An update to my phone that fixes, among other things, the Stagefright bug. I'm hoping it will also fix some lagging issues I've had in Android 5.1.1 Lollipop. Thank you, T-mobile. Wish me luck!PS: I fell asleep while it was updating, and two hours later awoke with the phone on my chest (no, it didn't take that long to update!) The lagging is gone, and the bug fixes apparently helped. Yay!
