Android also manages how apps u se RAM. it may cache some
things you’ve been u sing recentl y, for quicker a ccess if you n eed
them again, but it will era se the cache if it ne eds the RAM for n ew
activities.
You affect the way apps use inter nal storage directly and in di-
rectly in many ways—for exampl e, by:
• installing or uninstalling apps.
• Downloading les in Chr ome, Gmail, and ot her apps.
• Creating les (for example , by taking pictu res).
• Deleting downloaded  les or les you crea ted.
• Copying les betwe en your devi ce and a comp uter via USB o r
bluetooth.
