@WO1F Your two problems seem related, maybe you have a screen protector?

[WO1F]

Yes i have , but without it  phone can scratch easy  isn't

It can, but you can always place a thin one instead. Is it protective glass?

[WO1F]

Yes its glass screen protector,    what you advise me to do please

Remove it, the screen does not behave too well. There are good screen protectors, but many times what you experience right now happens.

I removed it and i will test my phone today  because normally befor some time it was ok and some times it was have the 2 problem  so i will test today and i will update you, and thanks for help  i appreciate  . But you think it's screen glass problem not software or phone issues. ? 

Olso when i log in sony support site  it shown my mobile as sony z5 dual but imei it written missing and warranty none.  How this ? Is it because of 2 imei number !

Yes, my bet would be on the screen protector.

Related to your account, I don't have access there, so you need to get in touch with your Local support.
