Restore backup? Flash rom? Maybe change settings in build.prop via adb?

A friend of mine gave me a Nexus 4 with a camera problem. He said that, after ota upgrade to the last version of kitkat, camera stopped to work ("camera not connected" error). Both front and back camera don't work, and led flash too. I've tried every version of android stock, cyanogenmod 10 and 11, and franco kernel too. I've open the phone and unmounted every piece: nothing looks wrong. Maybe logical board? Or a defective back camera? But led flash and front camera don't work too. Maybe a software problem? Thank you
Try reverting back to 4.2.2; see if that fixes it. If not you might have to open it to make sure the wires for the camera is connected.

Try to flash the Google stock ROM with a toolkit then it should work
Gesendet von meinem Nexus 4 mit Tapatalk
But, as I already wrote, i've tried to flash every N4 android version (with unified toolkit, of course), and I've unmounted every piece and everything looks ok. I don't think the back camera is broken, as front camera and led flash don't work too.
Do u think that if back camera doesn't work, the front camera and flash led are off? I tried now without back camera, now without front, and i've the same error.
can you share your topical setup rom+kernel...?

try also to delete your app data off the camera (gallery) in app settings or try another camera app in the playstore and check it again. if nothing helps i think something inside your device is broken
Hi,
Sometimes while taking a pic the stock camera would hang without even saving the pic to album.This generally happens when i open the camera from lockscreen. Another common error is "camera not available".
On encountering this , most ppl restart the phone. However, i have seen on all occasions, opening the multitasking pane and swiping the camera app away will fix this (atleast temporarily)
Hope this helps and u dont miss ur shots [emoji4]

I had this issue while on holidays... even clearing cache for Camera app did not fix it, then I restarted and discovered that fixed it.
It never froze to me and I use black Z1, C6903 and I have firends who have white Z1 and Z1 compact and their cameras freeze most of the times, but I use it or open it from anywhere and nothing.

I've noticed one thing - when I launch camera from lock screen and it freezes when I half-press camera button to focus, all you have to do is touch the icon with cameras (the one that allows you to switch to automatic/panorama/etc) and select Auto again. Camera works then with no issues.

@jontr : will try it out !!!
A minor update : the problem doesn't arise if i am in manual mode...i just switched from superior auto to manual mode after launching from lock screen....manual mode takes better pics in my opinion

LB or UB?
i really wanna try using ur configuration
thanks in advance
last Nut's stock 4.4.4
LB
deodex
superuser mod (by xperia xposed)
..and the fix in the link
I installed 120fps e 4k mod too
I had the problem of the camera hang before to apply the fix
well unfortunately this fix did not work.
i have a xperia z1 c6906 LB.
i tested with ihackers ROM v5.1 the first day i was able to take like 300 pictures without any failure, next day after taking the 12th picture i get camera hang somehow i change between auto and manual and 'fix' for a moment so i decide reboot the cellphone, second day i take about 100 pictures only hang 2 times in auto. today i keep testing and when i taking the second pictures got camera hang u.u i tried to do the same trick changing from auto to manual but it only got worst i lost preview (black screen) from camera. :c.. i make a quick reboot but did not fix the camera preview so i did a full reboot and its working again...
i think i gonna get back to android 4.3 :/
it is really disappointed because both versions android 4.4.4 and 4.3 have bugs
maye its time to change phone and brand
remember, the reboot is required after you have installed the fix
The fix works fine for me. Thanks.
Guys I'll be now testing for a few days since I have this problem too.. I'm on UB, I have chocolatetrain mod installed (pretty nice but this issue hasn't been solved there too..), trinity kernel (dunno if that mathers hahah). I'll tell you more
Edit - ok totally not working here.. Camera still has its annoying problem
Thanx for ur excellent suggestions bros..but my phone is on stock rom and unrooted.....guess thrs nothing i can do abt it for completely getting rid of it

Hello everyone I have the HTC One M8 running CM13 and I have this problem where VR apps start rapidly clicking with this white dot in the middle of the screen as soon as they're started up. The phone then becomes unresponsive as it is registering clicks from it, making the phone freeze up. The only way I can get out of this is by locking the phone and rebooting the phone from the lock screen. I thought it was the magnetometer in the phone doing this so I installed an app to read it and searched up the normal ratings for what the sensor should be at and everything looks fine. I have tried reinstalling Android with a different version and still the issue persists. After a while the phone starts heating up from this and on some of the VR apps I have tried that use the same cardboard system the phone will rapidly vibrate as well. I have spent hours trying to figure out what may be causing this and still, no luck. The phone is not in a case, no magnets are any where near it. NFC is turned off, all apps are updated. If anyone knows a solution to this issue that would be great, thanks!
*Bump* I still have this issue, can someone please help me with this?
It now seems to be happening in Pokemon Go... *Sighs*

I have the exact same issue, the only time when the white dot wasn't showing was when my gyroscope was malfunctioning or just simply "off". I have no clue how to switch it off though.

had the exact same issue. same in pokemon go which ist a vr app. on several cm13 roms on my old m8.
only way i could fix it was to install a GPE rom. might be a cm13 bug for the m8 which never got fixed. so i guess anything not cm (aosp, gpe, stock) will work.
i dont own the m8 anymore but my old one and the one of a friend had ur issue on cm13. on gpe rom everything worked.

This problem was fixed a long time ago. The problem was the uncalibrated gyroscope, which they took out a few days after this thread was made. Just update your phone and it should work
Same exact issue
I have an Lgg3, same process I removed the magnet thinking that was the issue, I updated all apps, removed app and re-downloaded them, have an unlocked phone running total wireless so I used a Verizon sim and updated the phone to the newest version, recalibrated the phone, nothing I mean nothing I can find will work for this issue that I can find. Only does it with 360 apps not on 180.

I just noticed that there is a small white dot flickering (i guess it is a burn-in) on my S7E Rooted. Not sure what is the cause of this, as I always set my brightness to low and screentime out to the lowest.
Anyways, since I cant do anything about it, will it spread (or if it really does) and how can I prevent/stop it?
Thanks in advance.
Update: I restore and flash other ROM but the white dot is still there. Even stock firmware doesn't resolve the issue. .
That's not burn in but it's probably dead/bright pixel.
Does this show up in all screen(at boot,recovery,safe mode, etc) or not show up in screenshot? If not it's might be just your app acting up and not hardware issue.

Hmm... I tried the color test and it is present in all colors except for black. It is not present in screenshot as well. I cant see it in restart and shut down as background color is black. In twrp, the white little dot is visible (when im on Install, wipe etc.).
is there a chance to get rid of this? restore stock maybe?
There is almost no chance to get rid of dead pixel. You can try some dead pixel app to "refresh". This apps fastly switching colors and there is really small chance that it helps.

This is what I was afraid of when I bought this phone for my wife.
Her front camera is no longer popping up when it should.
She has tried restarting the device to no avail.
Is anybody aware of any bug or software issue that might be causing it to not pop up, or do you think it's simply a hardware failure?
Pop up camera just stop working or cell was dropped or something else that could affect pop up camera? If not, my suggestion it's claim warranty. I had this cell since 6 weeks ago and no issues with pop up camera but notice I'm not use pop up camera too much/often.
Start front camera in app and try little to press down camera....maybe this help...

did you updated to android 10? im having the same issue now that im trying the miui 11 beta
---------- Post added at 07:15 PM ---------- Previous post was at 06:56 PM ----------
Ok, so for appearently flashing the 75hz screen refresh rate mod or the the 66hz (as is the only one working with miui 11 android 10 rom) breaks the pop up camera dont ask me why but i reflashed the rom and then flashed one by one the mods i use and this is the one.
So maybe you have this mod installed and is the one messing with the camera.
Cheers
