Since months I have that my N810 sometimes freezes and reboots during operation, just randomly, once in 1-2 days and sometimes even a few minutes after a deliberate reboot.
So I reflashed the device (which gave a considerable cleanup even after restoring my settings and reinstalling my favorite applications) and reformatted mmc2 (due to an allocation error which is discussed extensively in this forum).
And the problem still is there I noticed these random reboots again with the same frequency.
Or has the N810 a deliberate automatic reboot cycle by design ?
