Camera not working after long time (black screen). - HTC One X

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
Fresh

Screen turns on/off randomly

Hi, I'm new to this forum.
Some days ago my DZ started to turn on the screen randomly when it was locked. The phone is rooted, so i tried to wipe all data and install an updated version of my rom (virtuous), but it did not help. And now the screen also turns on/off (flashes for a couple of seconds) when I use it.
Does anyone has had this kind of trouble before? I hope it's not some hardware that are broken :/
Thanks for helping!
How's your phone now? My G2 was doing what sounds like yours was doing too, and then just died completely (the screen that is everything else works).
I bought a new LCD replacement hoping it would fix the issue. Followed a Youtube bit on replacing it, and successfully reconnected everything, but its not working. I'm going to be taking it apart again tomorrow to see if I possibly missed a connection but I don't think the screen replacement is going to work.
Could be a software issue perhaps. What are your thoughts?

[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] Phone stuck in screensaver mode

Hi!
I brought my Xperia Play phone USED two years ago and I've never had any problems with it.
However, recently, the phone has started to freeze itself in "screensaver" mode (Where the screen goes black after 15 seconds and locks the phone), but the screen won't light up no matter which button I press. I've had to restart the phone every time this happens.
It's been behaving strange at start up as well, as it sometimes take 20 minutes just for it to turn on, while on other occasions, it won't turn on at all!
Is this problem caused by the battery, or is it the hardware?
Is it with stock firmware?

Yes.
I've never modded it or installed custom firmware/apps.
Have you tried factory resetting it?
Vortelf said:

Yes, but it didn't fix it. The problem still occurs.
tldr: Black screen, no display, everything works "under" (I can answer the phone etc). Not a flex cable problem because occurs randomly, regardless of the slider being open or closed. The problem also occurs during boot up, so rather not a software problem.
I think I have something similiar. Everything was fine until a few days ago the screen didn't want to unlock..or at least I thought it was that.
Basically the phone sometimes works OK but sometimes if I turn off (lock) the screen, it won't go back. To be precise, the phone works and if someone calls me I can pick it up moving the finger where the slider should be, it's just the display doesn't turn on. Same goes for booting, bootloader logo etc, so IMO it's not a software problem.
Strange thing is that it just randomly pops back, sometimes when I move the gamepad slider, sometimes when I put in a jack cable or if I hard reset the phone (remove battery). I've had problems with the flex cable in the past and this time I know that it's not it (no difference if I open/close the slider).
My guess would be some power supply or LCD driver IC issues, because the screen stops working almost everytime if I put the phone into the dock. Moreover, if the screen doesn't work, the orange charging LED is not working (green and blue are OK). The moment the screen starts working, the orange charging LED starts working too.
it's very strange but I'm used to electronics doing strange stuff. Just wondering if I should give a try disassembling the phone and trying to fix it or just buy a new one or something?
I might add that I have bought a new battery ~3 months ago, but it's been working fine to this point. I have tried if the same problem occurs with the old/original battery and it's the same.
well, any ideas?
edit: This video shows something very similiar (except the backlight): https://www.youtube.com/watch?v=m4p0-kv1cxA
Same problem. And I guess this guy has it too.

SM-N7505 Wi-Fi not turning on

Hi everyone,
I'm having serious problems with my Wi-Fi on my Samsung Galaxy Note 3 Neo (SM-N7505). Whenever I click the button to activate the Wi-Fi, the icon goes from grey to a dull green (darker than the bright green which signals that a function is turned on), as it does when it's trying to turn itself on. Problem is, instead of turning on, it just stays in that state for a few minutes before reverting to grey. This has gone on for a while, and I've already tried several possible solutions which I found after online searches. I don't think it's a hardware issue (see point 1 for the reason), and I really hope it isn't, because my warranty has been voided due to rooting, so I can't have my phone replaced or repaired unless I pay for it (which I can't at the moment). So, I'm basically ignoring the possibility of hardware failure and trying every possible software solution, hoping one of them will work, otherwise I'm just stuck with no Wi-Fi. These are the fixes I've tried:
1) Take out the battery while the phone is on, wait a few seconds, then put it back in and boot the phone up. This used to work when the problem first presented itself a few months ago (which is why I don't think it's a hardware issue), and I've been since using this method to fix it whenever it happened again. But a few days ago, this method stopped working for whatever reason, so I was back to square one.
2) I tried renaming the data/misc/wifi/wpa_supplicant.conf file, which seems to have worked for some people, but not for me.
3) I tried updating the version from Kitkat to the recent Lollipop, hoping that would fix it, but nope.
4) I tried deleting practically every single app one by one, hoping that one of them was interfering with the Wi-Fi somehow, but nope.
5) As a last resort, I tried a factory reset, but not even that worked.
This is basically the long and short of what I've tried to fix this... I might've skipped a few of the simpler fixes I tried (for example, I just remember I tried disabling "Smart Network Switch", which seemed to do it for some people), but the big stuff is all there.
I'd really like to get my Wi-Fi back, so if anyone could help me fix this thing I'd be really grateful!
Thanks in advance to anyone who will bother to reply.
same problem dude
Same problem...wifi and bluetooth not working...pls help us
Same Problem for me, Initally it works fine even after updating Official Lollipop update (OTA), but after few months now wifi & bluetooth are not working for me. And finally faced battery drain issue for past few days. Battery goes down upto 20% per hour even in idle condition. Then i rooted & installed Note Rom & even after i face the same problem. Is there any way to fix?

Pixel XL stuck in bootloop.

There are similar threads but I think my problem is different from the others.
In the morning everything was fine for about an hour but once I left the house my phone froze out of nowhere. In the beginning It was still able to reboot into Android but always crashed shortly after and right now it's looping. I can still get into fastboot but recovery mode doesn't work, I just get back into the bootloop, probably because the phone crashes before it enters recovery mode (first google logo shows, then it crashes).
Sometimes when it crashes it produces really weird artifacts, which can cover most of the screen or are only a few pixels large, in different colors.
I found this guide which might help but I can't get into Recovery Mode anyway.
I read about the contacts getting lose, still gotta figure out if certain scenarios will allow it to boot.
Software is stock Android, on the latest update the Pixel XL received.
Update1: So after about 7 hours it finally booted to Android again, after taking of the case (cheap plastic one). And it does so consistently for some reason but sadly still crashes after a few minutes. Maybe it's heat related, the phone always got warm more easily with the case on.
I also just noticed that the phone restarts on it's own after crashing (and for some reason activates the night light) which could mean that it's trying to protect itself from damage.
Update2: Seems to be temperature related. I put it on a cold ice cube tray and since then it didn't turn itself off.
Considering the fact it restarts on it's own there could be some error logs, how could I retrieve those?
Update3: Higher tendency to boot when battery is low.

Maybe replace battery?
Hi there! I am not sure if your problem was fixed yet. But my Pixel XL died yesterday and did the same exact thing. It went into an infinire boot-loop, and after trying many times to power off and reboot, some weird artifacts appeared.
I think I messed up the phone, because at first the phone booted and then restarted, but now it just restarts and never ends....
EDIT: After some hours of rebooting, and more artifacts, the Pixel finally booted on android. Battery was at 4% so I guess that helped. It keeps rebooting from time to time, but at least I can copy my photos now haha.
