I updated my phone yesterday and for the most part, it's been okay.. Definitely draining my battery quicker. And this may sound strange, but today I noticed that when I receive email from my Yahoo account, my flash for my camera goes off. But it does not when I get mail from my Gmail. Also my flash goes off when I receive a call. Other things I've noticed, for my messages, when I already respond to them and I out of them, it still says I have a message. I check again, thinking I've missed something, but no I haven't. Still says I have a message. I am always very skeptical about doing updates... but my notification kept coming back until I did it. Shouldn't this be optional??
