Well, I thought it was just me. Random reboots, usually while it's in my pocket.
Last weekend it cost me a whole bunch of pictures I had taken in the day -- they just disappeared after the reboot
I don't think it is a hardware issue, i had no problems before the KitKat update -- currently hating KitKat a lot!
Think I will go back to Jellybean as I am currently using my Note 2 again, simply cannot trust the GN3 at the moment. What a waste.
PS Tried a couple of custom ROMS (X-Note 12 & 13) but still the same issue.
Device: GN3 & GN2
ROM: X-Note 13
