Screen not turning on sometimes - Google Pixel 2 XL Questions & Answers

Has anyone has an issue where the screen won't turn on after using the fingerprint sensor? I can feel it unlock but I sometimes have to hold the power button until the power off/reboot menu comes up which then starts the display up from being all black. Have Magisk beta and Xposed installed so maybe that's the issue?

Is AOD on or off? What happens when it's on?

AOD is on. So what happens is if the phone is on my desk and AOD is showing time, it'll show the notification briefly then just go black(nothing is covering proximity sensor and notification light is blinking). I then usually have to either do the power menu trick I mentioned or just restart the phone. If it's in my pocket on the other hand I'll pull it out and it'll be black with a notification light.
Oddly enough it usually only occurs with Snapchat so I think it may have to do with having snaptools installed?

Quite possibly so. I know nothing about snap face, snap chat, or whatever these social media apps do. Although, you may try clearing the app data and cache on said app to see if it helps. No guarantees though. As is the case with many things android! ??

I've had the same issue ever since I installed, I believe, the nav bar immersive mod. Not sure, around same time. I was able to hurt power button twice for camera and that would pull it up and u could switch back to screen. I don't have xposed or Snapchat, so I don't think either of those are it. It's random when it happens to me.

I've had similar issues. I'm not rooted and have never used Snapchat or AOD. I do use immersive mode for some apps so I've thought that might be causing it. Like stated above, I can get the screen to come on my double tap to open the camera or just holding the phone face down and tap the back a couple times then flip back over and the screen comes on.

I'm also having this issue. Ambient display seems to prevent the issue for me. If I reboot the issue is gone for a period as well. Not rooted but have immersive mode acrive via nav bar hider.

Ok so a little more testing. When Ambient display is set to always on, I have no issue, maybe a slight lag when waking/unlocking. When ambient is set to tap or pick up i get issues, when ambient display is set to off at all times, i have no issue. Plugging the phone in to charge seems to force the issue to happen.
Edit: Seems that even with ambient display off totally the issue pops up. Strange thing is if i unlock the phone and take a screen shot, its totally black.

I to have this happen and like sportytony I use camera to wake device. Sometimes that too takes a bit. Most of the time when it finally does wake there will be a notification that systemui isn't responding. So I wonder if it's related.

Ok, I've been having this issue happen multiple times a day. I use this immersive app: https://play.google.com/store/apps/details?id=in.tsdo.elw
Since I have turned all ambient display options off and made sure that System UI is unchecked in the immersive app i haven't had an issue at all.

Its definitely related to system UI, com.android.systemui to be precise
i used to try to set up Power Nap on this device, but it can't find System UI in app list, make me unable to whitelist it, thus causing same issue like yours,
Screen wont turn on after sleep, since System UI wake up is blocked

I was using hide navbars and had this issue
I uninstalled and never had that problem again

Didn't expect all these replies but I'm going to try to untick system UI and see what happens. Thank you all!

Difficult to turn on screen in dark

Has anyone else noticed that when in a dark area, pressing the main button will turn on the screen but it will then automatically and immidiately turn off?
Several times I've gotten into a battle with the phone only to lose, turning it on and it turns off, then turning it on again and so on...
To compound the issue, in these situations it seems that double tap is signifigantly less responsive to activate the screen as well.
I'm pretty sure this phone is using some sort of facial recognition, it has smart stay doesnt it? I think it has gravity/accelerometer to turn on the screen when you pull it out of your pocket. In the back of my mind I'm thinking that since it cant see me it is shutting off but this doesnt seem consistent...
I'm running stock rom, rooted with twrp. Any ideas?
I have not experienced that. Did your G3 do that out of the box?

Never heard of it. Screen is set to auto off in 30 seconds. Change it to 2 min and you should be good. If u running without a case then maybe the hand is touching the edges of screen this will also shut screen off in double tap.

I didn't notice it until the last week or so. but I kind of feel like that was because I hadn't used the phone that much up until then. I didn't make any major changes to the phone immediately before I started noticing it either, I had already had it rooted for about a week. I feel like the stock rom does have some glitches to it.
The G3 does have a "smart screen" feature that detects your face (Settings > Display). Disable that and see if it helps.
I've not run into this in the dark but have when I try and use my arm band holder when running. The holder covers the ambient light sensor so the phone thinks it was accidentally turned on like in a pocket and shuts right off. Super annoying.
Noticed similar behavior when the phone is in my bike mount at night. Basically it's acting like the proximity sensor is covered. In my bike mount's case, it is covered by a clear screen cover, but normally that doesn't trigger the proximity sensor. But when it's very dark out (not under a street light etc.), it seems to think it's blocked and turns itself off. Annoying.

Tried but remains the same... This was the only thread I found concerning this.
Ive had this issue too investigating now
Had that issue when I was using the lock screen face unlock. In the dark it didn't see my face and then it shut off. Setting is in lock screen section

Lol.
I have the same issue EVERY night. Why is that? It's very annoying
Same issue here
it seemed to resolve itself when I factory reset my phone
but after I got my apps reinstalled from my google backup it started again
so it seems like it's a software issue - not sure to which app it is related to
let me know if you find a fix - this is quite annoying
Me too. I've been facing this issue at night, when it's very dark.
Me and my buddy were in the car during a roadtrip and it was very dark, I mean like: No lights outside, no lights inside the car, the double tap feature didn't even work to begin with and whenever I tried to use the "Power Button" It would come on and then suddenly 'boom' Turn off, now this would happen a few times until it stays on. Weird...
I just experienced this myself, first time I've seen it happen in the 30 + G5's that I've sold. If it's in the dark it just doesn't turn on at all. I hope LG is fixing this. I'm about to Factory Reset it right now and hope for the best! Someone else mentioned that this is the only forum that is disccusing this issue. It must be a very few that are effected. I'm testing another one as we speak.
Has this issue been resolved? My friend's G3 also has this issue. Day time no problem. When it is dark the screen wont' stay on.
Same problem, no fix yet
Same problem here - Pointing it at any light and pressing the power button will turn it on. (As will plugging it into power). Tried tinkering with all sorts of settings (face recognition/auto dimming feature/etc) nothing worked. Tried factory reset, that didn't work either.
My issue started after i had my screen replaced (by a shady shop) who probably didn't do a good job of packing it back together....I'm going to see if I can have someone open it up and clean it out a bit..
I have the same issue on my G3. Even if you're under the covers in bed, the thing doesn't turn on until it gets light. It basically doesn't turn on in the dark through double tap and actually not even with the power button. It could become a safety hazard for someone in an emergency situation.

Screen turning on in pocket, causing poor battery life?

I realized today my phone was facing inwards towards my leg and that it may be double tapping and turning on in my pants. Any way of stopping this, but also monitoring? I am just curious as I faced my phone outward it kept my battery lasting much longer today.

I had the same issue, but for me it turned out to be neither the back button nor double tap to wake. For me it was greenify, which does evil things when it doesn't have root: it turns on the screen, goes to the app info of an app it wants to hibernate, and "clicks" the "force stop" button, before going back and just leaving the screen on.
Of course this may not be the cause of your problem. You may not even have greenify installed. Have a useful way to debug the issue: install tasker (or something similar, maybe condi can do it too), and make a profile that makes your phone vibrate when the screen turns on. Make sure the vibration duration is distinguishable from notifications, 200 ms worked for me.
This way, you will know exactly when your phone turns on in your pocket. You will be able to reason about whether the back button was accidentally pressed or whether it's double tap to wake, or something else altogether, like greenify in my case.
Just a side note: it's unlikely to be double tap to wake, because double tap to wake will not turn your screen on when the proximity sensor detects that something is close. You can try that by holding your finger over the proximity sensor while trying to turn it on. Double tap to wake won't turn the screen on in the first place, and the screen will turn on and immediately off when using the power button.
So yeah, try the tasker/condi profile and see what your phone does right after it wakes. I saw mine force closing Facebook messenger like 7 times in less than an hour, and it stopped after I uninstalled greenify.

Ive noticed the screen on out of pocket but rarely. One new feature is the "slide down" quick peek while the display is off. This new feature may have new side effects.

That too doesn't work when the proximity sensor senses something is close. Try it by holding a finger over it while trying to pull down the thing with another finger.

(Issue) Long delay to turn on display from sleep

Since upgrading to OOS 4.1.6, when leaving the device asleep for awhile, the display will not want to turn back on. The phone will vibrate for double-tap or fingerprint, however I have to wait about 10 seconds for the screen to actually turn on reguardless if using power button, double tap, or fingerprint.
- I have tried pocket mode both off/on did not work

Of course I rebooted already, that's the most obvious first troubleshooting step. I've now uninstalled Greenify since it's the only thing I can think of that has a screen lock feature so I'm trying that now.

Naptime / Force Doze can be an issue. Especially if your screen is off for a longer period of time. With Naptime you can disable the fact that it will stop your sensors. Might be worth to check out!
The issue seems to be gone after uninstalling greenify. If anyone else has this issue I suggest trying that. I'm not sure if it's a greenify bug I had or because my very dirty flash from OOS 4.1.3 -> 4.1.6. I had many freezing boots and flashed it almost 10 times before it worked.

Question OnePlus BlackScreen after PhoneCall

Hi,
I have a problem with my OP 9Pro.
After a phone call, the display sometimes stays black and it takes a while before you can use the device again.
Does anyone else have that and, above all, how can I solve the problem?
Many greetings and thanks
Mars
Are you on OOS12? I only experienced that bug in the short time I ran OOS12. One of the main reasons I reverted to OOS11 actually.
Yeah I get this too. From what I can tell, it seems to have something to do with the proximity sensor killing the screen when you put it up to your ear, then hanging when the call ends.
OOS11
Me too. On 11. Thinking it may be from Nova or Adguard. Until I figured out that I could hit the "screen on" button to regain control I would wait till the other person hung up. So, as a workaround that's what I do, hit the button.
That happens when the proximity sensor it's being blocked. If you have any screen protector over the camera notch (where the proximity sensor is) then that's why it's turning the screen off.
If you don't have anything covering the sensor then try making a call on another app (like WhatsApp) to see if the issue persists there too. If not then it might be the dial app, try restarting your phone.
If it happens on many messaging apps, and there's nothing covering the sensor, try downloading a sensor tester app to see if the proximity sensor is being triggered all the time. If it is then it's a hardware issue and you'll have to return your phone a get a new one.

Power button is unresponsive when the phone goes pitch black. Even switching the alert slider to something different doesn't trigger the fingerprint sensor on.
I'll try disabling pocket mode. I also found positive feedback about this when you enable the "Override force-dark" setting in Developer Options. See if that helps.
Has been happening to me from time to time since A12. I just hold volume up, volume down and power button at same time and reboot to recovery and restart from there. That fixes it really quick for me.
Yes, I'm on A12 because I thought it would get better here. But I had the same problem with the A11.
I haven't managed to solve the problem yet.
It also happens on Android 11 but it's not quite as bad here. The display turns on after a little while.
Where is the sensor actually? It's not the camera. It's to the right of the speaker. or?
Hi, Guess!
I got a solution from the Oneplus team. (1800 202 8888) / general phone tech support team helped me with these steps:
1- under setting search reset
2- click on Reset all settings
3- Reset all settings. click it.
As this is a normal reset will not lose your data.
The last option is if this doesn't work then we have to backup all data from the phone and do a factory reset.
or it's a hardware issue.
e-regards!

Question Camera no longer working

Is anyone else experiencing their camera app no longer functioning? I can't open the app without it closing immediately. I'm on stock ROM and first started to experience this last night out of the blue while using cR Droid. I haven't done anything to cause this type of behavior, so I'm not sure if the latest version is just buggy. I've tried uninstalling updates and reinstalling but I still have the same problem.

it just closes? or shows a blank screen? (you checked camera access is enabled in QS).
Go to play store and hit uninstall on the camera (it'll revert the camera back to the default version the phone came with).
Also try the camera in another app (it doesn't use gcam but the camera api). Also try gcam in safe mode..
Ok, so I figured out what the issue was. I had forgotten I had the quick tile "sensors off" enabled for the entire system, which was causing the app to dismiss itself upon opening.
It didn't appear to ever "crash" because it started out OK for half a second, then it would close. I tried 3rd party apps and the camera wouldn't work either.
I have sensors disabled because my phone's screen is constantly turning itself on when I'm in my car due to movement (which is about 8 hrs of my day), which causes it to hardly ever enter deep sleep or doze because it's constantly waking up, which increases battery drain. I don't have lift to wake, only tap to check my screen for notifications.
If anyone knows of a better way to help my display from turning on due to slight movements I'd appreciate it. I tried using "Naptime" app but that didn't seem to disable motion from turning my screen on. It did at first but idk why it stopped working.
Sorry for the post!

Tasker/Automate script to detect when you're connected to your car's particular Bluetooth (assuming it has that), and when so, turn sensors off, and when not connected to your car's Bluetooth, then turn sensors on.
