I was using my phone as usual when this screen appeared: This device is lost Hi! I lost my phone. I will contact you later. Thank you for your understanding! Below is a button as Activate this device, but when I enter the password associated with my Mi account, the phone unlocks for a second then locks back up and an error message displays: Find device closed unexpectedly. Now I can't access my phone anymore . Can someone help please? Thanks P.S.: My phone is a Redmi 2, if that can help at all.
