Answer 1

It is not possible for you to roll back updates. However, you could try resetting the phone.
Always remember to backup your phone before performing resets as your data may be lost.
First try these
*#7780# - Restore factory settings - resets all the settings to the default
*#7370# - Reformat your phone
If the above two don't work then try try the "3 finger deep reset" which is depress these three keys simultaneously "*" "3" "green phone" and then power on phone whilst keeping those same three keys depressed until you hear start-up tone.
This wipes everything in the Phone memory that is not part of the ROM.
