Touchscreen stop responding until lock / unlock

Sun Feb 02, 2020 4:55 pm

I bought I BV4000 Pro on October 2018, and it worked quite well until some weeks ago. 

Now, sometimes the touch screen stop working, and I have no response when tapping in any point. To come back working, I have to lock the phone (pressing the power button) and unlock it again; sometimes it works immediately, other times I have to one about one minute before touch screen work again. Side buttons (power when volume) always works, so I see that the phone is not freezed.

I already tried a factory reset, but the issue continued, also without installing custom applications.

The issue is more annoying when using some games, that before worked well, now the game continue but screen often stop responding and I have to lock / unlock many times.

There is something I can try to mitigate the issue?

PS: I tried to post this to Feedback (https://store.blackview.hk/en/feedback) but I always get an error "[color=#dc3545][size=85]Valid content is required."[/size][/color]
