I have solution for screen freeze problem in np2
I just switched on my mobile but it didn’t responding to my touch , I think it’s a bug, I just frightened then I clicked both volume up button and power button for 1 minute then it restarted.
I thought finally restarted, but again it showing no command.
I did same process, then it showed some options I clicked power off button using power button.
Finally the phone restarted and phone screen also working.
I think it’s a software issue please solve this issue.
