Try to reset your phone
Im sorry, the text that said "camera in use" are not under the camera icon it's under the flashlight icon
This the second time i got this problem, the first time somehow it's just working again without me resetting my phone. I want to use this solution if there's no other way.
Try third camera app and see if this still happen
Still cant, it said "Failed to open Camera. Camera may be in use by another application?ID:0"
how about in safe mode?
I already try it, it still doesn't work
Its becoz some app opened in background is using camera , like whatsapp using camera and close is via swipe up but didn't closed it properly so situation like this is causing you issues , nothing wrong with software
try go clearing cache?
settings => advanced => mobile manager => cleanup
I already try this, its still doesnt fix the problem
But how do i know which app is causing the problem ?
Hi @diancasella ,
Does the issue appear on the stock camera only or on other camera apps (e,g. Instagram) as well?
You can try these troubleshooting steps:
1.Please try clearing cache & storage of Camera app (long press "Camera">App Info>Storage & memory>Clear cache/Clear storage), then if is also related to some app, try to re-install 3rd party camera apps and check again.
3. Also, if the error persist I will recommend you to try a Factory Reset. Please remember to back up your data before performing a factory reset.
Settings>System>Reset options>Erase all data(factory reset)
This also happen to another app. But, for now my camera somehow working again without me doing anything. I don't know what will i do if it happen again in the future.
