Hi @Krishna8

Welcome to the community 

Sorry top hear you're having this problem 

Can you test your phone in safe mode and see if you are then able to change the lock screen without an error?

Let me know

Thanks for the solution @ChloeS

But no it didn't work. 😐 i got a new probelm. My phone goes in a loop. It keeps turning on and off again and again. The restart process takes atleast 15-20 minutes to show my home screen. The white screen with sony written in midde of the screen stays and goes in a loop atleast for 15-20 minutes. After a while then my phone shows me the home screen. I did reset my phone but it too didn't work. 😐😐

Hi @Krishna8

Sorry to hear that 

When you say you reset the phone, how did you do this? Did you perform a factory data reset through the settings on the phone?

Let me know
