I have lost my phone and I used the Samsung account to locate it, but it didn't work. Also, I told the police using the IMEI number of the phone. In the same day I looked into Android Device Manager, but it showed nothing. Even it being stolen on 4/5 and the phone turned on on 8/5 because my friend saw my Viber account once. Can I at least locate the last time my phone was turned on to find my phone?
