To make sure a software update can be carried out smoothly and without interruptions, prepare your phone for the update.
Here's what you need to check.
If your battery level is low, give your phone a quick charge before starting the update.
Check how much free space you have on your phone and make some room for the update. To find out how to check the available storage, see
Checking phone storage.
If necessary, remove a few unwanted apps. Refer to
Uninstalling an app to see how it's done.
Or delete large files (such as photos, videos, or music) from your phone.
Make sure your phone is set with the correct date and time.
This determines which new updates you'll need. For details, see
Correcting the date and time.
