What should I do before I update the software of my phone?

Before you download and install a new software update on your phone, make sure your phone is ready for the update by doing the steps below.
  • Back up your phone data and files.

    Although they will be retained after the update, it's best to keep a backup.

    Important: If you're using a mobile app or computer software to back up data and files, check first if it will still be supported by the software update. If not, you may not be able to restore your data and files.
  • Go to Settings and check if your phone has enough memory.

    To check, do one of the following:

    • Tap System > Memory.
    • Tap Memory.
  • Charge your phone to more than 50%.
  • Connect to the Internet using a stable mobile data or Wi‍-Fi® connection.
