First pass:
- Go to Settings > Storage Then tap on "Apps" under Total Space Heading.
- Then tap "Clear cache".
- And Total cache memory should show 0.00B when done.
Second pass if need more memory. If you need more memory even after doing the above then you will need to move apps to :
- You need to try moving apps to an external storage. Check out my article for How to Free Up Memory on Android Phone.
- You need to try find some apps you are not using or in need of that you can uninstall from you Android phone. However, I don't know about your phone but on mine:
You cannot really uninstall any of the apps the phone came with b/c even if you uninstalled them it would just remove all the updates from it & reinstall the factory version of the app it came with.
Good luck!
