4. Do a Factory Reset

I normally do not advice this method as a first course of action because in doing this, you risk losing files and other stuffs you have on the phone as this will turn the phone to new like when you just got the device. So backup your data before undertaking this step.

To perform a Factory Reset, there are two ways this can be achieved. Either through your phone settings> Backup and Reset > Factory data Reset. The other way is to shut down your device normally. Wait for a while and then hold down the Volume Up, Home and Power keys altogether until the phone vibrates.

Once it vibrates, let go of the Power key but still holding on the rest of the aforementioned keys. The moment the Android logo shows up on your phone, let go of the held keys. Follow the dialogue as shown or read post on this here, backup and do a Factory Reset.
