Title:

iPhone 12 mini crash - Panic CPU x caller

Text:

Hi guys, after screen (LCD incell iTruColor) and battery replace my 12 mini started crashing randomly.
Trying to explain: take the phone, press power botton, see black screen with only the possibility to see time and date + widget (in white color) on lock screen and background total black. So, phone crash and restart, after that seems to be fine until a new crash in the same way.
It's not a port crash cause it doesn't appen every 3 min, but smth like every hour, less time o more.
I assumed that the cause could be screen or battery, what do u think about?
There's crash report by 3u tool (just first page).
Thanks

=== Update (09/29/23) ===
UPDATE: for the moment phone is on since 1 day without any crash (I've checked reports) so it's maybe a faulty screen.
I'll update when LCDs screens back in stock and let you know if with another screen I will fix my issue.
I will also put some information about if it's worth to replace an oled with an LCD or if I will have some problems.

+=== Update (10/06/23) ===
+UPDATE: got a new display (incell) and everything is fine, so it was just a faulty display.
