My new HTC Desire C screen does not turn off while charging. It is running ICS (Android version 4.0.3, HTC Sense version 4.0). I have went into Settings > Developer Tools > Stay Awake (OFF). It doesn't work. Screen timeout is set to 30 seconds.
I also downloaded and installed Extended Controls, but when I try to add the widget to the homescreen it tells me "Please reconnect your SD card first" (which is non-existent at the moment).
p.s. I downgraded from a Xperia Arc S in hopes of a simpler phone, and my god this Desire C is BAD.
