You'll need to have some free space available on your Galaxy S10, Galaxy S10+, or Galaxy S10e to properly install the Android 10 beta.
The Android 10 beta is around 1.8GB for the Galaxy S10e, 1.8GB for the Galaxy S10, and around 1.9 GB for the Galaxy S10+. If you don't have that kind of room available you'll need to delete or move around some files in order to make room. |
