Camera Problem

I'm having a problem where the camera works for a couple of hours then just turns completely black and doesn't start working again until i reboot the phone.
When i say works for a couple of hours i don't mean a couple of hours of continuous use but a couple of hours general use of the phone.
I first notice it when I'm unlocking my phone as i have Face Unlock enabled,
The front camera won't start so i have to unlock using the backup unlock method (pattern in my case).
As soon as that happens the camera stops working all together, even in the camera app, like i said, until i restart the phone.
Any ideas ?

I had the same issue last night, I went to take a picture but the camera was just a black screen until I reboot.

I can confirm this as well. Only fix i can tell is a reboot.

Exactly the same problem here... Android 4.4 Bug I guess

Same issue for me, and i also have face unlock enabled. Very annoying.

I didn't wanna say anything as to not jinx it but i tried something that seems to have helped my situation.
I Force Stopped the Camera app in Settings --- Apps and then cleared the app data.
That didn't magically fix it but after doing that AND rebooting my phone i haven't had a problem with the camera.
It hasn't even been a full day yet but it's been working for about 18 hours which is great compared to yesterday's having to reboot every couple of hours.

Same Problem here. Also have face unlock active...
Thanks guys for reporting it here!!! I was really close on exchanging my otherwise perfect phone! Now I really think it's software and not hardware related.

Does anyone here get the bottom of their picture blurred out when they use flash? It always looks like if my finger is covering the lens which is not.

I get my Nexus today/tomorrow. I'll do some diagnostics and see if I can find out what's causing the black screen.

Happened once, black screen, reboot. I wasn't able to reproduce it yet.

So much for my "solution"
Just happened again.
I'm tempted to try a factory reset or flashing a factory image.
If anyone's actually tried this I'd appreciate a heads up.

Same for me

I've had this problem on the Slim rom and flashed the factory image yesterday.
Last night, the camera was working well until I switched to a panorama, then it was black.
After a reboot I wasn't able to reproduce it.

There goes my plan to flash the factory image
I hope that it stays fixed for you but unless someone who has had this problem is able to confirm that they haven't had this happen to them for at least a couple of days I'm gonna stick with "This is a serious problem" (for me at least)

This is very unfortunate! Luckily I haven't come across this issue yet but I haven't used the camera much. BTW does anyone know how to change the focus to continuous? Can't find the option.

Apparently this is related to Face Unlock.
https://code.google.com/p/android/issues/detail?id=61873
If anyone can confirm this ?
Who has had this problem and not used Face Unlock ?

No idea why this got posted twice.

The only way to "fix" it at the moment, is to turn off face unlock.

My back camera started crashing when i tried to take a picture in complete darkness and ever since i only get a black screen. I have tried to run the phone on safe mode and rebooted many times and it still gives me a black screen. Today i flashed my phone with the factory image and it still broken. I am suspecting this is more than just a software bug. Can anyone confirm this?

Adding myself to the problem with Camera randomly not working, and fix with rebooting.

Proximity sensor doesn't work during phone calls

My screen goes black when I am in a phone call and it does not turn on unless I hold the power button or something like that. I have already went to the proximity settings to test that it is working.
Any ideas?

Firmware version? Seems to be a bug in last firmwares. Also had this issue some time. Now it seems to be gone.

.In the process of backing up my phone atm to try a factory reset. I'm on latest T-mobile version though.
How did you fix yours?

Bump. Anyone? Is there a fix or is my sensor faulty? Because if it is I can still send it back in for a replacement. Sometimes it will work fine, and sometimes it won't.

I've got similar problem. When sensor is activated, it's keeping activated even if nothing is in front of sensor, so I have to wait for other side to end a call.. any suggestions?
EDIT: problem solved-> I just cleaned the glass on proximity sensor, maybe some dust was there

I also have a problem with phone's proximity sensor. With me, it shows some signs of work right after i boot up the phone. In service menu (*#*#7378423#*#*) -> Proximity switch starts with On value and then goes Off, On, Off, On.. a cycle of at least one minute. The interesting thing is when i cover the sensor it stays On, which means it detects its working. I suppose the sensor is faulty, as I tried several suggested methods to resolve this issue: pressing firmly on top of the sensor, factory resets, reinstalling the software with Sony's PC software kit, some applications from Google market, etc. None of them helped.
As I bought my phone 2nd hand, I see the upper speaker is pressed on its left side a little bit, as if the phone was dropped exactly on this spot at the speaker (which I find is almost impossible, as the front panel is perfect without scratches or anything) or somehow it was pushed with some sharp object. I explained this as it might have a link with the proximity sensor issue, or it may not be connected to it, not sure.

Google Pixel 2, Black Screen issue

I have purchased Pixel 2 on 1st November from 3rd party online shopping, it was working fine until 5th December suddenly it's display went off , and never turned on, but phone is responding to touch, and also phone is ringing when receiving calls but not able to see anything on screen.
I have tried soft reset (holding power button for 30 sec), Flashing the OS 8.0 & 8.1 manually (successfully flashed) but still Display is not up.
If anyone has similar kind of issue & was able to resolve it. kindly let me know

Does it ever display at all, e.g. in bootloader, recovery, or splash screen when booting? If it does then the hardware is OK, and it's a firmware/software issue. If not then it may well be hardware. If you've already reflashed it with 2 different images and neither helped my suspicion is hardware anyway, so I think this is probably a warranty job.

The ribbon for the screen probably somehow came loose, or the screen is just defective. If there is nothing on the screen anywhere, even in bootloader, it's definitely gonna need to be replaced.

Pixel 3 screen flash

Didn't see this posted here yet, but forgive me if I missed it.
Trying to find out if anyone has seen or heard of any acknowledgement from Google regarding this. My new Pixel 3 (Verizon; non XL) since day 1 has had an annoying issue with the screen flashing when ambient screen engages. I have my settings with alwayson set to off, and new notifications set to on. If the screen is asleep and I get a text or any notification, the ambient screen wakes and will initially make the entire screen flash white very quickly.
I do not get a flash of the screen in any other scenario when the phones on, it only seems to be when the screens totally asleep and the ambient screen wakes. I can unlock the phone or hit the power button to fully wake the phone to my home screen with no flashing. Its not every single time, but its very often. I do notice sometimes when it doesn't flash the whole screen, the time or text on the ambient display will be at full brightness when it first wakes for a split second and then will go to the dim text Im used to seeing.
Replaced the phone through Verizon. Got another brand new one with the same exact problem. This one even flashes on reboot occasionally just before the white "Google" screen pops up. Google had me send them a bug report this time and are supposed to be having their dev team look at it.
WHY.

Mine did it once

I've also now noticed mine will flash in Instagram when I "like" something lol. Just the picture flashes within the app itself in that case, not the whole screen. Such a weird thing, that may have something to do with the app on the new pixel? I don't even know anymore.

I just saw the white flash. It was only for a few ms but it looked like a full brightness white flash on the whole screen. I had just set my phone down and I think the AOD was coming on.
Weird.

Yeah I have a feeling this is happening on way more devices than we're reading about. I hope it's addressed. Sometimes my notification audio cuts out real quick too. Hoping it's just all memory related.

I have this weird kind of screen flickering on my device as soon as I use the fingerprint area to turn the phone on. It is very faint and fast but its like static lines for half a second when the screen comes on??

Strange, I haven't had any issues like that using the fingerprint reader or just hitting the power button. Mine are all directly related to ambient screen waking.

My Pixel 3 is doing the same thing when I unlock it. Flashes like taking a selfie... I have even looked for the selfie to no avail.
It does not do this regularly, very random.

Same here. Sometimes when I tap the screen to wake it up, it flashes. Just did it a minute ago before I wrote this.

I just charged the Pixel face down; during the charge I picked it up to check the progress and I got the screen flash ~2X out of 10.

Report it to Google. I feel like it's something they're aware of (I hope) but support certainly isn't saying so if they are.

I saw a post on Android Police about bug trackers and read in some of the comments that people were having problem with screen flashing. Some of them said it was related to the always on display. Mine was flashing like white static lines. But it was only for half a second when you turn on the screen and it didnt happen every time, it was random. I turned off the AOD and it never happened again. Kinda sucks cause I like AOD. But that tells me it is a software problems and not hardware.

I turned off AOD too, for 1 day; the next day I turned AOD back on. I have not had a screen flash since (a few days now).

Try rebooting. I bet it's still happening you just may not be noticing. I've had my AOD off for a while and as soon as I turn the new notifications option it comes back. Not every time but still often.

I'm having the same issue, doesn't happen all the time but I can reproduce it usually by unlocking the device, locking it then when ambient display comes on, unlock it and the screen flashes/flickers. I've only managed to do it with ambient screen set to always on.
I've RMA'd this morning so I'll report back when the new phone comes.

I hope you RMA's for other reasons too because it is likely that you will get a phone with the same flickering problem. I think it is a software issue esp since it goes away after we turn off AOD.

I just find it strange that people are having the flicker in different scenarios, like mine is only when ambient is set to always on but other people are having the issue when it's set to double tap etc. Anyway I guess I'll see when the new phone comes.

Yeah let us know please once you get the new phone. It seems like it is hit or miss with people so you might get lucky and avoid it.

Quick update. My new phone arrived this morning and I've managed to get the screen to flash once so far where as my old one would do it 8 times out of 10. I feel like this is a poor display hardware problem rather than software.

I believe or rather am hoping that because it only happens when you turn on AOD that it is a software issue and not a hardware one. The only way something will be done is enough people complain on a bug tracker.

Question Screen Flicker During Unlock

Every time I unlock my screen, whether it's with the fingerprint or pattern, the screen will flicker for half a second. Super annoying because it's a bright white flash.
It's not face unlock assistive lighting, as I've ensured that is turned off.
I've also tried every display setting possible, toggling things like vision comfort, comfort tone, refresh rates, display calibrations, changing wallpaper, and so on.
Really hoping this isn't a hardware issue because I'm also noticing my touches don't register all the time, unless I'm pressing the screen slightly harder. Not sure if it's my screen protector but I am left a bit concerned.
Any ideas? I've Googled this a bit and I've noticed others have the same issue but on OnePlus 6 devices for the most part, not the 9 series. If anyone has run into this before and knows a fix, I'd love to hear it, thanks!

That's how the fingerprint works. It increases the screen brightness to the max usually. It's the flaw of using that kind of fingerprint rather than sonic like Samsung. Believe it takes a picture of your fingerprint and compares vs ultrasonic gets a 3D image, the difference is in speed too, optical is faster, but ultrasonic technically more secure and does not rely on lightning conditions. I personally prefer the hardware on the back kind over both.

I don't remember it being this prominent on my previous OnePlus devices, though. My 8 Pro did not flicker as aggressively as this one does. It's enough for me to clearly notice it, even in brighter areas; this is why I've been left with a bit more concern than usual.
Not to mention this occurs even if I use my pattern to unlock.

Not sure. Mine does the same but doesn't bother me in the least bit. If it happened at other times other than unlock would be different story.

Any chance you could try and make a video of it happening on your device? I just want to see if it's the same thing as mine. That way, I'll have a better idea of this being a defect or normal behaviour.
I know, it's kind a big ask so no rush! If you ever have time. I can do the same if anyone needs to see what I am talking about exactly.
Update:
I've noticed the issue occurs only if the lock screen is showing. If ambient display is on and the fingerprint icon shows at the bottom then the device will unlock without flickering. The fact that it's happening only when the screen is on at the lock screen, is what's making me feel like maybe it's not a hardware problem. Very odd issue...

Another update,
After doing more Googling I came to the conclusion that it's a hardware issue over software. I tried to factory reset and the issue was still present.
I couldn't update the software on the phone though. It kept telling me that there was an installation problem. I'm guessing that's because I had previously used a rooted EU boot img and a factory reset through the phone settings isn't enough to get rid of that. I'm hoping the repair center won't fault me for sending the device back with an unlocked bootloader. Doesn't seem like OnePlus would do that anyway, given how open they are with the modding community.
Once I receive the replacement of test to see if the issue was still there and will update this thread.

One time I sent them bricked device and they still accepted the return. Returning unlocked bootloader phone shouldn't be a problem.

What made you think it was hardware since I see other people have the same thing. Hell I had it too. I don't seem to have that problem after updating to latest firmware. Seems to be software to me.
Hope it gets fixed. I saw a thread for it on OnePlus community forum, so hopefully OnePlus knows.

When I sent the phone away for trade in there was no mention of rooting or bootloader unlock. Just wipe it.of your info and data.

Thinking it's hardware because my 8 Pro doesn't literally cause a white flash of the entire screen, it would just up the brightness which is normal.
And I was also noticing my touches only registered on more firm presses. Made me think it could have been a bad display panel.
Didn't want to take any chances especially while inside the 15 day return/replacement window.

Yeah good plan.

It absolutely does NOT do that on mine. Only the fingerprint area gets bright, not the entire screen.

+1 on the 9Pro

According to the OnePlus support section of the site, the progress shows as "Inspected". I assume the next step is shipping out a replacement. Hopefully it's soon, will post an update on the new unit.
Thanks for letting me know you guys aren't experiencing the issue, makes me feel good about my decision of sending it back. Almost didn't do it because I didn't want to come back to this Pixel 5 after being spoiled by that 9's screen size lol.

Got the replacement today, after some testing it seems like this unit has no issues! There is a clear difference between this one and my original. There was a blinding white flash even when using my pattern to unlock. Same thing when double tapping the lock screen to put the device to sleep.
This has no white flashes so definitely seems like a hardware issue. Finally, I can start enjoying this thing!

How bro it can be a hardware issue.. it's only happens on low brightness when you unlock the phone right?I am also facing the same issue but it is not there where I unboxed the phone and used it for 1day after receiving update to os 11.2.7.7only this problem starts to me..so how can it be a hardware issue

No it happened on any brightness. It was just more noticeable in low brightness and reading through the same issue on OP forums, others were confirming it is hardware related as a complete factory reset isn't able to resolve the issue. If it was software related, a complete restore would have/should have fixed it. Your issue might be different from what I was experiencing.
