[Completed] [Q] Xperia Z2 camera blackout - XDA Assist

Hello!
I am new to this forum, and I am desperate to find some help here.
Problem is that my Sony Xperia Z2 rear camera has stopped working. Front camera is working fine with default app, but when I switch to rear one, it just becomes laggy and only black screen is shown. I tried to run phone diagnostics at settings, but rear camera is still black. Found solution to get into bootloader and do hard reset, clear dalvik and other caches, but it will probably ruin warranty.
Camera seems physicaly alright, running an app makes lens move and silently click.
I can always get phone to warranty center, but it takes 2 weeks to repair it, but I am in love with this phone and it is last resort for me :cyclops:
Any advice is greatly appreciated.

Faulty Phone or Software Bug? Help.

Hello all,
I've had my HD7 since the day they came out and its been brilliant. However, I think it's now faulty, unless somebody can point me in the right direction.
When I load the camera, all the colours are wrong and I get a kind of circular rainbow effect right in the center. The attached pics show the same image. One is with the flash and one without. One last thing, is the night before today, the same thing happened but a simple restart of the camera app resolved the issue.
Should I just take my device back to the store?
Cheers,
James
Have you tried completely resetting the phone from the settings menu?
Settings > About > Reset Your Phone
You may already know this, but be warned. It WILL completely delete everything on your phone
test post.
Hi,
Thanks for your reply.
I didn't think about doing a full reset, but I guess if it's going to be sent away/replaced then I guess could. Before I do so - can I backup all my contacts and messages? (Music and Photos are done automatically by Zune I see) and Apps, will they get restored as well?
Many thanks, James
I bit the bullet and did a reset. Still same results - I guess it's back to the shop. D'oh.
Thanks again, James.
your lens isn't dirty is it? I've seen some bad pics caused by dirty lens covers...
If only Lens is clean as a whistle. Also, when you cover the lens completely, you're left with a purple/red noise as opposed to a black/grey noise.
If you like, I can upload more pics?
Well, I went to the shop today and they were more than happy to send it away for repair or replacement. Now i've just got live with a nokia 2730 or something rubbish for a week.

Sony Xperia U - Camera Problem

Hello friends, after lot of confusion I bought Sony Xperia U yesterday.
Phone is great. I am facing a problem with dedicated camera button. Phone is packed with nice camera, and On screen click works like a charm.
Just the dedicated camera button doesn't respond at all. Someone else is facing the same problem? or is it just me?
P.S When I checked for updates, my phone says all the firmware are up to date. So I guess it's not a software issue.
Please correct me if otherwise
Xperia U
I also have problems with camera button, and also the power button is a bit unstable.. But; i tried another x U in a shop yesterday and i think some covers are bad, cause that one worked the way its supposed to. (sorry for my english, i am scandinavian )
You mean it's not functioning ? you should've tested all the phone's function before you leave the store .. best solution is bring it back to the shop for repair or if they may allow replacement, then it will be better ..
my camera button was a bit stiff and unresponsive at first....but after a bit of usage it gets better..now it works fine...
I found that you have to press and hold the button for it to respond. Its because of the case design, if you remove the backing the button is very responsive.
Design flaw.... YES!

Both cameras and flash don't work! Help please!

I'm running Cyanogen Mod cm-12.1-20160310-NIGHTLY
Yesterday, I dropped my phone in a river and, it being advertised as waterproof, didn't worry me too much (NOTE: this was the FIRST time I've ever fully submerged my phone in water). After around 5 minutes, I fished it out and it worked fine after I wiped it off. Today, when I woke up, neither of my cameras worked and my flashlight didn't work either. When I try to turn on the flashlight my phone completely crashes and when I try to use the camera, the app crashes. PLEASE help me as I cannot get a new phone until my exam results come ( around July) and I love taking pictures of everything I do.
Try hard reset. It might not be water damage

try a 3rd party camera app ?
Same thing happened to me when I dropped my phone. It was in a case, but unfortunately while the phone was "protected" with a "rugged" case and matte screen filter, the camera stopped working, which means that maybe a cable got disconnected inside, this has nothing to do with water exposure. I haven't tried looking inside to see if it's something that can be fixed easily, though.
EDIT: Moto G3 XT1540, stock rom rooted with Squid kernel. My camera was working just fine beforehand.
EDIT 2: Well, the two cameras are working after reseating their cables, however DO NOT use a metal screw driver to pry off the screen, use a credit card, as I ended up breaking the screen while trying to repair my own device.
EDIT 3: I would suggest not disassembling your Moto G if you don't feel comfortable doing so.

Please HELP!!!

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?
