Spare me the go search comments please. I'm 73 and might not have time to go search . You should be fascinated that a geezer like me knows as much about Android as I do. My Galaxy Tab got real sluggish. I don't use it much so I decided to do a factory reset. My surprise was that it downloaded everything! I thought I could load stuff from the play store as I desired. My question is that my S5 is acting strange (esp re battery consumption) and I'm tempted to factory reset it too. But, if it downloads everything that is on it now, what do I gain? Suggestions welcome. Thanks in advance.
