Got a second hand phone and has activation lock. What to do?

If there is any way that you can contact the original owner you could have them remove it from their apple account or if you can convince apple that the device is legally yours then they might remove it. Whatever you do, definitely do not buy any programs that claim to remove it because none of them work

Sorry but you probably have a paperweight. Apple won’t do anything apart from take it as lost or stolen. As above if you got it from the owner ask them to remove the account. If not your out of luck.
