New Issue about camera!!

i noticed a strange problem after i did the following:
1- Configure Face lock for the device and it's working normally
2- connect the device to PC.
3- after using the device normally for about 5 min restart it while connecting to the pc.
i'm not able to unlock it using the face lock anymore as the Front camera isn't working gives black screen even after restart!!! the back one as well!!!
i made data factory reset (twice) and the camera is back to normal.
has anybody been there or tried this before??
this happened to me 2 times after doing the same above steps.
can somebody help

in which mode do you connect your phone to the PC? If its harddrive, the issue might be that the camera cannot access the phone's memory and will not allow you to take picture.

of course not harddrive!
it's only in 'charge only' mode
also if it was like you said, after restart it should be back to normal but it doesn't
and its not about taking a photo, its about the camera itself doesn't work gives me black screen only.

This is the most similar thread I've found to my problem.
I noticed today that my camera isn't working anymore. When I'm starting any camera app the screen is black for a while(some ui elements are still visible). After ~10 sec the screen is covered in multicolored stripes. (cant link image since I'm a new user :/ )
The last time I remember it working was when using front facing camera in skype.
I have tried a couple of other apps, restarted and factory reset the phone with no results.

Camera not working after long time (black screen).

Hi everyone,
I've just started the camera via code and I used debugging mode so that it never stops until I tell it to do so.
This way I started it and I went out for shopping and forgot to disable it (yeah I know, but the store was about to close in 5 mins). When I went back it was still on so I disabled it. After that I started again but I got no camera at all. Even with other apps like the included Camera-App there was ALWAYS just a black screen. The phone was warm but not hot! I then made a reboot of the phone. After that it worked again.
Question: Was it a hardware failure or a software failure? Why worked it immediately after rebooting? Or to be exact: What was happening here?
Thanks!
Regards

[Q] DHD Display flickering; How to repair?

Hello Forum,
seems that my DHD has an irreparable error.
But i've still a little hope that maybe someone of you guys out there can point me into the right direction to repair the phone again.
What happened:
on December, 20. for no apparent reason the Display started flickering approximately 2 cm from the top.
The upper Part (the first 2 cm from the top of Display) was showing the normal Picture, on the lower Part the Picture was flickering at irregular time intervals, but the touch gestures were still working without any Problems.
Setup at that Time:
- Latest 4ext Touch Recovery
- Latest MIUI.us Rom by bliind
- Custom DPI set to '190' (with ROM Toolbox)
- Max CPU Speed set to 1200 Mhz (with Set CPU)
(Had this setup working fine without any issues for approx. last 2 Months...)
Last change i did before the error occured: Set Custom Boot Animation with Rom Toolbox
The Flickering started not immediatly after setting the new boot Animation but i think 2 days and some reboots later...
Actions that i've already tried to solve the Problem:
1. Shut down the Phone, pull out the Battery, wait some Minutes, reboot the phone.
-> The flickering was gone and the Display looked normal after reboot.
2. After some time I took the Phone out of my pocket and the flickering was there again like before.
Tried to set DPI back to original value '240'
reboot the Phone
-> The Flickering still was there and it seemed to me that the responsiveness of the touch was slightly slower than normal.
3. Reboot into Recovery
Nandroid Backup all Partitions to SD-Card
wipe all partitions except SD-Card
new, totally clean flash of latest MIUI.us Rom by bliind
Reboot the phone
-> The flickering was gone; responsiveness of the screen normal as it was always before.
4. restore all apps; put the phone on the charger over night. everything worked fine again.
on the next Morning this strange flickering was there again; the Touchscreen was very slow responsive in the flickering area
Managed once more to reboot into recovery, but the flickering was now even in the Recovery and on the boot screen.
-> The Touch got more and more unresponsive.
Could no more start a new ROM flash out of Recovery.
5. Tried to access the phone via aahk tool and restored last stock ROM
-> After Reboot the DHD vibrates (like it usually does for startup)
the screen shows a bunch of black and white Stripes that chnge their Color when the Boot Animation should show up,
and later again when the lockscreen should appear.
It makes the boot jingle and i can send Commands via adb.
but Touch commands doesnt work, (tried to put in the Pin blind, but it shows no reaction)
Stupid, but I can't change it: my Warranty and the extra Insurance that i purchased for the DHD ended just 2 weeks before on 6. December.
6. Disassembled the whole phone with Help of you tube disassembling Guide, carefully cleaned all contacts and assembled it again.
-> nothing changed; same behavior like before disassembling.
What can I do? Any ideas except of small rasping and stirring into the soup? :crying:
Can it be only the display? Maybe the Graphic Chip?
Any other ideas?
thank you for reading this all and i appreciate any suggestion that might give my DHD a new spirit of life

I know it's not what you want to hear, but that sounds like a graphics or display hardware problem...

Thanks for your reply!
That was the same what I thougt after disassembling and cleaning with no result.
Cause it seems to me that the Display is still working, but the Signal that's coming in is broken.
I alsready supposed that the Graphic engine is broken.
Just had a little Hope that someone might had the same Problem and got it solved,
before I start practice for mobile phone throwing competition...

i suggest another ROM JB used to cause my DHD flickering (earliear versions)

My DHD was with same problem 1 year a go, and that usually happen when i played games like Angrybirds or Asphalt, or when the device temperature was high.
I was worry at that time, thinking that the device was gone.
Take the same solutions that you had (except disassemble the phone) but they're only temporary.
By that time i decide root the device and install a new rom, (nothing to loose had i think) and Revolution HD was my choice.
After that my DHD didn't flick any more.
I didn't ever know what was the origin of that flickering but for me, that was the big solution.
I'm using Viper Venom 1.2.3 for now, and still with no flickering insues.
So, my advice for you is... give a try to other rom's and kernels, maybe you resolve your insue has i did.
Good luck with that.

Thanks for you Answers guys,
the Problem i have is, that my DHD does show only sripes even if I try to boot into Recovery, I can't see anything and am not able to start a flash process...
cause i have installed 4ext touch recovery i need the screen to wipe and flash a new ROM.
But i will try to flash an CWM - Recovery through ADB and then to start the flash Process blind by tapping the buttons...
let's see what will happen. There's nothing to loose...
For now, cause I was sitting without a mobile phone at all, I've ordered a cheep one from Amazon... - Huawei U8510 (Ideos X3) -
And oh WONDER!!!: I've got a fully functioning phone with CyanogenMod 7.2 and all the stuff i use my phone for is working without any Probs..
And the whole thing has 2 years of warranty at a cost of € 80,-
only the Display for my HTC would cost € 40,-
so I'm thinking of selling the broken phone on ebay and let anyone try to repair it who is able to....
but I will give it a try to flash another ROM.
Already downloaded the JellyTime R30...

Hello unbeteiligter,
seems that my DHD has nearly the same issues, but with some extra problems.
It seems to be broken since today morning. I wiped the phone and restored the backup I made the afternoon before, and then the first vertical stripes occured. I wiped it and flashed the same rom (CodefireX 4.2.1) again. Same issues. Now I tryed to flash a GingerBread Strock Rom. Even the same issues, and even more shocking is that this problem also occurs in the bootloader, recovery, splashscreen and bootanimation.
Stupid situation, today my Warranty ended.
What can I do? Previously I tougth this is a software problem, but now I think it might be a hardware issue.
Thanks in advance!

Seems to be the same like my DHD. But for me it ended up 2 Weeks after end of Warranty!

The T-Mobile Customer Support told me, that they would have accepted the case as Warranty, if my DHD had ended up during the first week after End of Warranty. Don't know where you bought yours, but maybe there's a small chance for you to get Warranty Support through their obligingness.
If I were you I would try this...

If your dealer don't accept your Warranty Call, I can't give you much Hope... Sorry for you...
... would imagine you should look for a new phone...
That's what I did....

Similar problem
I have also got a similar problem. Had my phone for two years and have also just hit the same problem. Flashed a new ROM, everything was working fine, then all of a sudden top half of the screen is displayed correctly, the bottom half is always flickering. This occurs in the bootloader as well. Anyone would think that HTC decided to make sure the phone only works for two years and a few weeks after the warranty expires to make sure it experiences problems.

[Q] Galaxy Note 2 dead.

Hi all,
I have a galaxy note 2, bought in November 2012, I rooted it a few months ago.
Yesterday it was fine, battery was fully charged and it was in my pocket.
It was not doing anything out of the ordinary but when I went to check the time I noticed it was off and I couldn't get it to switch back on at all I tried removing the battery, putting it on charge and still nothing. I tried recovery mode too - nothing.
The only thing that happens when i try switch it on is the little red light from the proximity sensor flashes for a split second.
Has anyone heard of this before?? I've searched and cant seem to find anything like this.
Any help would be greatly appreciated.

try to flash Stock firmware via Odin....

Unfortunately this is the main symptom of Sudden Death Syndrome (SDS). There is no known way to fix it by yourself.
Contact samsung service center ASAP.
Can you answer these questions.
Which firmware was installed on your device?
Have you updated your device to the latest update?
Till you updated it, have you done a factory reset with the old firmware?

Exactly what was happening to me. Had the Notification LED blinking, wanted to check, couldn't manage to turn on the screen. Tried rebooting, but can't even see the boot-logo. Battery pulled - nothing. USB port not working when connecting to a PC.
I had MIUI on it with an increased counter, since here in Switzerland it isn't a big deal when you mod your device.
I hope they will ignore the fact of the increased binary flash counter...

Camera not working, freezes the whole phone and makes it restart each time I open it

I have LGG3 D855 MM stock rom, before I've had fulmics rom and that's when the problem started happening, figured a clean wipe and going back to stock rom would solve the issue but it didn't.
Flashlight won't work, tried other camera apps but it always fails.
Sometimes the camera starts working for a fraction of a second then it seizes to work and freezes the whole phone making it restart.
Figured it might be a hardware problem, but can a hardware problem with the camera freeze the phone? I don't really know, sorry.
Can anyone please help?
Update 1: Tried re-rooting the device and installing fulmics rom, still no luck, tried installing V10 camera app, nothing new.
Update 2: Front camera works sometimes but the image seems stretched, also it crashes after seconds and goes to black screen then freezes the whole phone sometimes making it restart by itself.
Tried the force stop and clearing cache and data trick in both camera and gallery and still no luck.

sounds like a hardware issue like a bad mainboard or connections loose or something, did the phone get wet? have u checked the camera connections with phone apart?

I've actually replaced the rear camera but am still having the same problem only without the phone restarting, maybe it's a problem with some wiring I guess? Any suggestions please?
Also, the phone never got wet.
