You take your nice modern Android, you factory-reset it, and you give (or sell) it to a relative (or friend, or stranger). (In my case, “give” and “son”.) But when they turn it on they see a screen labeled “Verify your account” with text reading “This device was reset. To continue, sign in with a Google Account that was previously synced on this device.” Here’s one way to fix the problem.
You, the original owner, grab the phone.
Sign in with the primary account you used.
Say No to all the sync options you get offered (to save time).
Say No when asked if you want fingerprint protection, nodding at the text that warns you that if you bypass it, your device will be usable by a thief after reset. Wishing that it also pointed out that if you want to pass the device on, you need to unset this.
Factory reset again.
Give the device back to the intended recipient.
Otherwise… · Suppose you’re the person who received the phone. And for some reason this procedure isn’t available to you. As in, maybe you’re a thief. Or maybe you bought it from Some Guy At The Airport and didn’t double-check that it’d sign you in.
Well, if you poke around the net there are video instructions, most at a site named “RootJunky” (uh-huh), that instruct a thief how to overcome this feeble and annoying protection. But I’m not linking to them.
[This entry, obviously not of general interest, placed here for Google juice and to inform the increasing number of people who are going to think that using fingerprint protection, and then subsequently passing on a phone, are a perfectly natural pair of things to want to do.]
