So I turn my phone off every night before I go to sleep and turn it back on in the mornings. But this morning, I think I accidentally pressed a wrong combination of buttons and activated some sort of process? I went to press the standby button (most right of the four) but I think my finger also depressed the ringer volume down button on the side of the phone. My phone was turned off, but after this it went to this white screen, which looked like the same one as when we had to do the ROM update. Then later I pressed menu, because it said to abort press menu. Then it started loading up like normal. Does anybody know of any combinations of buttons that does this sort of thing so I can avoid it in future?
