when i try to upgrade, my phone says "space not available" or "low memory." what do i do?

Muve Music, like other Android apps, requires 30MB of free space to successfully download and upgrade. Some phones have limited storage capacity. If you have received this error, you will need to remove some applications from your handset before continuing the upgrade process.

If you have pictures, videos, music, or any other files stored on your phone, moving those to your SD card/computer or deleting them from your phone will also free up memory.
