all the phone models in the Note 10 series. Yes, I have noticed that this issue often happens at night.
Try switching off MIUI optimization under Developer Options and restart your device. Then switch it On and restart again. This workaround solved my issue.

This fixed the issue for a few days and it started to reappear again. When the issue appears, if I turn on Game Turbo for any app (eg: WhatsApp) that particular app doesn't have this touch issue. Looks like a software optimization or battery optimization of MIUI is causing this issue

What firmware version are u in?
I'm currently at 11.0.16.0 and fortunately this issue did not yet reappeared after the workaround.
This is definitely a software ISSUE with MIUI.

MIUI 11.1.3.0 Global Stable
Will try out the MIUI optimization to see whether issue still arise. I'll see if my game turbo have the same issue as you too.
I'm currently at 11.0.7.0 (Mi Note 10 Lite)
Edit: Mi optimisation doesn't work for me but the Game Turbo trick do work.

Touchscreen Issue. Two taps becomes a swipe.

I'm having this problem with my NEW mi note 10 phone.
I notice it when first when I'm typing on my keyboard as usual speed.
It kept doing this phantom swipe across two finger taps.
I posted some videos to illustrate my problem.
Is it a software or hardware problem? (This problem is intermittent as well so it's really hard to pinpoint it)

ttps://drive.google.com/file/d/1-6M1e33Qxz8HXckkcLb3sWVTXG6fPHzv/view?usp=sharing (Using touchscreen tester, you can clearly see the phantom swipe across the two taps)
Anyone else having this problem except for me?
When this problem comes, I can't even properly play a game.
reformat factory reset - fail
reinstall latest miui global 11.1. 2 - fail
optimise animation all off - fail
gboard - fail
xiaomi keyboard - fail
SwiftKey - fail
turn off Miui optimization - fail
restart phone - fail
clear ram, clear cache, clear recent, speed boast - fail
CPU slowing down due to background processes?
Touch digitalizer got problem? (I tried shaking it gently, poking it but it does not affect anything at all)
As I said, this problem is intermittent. There are times when I can use it without any problems at all.
It's really weird.
It can be totally fine one moment and then it acts up again.
There's another thread about this. Most of us face this issue on all variants of the phone (Pro/Lite). This started with April or May update where Mi added a edge sensitivity control setting.
What happens here is that touch sensitivity suddenly reduces and it will be hard to do anything that involves rapid touch such as typing.
Lock and unlocking the screen or restarting the phone will fix this temporarily. There's no permanent solution.
Also when this issue occurs again, go to the settings and turn on Game Turbo for an app such as WhatsApp, without and then try typing on WhatsApp, you will see that the issue is gone.
We all are waiting for Mi to fix this. But I would advice to return the phone if it's under warranty though this is a software issue
