We went to Disney World and the phone decided it did not like our fingerprints and locks up. It asks for a device password that we know nothing about. Apparently either the staff at the store set the password or they sold us a used phone instead of a new one. Either way, it needs a password, and it is not the phone's password, it is the device's password. If you don't enter the right password within a couple of tries, it deletes everything on the phone. We called OnePlus support on a different phone. They say there is nothing they or we can do and said only the owner of the phone can unlock it. Well, we are the owner of the phone. We can prove we own the phone. In fact, we are still making monthly payments on the phone. We guessed possible passwords using the passwords we usually use. The phone deletes our entire vacation. Everything. The phone itself is great, but it's a time bomb. OnePlus can delete your data at any time, simply because it doesn't recognize your sweaty fingerprint while on vacation.
