I am using Samsung Galaxy S II. Recently I had upgraded to the latest firmware version using Samsung kies. The upgraded version is gingerbread 2.3.6.
Then the problem started. The Handset is rebooting intermittently. Reasons and duration unknown. Otherwise the handset works fine.
1) Any suggestions for rectification.
2) Can I downgrade the OS using samsung KIES
3) Will this downgrade cause lose of all applications.
