This just started tonight.
If I take the battery out and put back - and then power up - then the phone goes through to the lock screen and I can swipe and see other things loading. Then soon after this it reboots.
After it reboots though it will not make it to the lock screen before rebooting again. And this will loop until I take the batery out.
I've tried safe mode but there was no difference.
I've tried connecting to Kies on my PC but it reboots before a connection is established.
