Hi
gpsk02@gmail.com,
How much time have you check it is stuck at 98% ?
Make sure you are on latest software version which is .78, you can check by
Go to setting => About => Software information.
You can check under safe mode.
Hold power button for 5 seconds => When the screen flashes with option => Press & hold power option => You will get an option to restart in safe mode.
Factory reset your phone once if this doesn't help.
