It was working for the most of the day, now my back light won't come back on. I've tried battery pull a couple of times.

Anyone else with this problem?

Mine was working most of the day, then my backlight wouldnt turn off. Its killing my battery. Also I can not bring up the app switcher. (Tried both holding BB button and the BB button menu).

Battery pull fixed both these issues for a few hours, but then it happened again.

I had these EXACT same issues on .83 and .85. I've never had them on any other OS.

I haven't had it yet on .86. I also have yet to receive the dreaded media card error on .86 *knock on wood*

it's back on now, I'm not sure if it was because of the battery was low (45%) or was it the BB Light app. I deleted the app and then rebooted and my light came back on, and I was chargin the phone in the process of this.
