Update Advisor can help check if an update is available for your phone and free up space to get you started.

It connects to the network to check for new updates, then helps you free up space for updates by recommending files that you can move to an SD card or OneDrive to make room for the update. After the update is completed, you can move the files back to your phone.

With the Update Advisor app, you can:
  • Move songs, podcasts, pictures and videos to your SD card.
  • Move songs, podcasts, pictures and videos to OneDrive.
  • Delete songs, podcasts, pictures and videos from your phone.

Get this app from Store on your phone.
