Camera Flash causing phone to lock up

Hi I was just wondering if anyone has had problems with using the camera on the phone with the flash enabled. I had this problem with ed2 in the past. Today I decided to use the camera for the first time in awhile with the flash and as soon as I took the picture the phone just went to a black screen resulting in me having to pull the battery. I'm running ee4 debloated with the peanut butter jelly kernel. The phone takes pictures without the flash perfectly fine. However, once I enable the flash and take the picture, the phone focuses, the flash turns on, and as soon as the phone takes the picture the screen turns black and the phone locks up. Hopefully someone comes up with a reply. Maybe it's hardware related? I don't remember if stock ee4 had this issue or not. The only roms I've ran so far have been the debloated roms by imnuts.

Happening to me too.

I fixed the issue. Im not sure why recovery was causing the issue but it was. Anyway what you're going to have to do is a factory restore on your current rom. I know that sucks but that's the only fix I could find.
Beamed from my SCH-I510

happens to me too =(. Happened to me the first day i got my charge and Hoping that rooting and changing roms will fix it, but it didn't. I'm not sure how often this will happen because im scared to try it. Last time I took a pic with flash, the screen blacked out so i had to do a battery pull...Rebooted and BAM...i get the "process.com.google.process.gapp" error message. (Happened to me running GummyCharged, now running Altered Beast) So as soon as that happened, I knew that I had to factory reset the ROM. I really dont want to factory reset again because I dont want to go through the process of everything again. Lol.. So if anyone has any advice, fixes...please, share! =).
I was also reading on other forums that maybe the SD card write speed has something to do with it? something with the SD's class. (Class 2...class 4.. etc??)
Thanks!

[Q] Camera app crashing HTC Sensation (Reboot)

Randomly, when I use the Camera app and take a picture with the phone, the flash goes on, and then the phone reboots.
Does anyone know why this is happening? Sometimes I can take pictures and video with no problem, and other times it crashes without fail. It's like when the flash goes off, something in the phone gets overloaded and it dies.
Anyone have any idea whats going on?

It happpened me on my first day with the Sensation. At that time the battery was at low levels (<20%). I tried the camera in the morning after an overnite recharge (so at healthy battery level) and there was no crash. In fact last morning I took about 20 pics without any issues! So it might be some kind of protective mechanism at low levels. There are similar threads on other mobiles as well - Saw one for Google Nexus S!
By the way, the camera is really good. The pics turned out quite well.

Me and my wife are also having this same problem. Not sure what is causing it.

I bought the phone yesterday, and it seems that it is resseting itself every 1,5 to 2 minutes and that without even doing anything with it. I have sent (almost) all the reports to HTC, but not sure what would the issue be. I haven't even tried to use camera...

Weirdly my issues have stopped for now. I thought to myself, while troubleshooting this, is "What other app uses the camera?"
I think what the problem was is that I had a program called Visidon AppLock which uses the front facing camera to visually recognize your face (acts like a security measure basically) and an app called Mobile Hidden Camera, you can probably guess what that's used for
After disabling both these programs, and giving the phone a reboot, it seems to have fixed the problem.

[Q] Camera flash + dark room + semi-charged battery = phone crash?

Came across this trying to take a late night picture in a bar, embarassing
Logged this with HTC support, they claim they cannot recreate so must be a faulty handset, seems like a software fault to me. Has anyone experienced this? Really don't want to return my handset....
Requires these conditions:
- dark environment, so that flash powers up to maximum
- 2G/gprs data connection (doesn't happen if on HSPDA, or wifi)
- battery not fully charged but charged enough so that camera flash option is available
Focus as best you can on an object, take a picture, phone will immediately shut down. Can recreate this every time in same conditions.
Weird.....

Had this happen to me once. Restarted , and ok ever since.

Had this a few times. I think its an software problem.

happened to me as well on the first day. battery was at 20% level at that time. recharged it overnight and tried again in the morning. everything was ok.
There are threads on other droids (Google Nexus S) for the same issue. So it cud be an Android bug.

Maybe the camera flash is causing a drop of voltage in the battery? O_O

I've had this serveral times.
Sometimes it only seems to use a single LED to flash.
When it uses dual sometimes it reboots the phone and then takes forever to load back up. Very strange.
Glad to see I'm not alone, Its a shame my first post is a bug!

The same happened to me. Didn't happen again and hasn't happened on my second device.

Thanks for your replies. Guess I won't return it, will go back to HTC Support and hope that they address this

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.
https://code.google.com/p/android/issues/detail?id=61873
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.

Nexus 5 extremely slow and stutter from boot after screen replacement

Hi, I replaced myself the screen (preassembled screen+digitizer+frame). After the replacement everything worked perfectly for like two hours when i rebooted it, from then on it is extremely laggy and stutters from boot animation, and when I press the power button (or when the screen shuts down), the phone itself shut down. In bootloader it doesn't seem to have problems.
I checked every connection inside the device (I've disassembled ad reassembled it several times).. thinking of a software problem, I've flashed marshmallow stock rom frist, and kitkat 4.4.4 then... but it's the same with any factory image.
Maybe I damaged something on the mainboard?
I also made a video to explain the problem:
with a lot of patience I set up a google account and downloaded cpu-z to see if maybe temperature sensor where giving wrong information to the system, but they're fine and everything seems to work propely aside from the stutter.
thanks to anyone who will help me, I'm almost giving up

It's probably touch lag from the new screen, u probably got a bad one, contact who sold it to u, get a new one

I thought of that, but the fact that the haptic feedback (like the one you have entering app drawer, or returning home) is perfectly sync without lags made me think the touch was ok... and even twrp recovery was working smoothly (coudn't show in the video since I factory flashed kitkat)

with 6.0 shuts down after boot animation (and reproduces it stuttered like the kitkat one in the video).
Right after the screen replacement, stock marshmallow was working fine for a while

That's very strange indeed, OK so try this, go into developer setting and check disable HW overlays, and check force GPU rendering, this will make the phone use the GPU for UI stuff, possibly fixing ur studdar, let me kno

OK, I've just tried... can't tell any differences.
I was thinking that the main way to solve this could be to investigate on the fact that turning off the display (both with power button or by itself after 30sec), shuts down the entire device. Could this be an hardware failure? (maybe generated by a physical damage that I caused)
thank you BTW

That's very weird, what did u replace, and how did u do the replace, did u do the frame as well, and when u took the batt out did it come out easy it did u fight with it, I've heard cases of this happening, and other issues caused by damaging the battery during a fix
PS, no problem man, I know exactly how u feel lol

I bought a pre-assembled frame-display-touch. The battery came out easily even if I slightly forced it in the bottom. Anyway before replacement the battery was completely discharged... it has been completely discharged for almost two months since I broke the lcd in September. Left the phone disassembled on the desk for two days. After reassemble I plugged in a 2A Samsung charger to fill it up... initially everything was working properly, made a few photos with both cameras to check, a call and some random checks.. still on charge. On the second call I made, the microphone stopped working, so was the third... turned off the device, back on and everything was messed up like it is now.
Well a battery failure could actually make sense...

hey i have exactly the same problem with my nexus 5, i haven't opened it neither changed battery or screen but i'm suffering the same issue since a few days ago. have you managed to find a fix?. in my case it just started to do that suddenly. as in the video is totally unusable, i reinstalled latest stock firmware throught the recovery menu but with no luck, everything is ultra slow now

I didn't fix it eventually... but from my experience in fixing PCs, I believe that it could actually be a power issue related to either the battery or some power circuit.
If you've nothing to lose and some dollars to spend, you could try a new battery and see if it works!
