I have recently faced a problem on Android regarding the flashlight.

When the flashlight is turned 'on', the flashlight icon in the status bar gets highlighted.

When I am turning 'on' the flashlight, it is staying on for sometime and it automatically gets switched off suddenly after some time, but the icon in the status bar still stays highlighted, which indicates that the flashlight is turned on. Same thing happens for the front flashlight.

Can anybody say what can be the reason for this automatic and random turning off of the flashlight ?

Additional information : There is no fixed time interval for the automatic switch off, it is occuring randomly.

  • I have an opposite issue, my icon will remove itself from the menu all together and i can not turn off the flashlight.... I think android has issues with flash light apps at the best of times... The flash is just that, a flash... Using the LED as a torch is possible, however it's not really designed for it.. Usually overheating causes an issue etc... Most androids in my experience have issues with flash light torch apps.. Even the default Video recorder has limit's on certain device's... A custom application or widget might be an alternative, some apps can handle the flash intensity etc... – Gadget Guru Mar 7 at 10:10
  • Yes, heating of the flashlight may be a reason, but since I don't use my device so much, it does not get heated. Sometimes, even when the device is cold, the flashlight turns off just a few seconds after it has been turned on. – Puspam Adak Mar 7 at 10:21
  • As you have said, I have tried many apps, including my self-made apps, but it doesn't seems to solve the issue. Even when I turn on flashlight from the camera app, I face the same issue. – Puspam Adak Mar 7 at 10:27
  • Sounds like residue, have you used it near water or maybe splashed water on it... It sounds like some kind of short circuit – Gadget Guru Mar 7 at 10:38
  • If you have root access, Add these build props and try tweaking them..... ro.media.capture.flash=led ro.media.capture.flashMinV=3300000 ro.media.capture.torchIntensity=65 ro.media.capture.flashIntensity=70 – Gadget Guru Mar 7 at 10:41

I have got a technique to deal with this issue.

I have booted my phone into recovery mode and wiped android's cache partition from there. Since then, the flashlight issue seems to have flown away. I mean, now the flashlight is not automatically turning itself off.

@Zillinium, I think you should also try this method to deal with your issue. If that doesn't work, a system update or factory reset might do the trick, if there is no hardware problem.

  • It's very strange that the cache caused this issue... Anyway I'll give it a try. – Gadget Guru Mar 9 at 11:44
  • For me, it's not anything strange, because once after restarting my phone, I had noticed that the speaker was not working at all ! From then, I came to the conclusion that software bugs and corrupted cache can affect hardware performance. – Puspam Adak Mar 9 at 14:12
