Kir32 — Sat, 20 Apr 2019 08:14:16 GMT

Model H8266, IMEI 354 701 091 123 757
Occurs under the following conditions:
1) the phone must be completely locked (i.e., the screen is completely off and nothing is displayed on the screen);
2) only for incoming calls.
3) Adaptive brightness adjustment mode is on.
And after answering the phone starts to function normally (i.e. turn off the screen when offering to a part of the body) only if you answer the call and wait for about 10 seconds without touching the phone.
For outgoing calls or incoming calls, but with an unlocked screen, everything works clearly. And there are no false positives. Those. bringing the phone closer to your head at a distance of about 2cm. the screen turns off automatically.
a) The proximity sensor to the ear was tested successfully.
b) Safe mode - did not help.
c) The phone was reset to factory settings - did not help.
d) Software has been restored - did not help.
e) The phone has the latest software version.
f) The phone is not rooted.
g) There are no protective films and glasses on the screen.
h) Light sensor tested successfully.
Thank you in advance for your prompt response and help!
Do not offer me to give to the service center, please! (it is 1000 km away from me)
