@minous Hello welcome to this forum :)
First thing you will do is read this: https://meizufans.eu/forum/topic/2697/question-answer-guideline
We need information about your device, or we aren’t able to help you! So read this topic and do what it tells you to do.
Or nobody can help you here, as we have no information about your problem.
If you are an user from India try meizufans.in we are active there too.
