The same thing just started happening to my K3 keyboard a few days ago. It continually freezes and then reboots like 2 or 3 minutes later. It doesn't matter if I'm reading or not. It'll do it at screensaver screen too. The time between it freezing is very random. Sometime's it'll freeze up almost immediately after rebooting where I'll be navigating the book list and never make it back to the book I was reading. Sometimes I can read several pages before it freezes. Other times it'll last 30 minutes. I've been charging it overnight every night since this started. Before this I would charge it like once a month, maybe. I've factory reset it twice. I contacted Amazon today was offered a discounted refurb Touch as a replacement but I don't want a Touch
