I just experienced my first random reboot when switching my lockscreen wallpaper.:icon_eek:
When you were changing lockscreen wallpaper which option did you select when it RR'd?
The reason I ask is the only bug I found running beta 7 was it would not change lockscreen wallpaper from regular gallery but would from miui gallery.
I chose lockscreen gallery, picked the pic, then hit save it said saved as lockscreen wallpaper, then it rebooted. But once it turned back on it had the pic I chose. It hasn't happened sinse though:icon_eek:
Alittle different than I discovered but glad it's working may have just been one of those things???
