Hi everyone. I recently purchased a new phone and decided to do something nice and give my old phone (ZTE Maven) away to a friend of mine that needed a newer phone than what they had. And now I am afraid I didn't take enough time and make sure that everything had been wiped out. I followed the instructions I found online by pressing the volume up and power button to enter that menu and 'factory reset' it. When it was done I turned it on and it was the welcome screen as if I just took it out of the box. (At this point I didn't think to go any further and check to see if my text convos or photos or anything was actually deleted) I already gave my friend the phone and now I just kind of nervous/anxious about if she turns on the phone with her own sim in it if all my texts and pics whatnot will be on there. Any help to ease my mind will help. Thank you!
