my Samsung galaxy 4 tablet would not let me sign in without a password which I don't have.I did a factory reset and started from scratch again.3days later it happened again,I could not get in,so I did another factory reset.Tonight it happened again,do I do another factory reset or do I throw it in the bin and get another tablet?
