Lock screen button

[Carillo]

I have my Sony Xperia M for like four months and i can't unlok it anymore.. I mean I can but only if i adjust tiny sticker that is attached to mobile device.. I dont know what to do.. I am afraid if i glue it that it wont gonna work anymore but if i dont glue it i have to adjust it every time cuz it is broken.. Should i go to Sony store and give my phone to them or what?

Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.

I suggest that you visit nearest service center to have your phone examined by a technician. You can contact your local support team for further information about how to proceed with this in the best possible way:
