Thanks for your answer.
I mean that the phone is ringing, but there are no buttons displayed to accept or reject the call. But every permissions are ON for the phone app. Also, every app has all permissions (I have very few apps in my phone so I don’t care about privacy).
The compilation number is: 8901.2.A.0111.20200131 (read from my phone)·
That’s not the only one issue. Since the first day, the sound deactivate whenever it wants so, at first I could answer the call but nobody hears me and I could not hear anyone. Also was the same for whatsapp audios and other multimedia audio as youtube.
If I restart the phone it usually takes a few tries because the screen shows strange colors or flickers. Sometimes everything goes well with the phone, but I don’t know when I could not answer someone or the screen will become to do strange things.
I have disarmed the phone and disconnected and reconnected the screen. Everything looked well.
I have having issues since the phone arrived in last october and is very tiring…
