camera live feed shuts off

[GearGurl]

im running the app on my samsung a-10
the phone is running a custom OS - arrow os

the app works fine and the camara feed and flash works aswell but after some ideling the camera feed stops streaming.
[by ideling i mean not activly viewing the live feed it doesnt matter if there is a print ongoing or not]
i dont know if its an OS thing or an app thing and if need be i will switch to another os (it will jsut be annoying to do all the set up again lol)
