My niece's Android phone was stolen on the bus today, and it's not likely that it will be found. We withdrew phone service from it, but all her personal phone contact information, texts, and some apps with some personal information are on it. (I don't know what version of Android it is, but she got it new about 1 year ago.) Does withdrawing phone service remove her phone contacts from the phone, text messages, etc., or are they stored in the phone itself? Is there a way to wipe her phone? If the battery dies, will the existing memory be wiped? I don't know if she has a Google account, but if she does, can something be done from there to block access to her contacts and personal information? Any suggestions? Thank you!
