My friend's phone is lost for maybe a week. And I have a classmate that has the same characteristics of the phone. But how do I prove that my friend's phone is stolen by my classmate? Also the phone looks reformatted. How will I know that my friend's phone is stolen by my classmate? Do I need to use a locator? Or will I just get the IMEI of my friend's phone and compare it with my classmates phone? My classmate that has the same phone is really naughty and also bad. So I will not doubt anybody exept him. So what do you think? What will I do now? I really don't know what to do. Please help me. Hoping you'll help me. Thanks!
