    Boot the phone into recovery mode and clear the cache.
    1. Power off phone.
    2. Power on phone whilst holding down the volume down button (this takes slightly longer to react than you would expect and after the initial splash screen goes blank for a slightly un-nerving amount of time. But just wait).
    3. Enter the PIN/Password you use to unlock the phone when prompted.
    4. Choose a language.
    5. Choose "Wipe data and cache" (don't worry this is only a path to a submenu, it won't delete your data).
    6. Choose "Wipe cache" (IMPORTANT - MAKE SURE YOU DON'T TAP ERASE EVERYTHING).
    7. It will confirm that you have selected clear cache and ask you to say YES.
    8. When it says success choose "Reboot"
    9. The night after doing this leave the phone on charge overnight.
