I can not change mu pin code

[Computerci]

I use my phone with a pin code right now for screen security but when I want to change my pin code settings close itself.

That's quite odd, this is what you could try: Boot in >>> safe mode

Hi @Computerci, sorry to hear about this.

Do I understand correctly that the settings application crashes as soon as you try changing the screen lock in your device? If that is the case, please follow the recommendation given by @uliwooly and if you still aren't able to change the screen lock, go to Settings > Apps > 3 dots in the top right corner > Show system > scroll down and find "Settings" > Storage > Clear data > OK.

Keep us posted!

I tried but it did not change. Still I have "Settings has stop" error   By the way, how can  "Boot in  safe mode"?
