Hear me out. I know that this has been asked before, but I am hoping that there might be a workaround or some new information.
My boyfriend has a [Phone X] that has been sent in for replacement twice, and he now has two [Phone X] registered to his google account, and neither one of them is his newest phone.
This is the weird part: somebody has one of his old phones and is using it. He can see everything they download and install onto the phone.
What is going ON here? I know it is possible to "hide" that phone, but it just does not seem good enough, from a security standpoint. His android market account is connected to a google wallet account.
((I am the one asking because I am more interested in tech and more patient about troubleshooting.))
