Phone App keeps crashing and rebooting the phone

[minifamilie]

Hello the phone App keeps crashing with no reason.

Sometimes (often) when i try to make a phone call, the phone freezes and reboots, it's not possible to make a call.

@minifamilie I would suggest firstly looking at running the phone in Safe Mode first, this will determine if a 3rd party app is interfering with the process....let us know how you get on

You didn't do the '4k' mod no? Where the whole phone runs in 4K, instead of only in certain media. This would cause the dialer to crash the phone.

Or maybe a contact is corrupt?

yeah, my bet is on resolution set to 4K at all times.

I guess you have update your phone's system

My XZ Premium did the same thing after changing to 4K all the time. Just download another dialer from the Playstore, it solved my problem right away.

If you dont want the dialer crashing then change the resolution to 1890x3360 instead of 4k.
