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.
Greetings,

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.

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.

S7 wake up random screen flicker bug

Hi, does anyone have random screen flicker (white flash) in miliseconds when pressing home button and waking up the screen? For me its randomly appearing when I wake up the phone from sleep just before lockscreen fades in.

Yes, I have it on stock kernel, but did not notice it on Superkernel V1.1. Probably it'll be patched in the future.

I hope so, its really annoying...

I only have blue flashes instead of white. Have seen it in GS3 too. Think it's normal. Isn't it?

I dont think its normal, I had S4 and all ok... On which Firmware version are you? Im currently on APB9 thinking of switching to APC8, maybe there isnt that bug since few people reporting the same bug...

It occurs very rarely and was experiencing this from S3 to S6 and now in S7. It should be normal.

Installed the new APEQ firmware, bug still present but rarely...

I too have the exact same issue. Yesterday I took it to service center & this guys just reflased the rom (Factory setting) & said there is no issue with the unit everything is working fine.
Today i saw the flicker again & recorded a short clip to show them but theg refused to accept it & said its normal.
I don't know what to do shud I live with it?

I just got that too. Its normal they say? Thats bs.

I had the same problem several times all of the occured while the lhone was charging

Any idea how to fix this? It is related to a hardware problem?

No ideeas ???

It is not a hardware problem, most probably a software issue. I see it when I unlock my device just after I lock it. Most probably animation can't keep up with the screen etc. I don't care.
Edit: when you have aod on you don't encounter with the same problem.

So its not a flickering screen hardware problem(more often in cold wather) like S5 has (with this problem becoming a green flickering)??

Has anobody been able to find a solution to this problem?

It's not happening on nougat anymore.

I think i have read somewhere that L Speed is causing this. If you have it, try to uninstall and see if there is any change.

S6 camera problem

Hello guys
I opened the camera app and there are strange vertical lines going right to left like on the old tvs and even when i take a photo they are still visible.What can be the cause. Can this be caused by water or something? The story is i was heading home when a warer drop dropped on my screen like on the middle of the screen i have a screen protector and i cleaned the screen so i dont think that caused it .

Have you tried the usual like restarting the device? If so and you still have this issue try clearing the cache for the camera app via app manager in settings. If that still doesn't work try a factory reset.

Start the phone in safe mode and open Samsung test menu with *#0*# (if u can't open it u are probably running a custom ROM with no test menu support in it)
Try the camera test in there. If the problem is still there u have a faulty camera.

So my problem is a bit different but it is still a camera problem. So my camera started acting funny a while ago and mos of the time it wouldn't open at all and blocking the front cam from working as well. So i ordered a new camera module online thinking that was the culprit, as the old one made a rattling noise when opening the camera. At last it arrived today so i swapped the cameras only to find the same problem persisting. I have also tried different firmwares and custom roms but still nothing. Does anyone know a cause or a fix for this problem?

Touchscreen issues

Ok read the other posts but having touchscreen issues with the phone running Resurrection remix latest ROM. Only happened over last days and I cannot remember dropping it.
Its the middle part of the screen that sometimes do not respond.

Was working and then suddenly just stopped responding to the middle part of the screen. Resorted back to back up and same issue
Is this a hardware issue and is there any fix?

Anyone helped here or is the phone Fubarred?
As getting annoying. Was going to try a factory reset but not sure if it can be fixed by this. Is there any fix like replacing screen or is that cash down the drain?
cheers

thing is I dont want to waste spending euros if this wont fix it. The top and bottom of the screen work ok its just the middle and screen not cracked or anything but if I spend money on it and it does not fix it just a waste of Euros then. Before I do just want to check could it be any other issue?

Reading up I can see it maybe the digitizer also. So If the screen gets replaced does the digitizer get replaced with it, Tried to find out if they are connected?

They must be replaced in combo.Even if there's a way to separate them,it might not be the best idea.

I registered just to respond to you and let you know that replacing the screen did not work for me.
I bough this phone online a few months back but gave up on it because it was literally unusable due to ghost touch inputs. I have since installed LineageOS and completely replaced the old screen and STILL get ghost inputs along the whole right edge of the phone.
Some people say it's due to an issue with the grounding of the screen. I've tried many solutions and the touches still seem random.

Peculiar behavior observed on my OPO - Screen freezes regularly

Hello Devs,
Need help help :crying:
I have been using RR(7.1) for last 4 months. from 05/27 I have been updating to latest in between installed substratum and applied tweaked themes on it... all of a sudden I started observing below problems
1. Screen freezes on my OPO(can't able to unlock the screen forcing me to restart it).
2. Some letters from keyboard are not functioning properly, I thought some touch screen issues..installed some touch screen test apps it shows everything fine.
So I roll back to 05/27 but no use same problems, then clean flash - no use, reset the phone i.e, factory reset wiped everything.. and flashed latest Lineage 14.1 - but no use still I see same problems.
Switched to Tuga power - No use same problems
Finally decided to rollback to 6.0(Marshmallow) and flashed (sultan's CM13 latest) - Still I am facing the above mentioned problems. :crying:
NOTE : in between TWRP touch screen also behaving differently ??

If touchscreen has issues in TWRP also,then it's a hardware issue.

Any procedure / apps to test hardware ?? If so let me know please

There're several touch testing apps on Play Store,but TWRP having issues also points hardware issues.

Touch screen issue
I have installed few screen test & dead pixel fix apps, I found that some vertical part(left side) is non responsive please refer the attachment. I assume that that is the reason for my screen freeze / flickering a regular intervals. so any suggestions to fix this issue?
Even when I keep on touching the screen that particular area is unresponsive as shown in the attached picture, please do suggest if it can be fixed through any software? or do I need to consult hardware technician ? if so how much would be the cost?
Thanks in advance.

Any suggestions please ??

Actually there is no problem with display, but ' touch ' is not working properly on particular area so.. do I need to change the LCD Digitizer for that?

You can't separate digitizer and LCD,they're to be replace in combo.

A good quality LCD digitizer costs 2500, so if I sell the device how much will I get ? any idea on average price of OPO 64GB, 2.6 Years old with minor dents on corners ?
