• An update package can be several megabytes in size, so it is recommended that you use a Wi-Fi connection. Wi-Fi connection is your phone’s default connection method.
  • Before starting the update, make sure your phone has enough battery power. If the phone battery level is too low, your phone will prompt you to charge the battery before starting the update.
  • It is also recommended that you create a backup before doing a software update. In Application menu, select Backup > New backup. Give a name for the backup, and additionally, select the location where backup will be stored and the data to be backed up.
  • Check that your phone is set to the correct time and date. With a wrong date or time, your phone won’t be able to access the updates.
  • Make enough space on your phone for the update. If necessary, remove some apps or other large items with App manager.
  • If you have problems during the software update, you can try our Discussions community to solve them.
