Phone memory trouble?

[Tymme]

Go through your apps and make sure they're on the SD card ("move to SD" in the second set of boxes down the screen).

While you're doing this, also go into Gallery, the Play apps (Play Store, etc), Music, etc., and 'clear cache'. Often times there's download data that's forgotten and needs to be "swept clean". (Maybe do this for Facebook and Instagram, too, but that might lose queued posts/info.)

The number of apps you have does make a diff- even with everything on the SD card, you still have 20-80% of the app data on the phone itself. Removing stuff you don't use does help.
