My backlight on my keyboard is gone, the only way to make it work is to open the Brightest Flash Light app. After that, it will stay on till I turn the screen off again.. Whoopdeedoo. The in-pocket detection is also gone on my Droid 4 after the update. Not only that, my e-mail no longer works (always empty, even for the last 4 days, nevermind the fact that I have 20 emails in my email that I can see from my PC), the sync settings for email are GONE (can't adjust when to sync). No e-mail, no backlight, no in-pocket detection. I Factory Reset my phone, and nothing, now I get to reinstall apps and reapply peoples' contact photos. This update looks and feels AWESOME, but to make my phone useless in the dark when I'm in bed (which is the only time I use it other than at work), why? What is the point? I know the backlight is related to the in-pocket detection sensor being disabled (i don't even see the red infrared light in there anymore). I really don't want to send my phone in, I've had it since February and it still works awesome.
