So after the most recent update, my phone is slower, taking more time between transitions, the signal is actually worse, which is a big problem for me because i already have 0 signal where i stay, to the point i have to step outside, down the stairs, and on the street to get any (it's great everywhere else though!), and also my battery life has started sucking. Has anyone had these problems? Is there a way to undo the update? The update before this made my phone work like a pro, and now this crap. Also, whenever i take a picture, i can't get it to show up. It can take up to minutes, and it's never done this before.
