It doesn't matter what phone app I use, my phone wakes when I have the phone barely away from face and it wakes constantly by itself during the day. For a new phone, it has a lot of problems. Also, is there a way to get into engineer mode since I have tried all the "codes" to get in and it will not work. I'm simply trying to recalibrate the proximity sensor to less sensitive values.

Blackview answer: Hi Customer, please back-up your phone's data, then restore the phone into factory settings
Mine: Hello. Thank you for your answer. I back up my phone and before reset in factory settings I tried the preferences ( in french) settings reset and I had been successful without full reset for factory settings. I post a question on the user forum of Blackview but it is still in process for a week. Could you post the way I found to fix the problem for others users on the forum?
Thank you in advance

But no answer or post for 3 months...
And the issue happen 3 times since I bought 4 months ago...

The problem is an intermittent promixity sensor that doesn't work so the screen still is awake during calls and ear and face touch make not wanted actions on screen..
