My BV9800 PRO makes some strange sounds from time to time, it sounds like "tc tic", it is the same sound that the phone makes when the FLIR app is starting, like the camera is trying to focus.
But I heard that sound even when outside the FLIR app and even when the phone has the screen closed when the phone is locked. That happens like every 20-30 min I think.
And the phone battery drains faster than it should be, like 1.6 - 4%/hour with closed screen even with battery economy on.
What should I do?
