Screen switch-off during calls, doesn't switch back on when trying to get to dialpad

[rp-x1]

Hi All,

I've noticed this happen a few times now on my handset (XT1622 - Dual SIM, direct from Moto UK) where during a call, I need to enter a number for a menu option (i.e. Dial '1' for sales, '2' for tech support, etc) bu the screen does not switch back on. This also means I'm not able to end calls. The only remedy appears to be to reboot the device with a long power button press.

Anyone else have similar issues?

Appears to have been a strange bug with the Moto app. I disabled 'flip for do not disturb' and 'pick up to stop ringing' and it stopped permanently blanking the screen. Switched them back on and it's still working :/
