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?

You can have a try: Go to the dial interface and dial "*#87#".
Or you can contact our professional after-sales directly.

I had the same experience at the beginning. If I will notice it again I will comment here.

Hi everyone! I have also noticed the "Flic"ing sound coming from the phone when you're using the thermal camera. If you noticed, the sound also happens when you click on the thermal calibration button and when you change to and from high-temp mode. From what I can infer, the "Flic"ing sound is the thermal camera recalibrating/adjusting the sensor position for optimal read-outs. It's perfectly normal and there is nothing to worry about!
