moho, Jun 18, 2019 : When my phone is ringing - someone is calling me, the display does not wake up? I installed the app TruPhone and "played" with settings, but I am not sure if this is the reason, because after the phone did not wake up, I unistalled the app and it was the same. Maybe some settings in the do not disturb? Or is it the upgrade of the OS, I really tried all settings and options??
