this has been my #1 complaint as I go to answer the Storm and the answer key plays musical chairs from portrait to landsacpe and back and forth...I'm still on .75 hoping .148 fixes it. Also, somebody had an app where you can choose applications where the acc is able or disabled.
i just got used to using the hardkeys for answering the phone, but i think he's talking about the in-progress screen. no, it's not normal. only once have i had this happen to me and it locked up the phone. don't think i was on .148 at the time. required a batt pull to fix.
if this is happening a lot i'd recommend a wipe and fresh install. weak sauce, i know, but so it goes.
