Mine was running horribly slow after the ICS update. I finally did a factory reset last night. Huge difference. It is not lagging at all any more.
Factory result. What portions of memory actually get blown away.. all the internal 16GB that is not core OS?
I'm gunshy to to the reset. What about data files that app's put on the phone. aren't those wiped out.
I wish there was a junk cleaner. As I search throw folders i see so much "stuff" not which could be remnant from old apps.
And of course I have some games and would not really want to lose the "saved" data, especially for once that I purchased.
Wouldnt a factory reset result in that stuff being lost?
