Picture with flashlight

Hi all,
I tried to put the flash (light) for a picture, and I have an issue... The flash is lightening before taking the picture, so it's useless ...
Do you have the same issue ?

When I turn my flashlight on it stays on until I turn it off.

It stays on, but it's brighter on the moment the picture is done.
I've tried to make photos in front of a mirror to see if it is lightening before taking the picture or not. In my device (HTC TyTN) the flash comes just at the right moment, so it's not useless, but the shooter sound comes about 1 second after the picture is really taken.
Do you have a lot of applications running? probably your device is running slow and that's why you're experiencing this. Are you experiencing the same issue just after a hard reset?

Yes maybe, I'm going to try the mirror test

I have the same problem
The flash light it is NOT syncronized with the capture moment.

I think the question here should be;
When is the capture moment?
Pressing of the button does not coincide with the shutter sound or flash lighting... This is probably as the flash lights when button is pressed, at which point the device starts image transfer and the shutter sounds after picture is complete (try moving camera after shutter has sounded and before)

screen stays black after standby

have android desire build on my hd2 and it works great...if i put my phone in standby for a few seconds it comes back on just fine but if its in standby for a few minutes only the keys light up and i have to pull the battery..i was reading some posts and thought i saw something about deleting the data.img....was wondering if this was the solution to the problem or something else..

If you have a black screen and the button lights are on, you can stick it under a bright light and turn it on. It should come on after that. If that's the case then turn off automatic brightness and see if that corrects the issue.

auto brightness wasnt on when i went to go change it...i flipped to it just to see if it would do it but it does the same thing..if in standby for too long,the buttons light up and the screen lights up black but thats it.

pink/white camera fix

I've had a problem off and on, sometimes the camera stops working and flashes pink and white instead of showing the preview image. (flash & other icons still remain on the screen--if you try to snap a photo it sometimes turns on the flash and keeps it on--sometimes a bright light such as light bulb or sun will sort of show up--restarting often does not help)
here is the problem: the shutter is not opening. It might be opening a little, but not all the way. You might hear it click.
Here is the (a) fix: smack your camera. Forwards or backwards, using the palm of your hand. Moderate strength.
If there is a more elegant fix, I'd like to hear.

might need to replace the camera it self. sounds like a hardware failure. :'(

Screenshots never show hardware issues (i.e dead pixels, red screen issue, etc), as they are generated by software. You should take a shot of your screen with an external camera instead a screenshot.

A5 2016 sometimes won't wake up, screen flashes

Hi,
I have this phone for little over 2 years. For over 1 week now I'm experiencing my phone not being able to wake up when I use the power button/home button. Whenever I push the button, the screen flashes for like 1s blue color, you can also see that the notification panel is blacked out and part of it green and it doesn't wake up. Sometimes it doesn't even flash. It used to take about 10 tries to wake it up but today I couldn't wake it up. I performed soft reset, I couldn't see the booting animation at all but it rebooted, buttons lit up and I was able to get in. It's like the phone is working fine in the background but the screen doesn't light up. I can turn down/up the volume, take a screenshot, get into settings, open apps, write a message but the screen is black. Even my alarm went off this morning but I couldn't dismiss it.
I downloaded an Always On Display app. Although I don't actually see the screensaver when it's locked, it's still on and it's easy to get in beacuse of it.
It all started with the screen flickering on minimum brightness. In February this year I had the screen replaced for the same issue but this time it's worse because of the blacked out screen.
Any ideas what it could be? Faulty display again?
Thank you

It's over to have this phone for little over 2 years now you should have to change
TIP:
Flash a new stock rom of your phone from sammobile via ODIN.

That would be great, but I'm not a person that buys new phone every 2 years. I was thinking about it though .
When it comes to flashing. Do you think that would help? I don't want to end up with a black screen unable to set the phone up again. Cause overall it's working great .

Hi, i have the same problem, i'm from Belgium, and I have blinking screen problem and wake up screen problem :s
is it a software issue (nougat???)
before the big update (marshmallow i dont have any problem)
i'm on firmware A510FXXS7CRJ6_A510FLUX7CRJ1_A510FXXU7CRJ6_HOME.tar.md5

Turn screen brightness up abit to stop the blinking of screen. It's an issue of the screen hardware itself at low brightness after wear and tear. As for the hanging issue, maybe it has to do with your AOD app? Try uninstalling the AOD app OR flashing a stock Rom OR custom rom OR factory reset and use your phone at a higher brightness that the screen does not blink and see whether it still persists.

Thanks, because of my past experience with the same problem earlier this year I know about that "solution". Unfortunately, it makes the battery die faster as expected. Which is sad because I used it mainly on low brightness. So it's really not a solution at all.
I got rid of the AOD app because I found out that the phone lights up on 2nd try. AOD didn't work at all. I have to wake it up, put it to sleep and wake it up again which is always successful and the screen lights up. The screen flashes white about 3 times in a row now otherwise it works.
I haven't flashed it yet although I wanted to. But I will see what can I do. Thank you though!

I'm having the exact same issue using LineageOS.

It's already been 2 years, but since this thread is one of the first results on Google, I'll gladly add a solution.
Exact same problem for me, went through two screen repairs under warranty, and it would always come back a year later. No difference between Samsung OS and LineageOS, though I haven't tried rooting it.
Found on Ifixit: this issue is related to the AMOLED screen technology used by Samsung (among others). You can look it up, apparently there is a bad (?) voltage management in low brightness which worsen with time.
I could fix it with the "OLED Saver" application on Play Store. It works around this voltage management and allows you to reduce the brightness without the green flickering.
I still got white flashes after the installation, but not anymore the day after. I could even disable this application without the issue coming back.
I don't know what kind of magic cleanup this app performed, but it really is a (screen) life saver.
