Sure. I thought too... Will do that asap

Hey . I have updated the phone with the latest security patch. No more updates left.

Am still on one UI 3 and will try to hard reset. I heard samsung will send updates for these kind of problem.

Hey Thanks for the reply. It is restarting once in a week or twice in a day , very random. Settings for automatic restart are off.

Yes, it is smooth and Notification panel got changed , looking a bit wierd with its full window appearance when sliding down. Rest everything is fine. Double tap to lock has been activated and couple of clock types on lockscreen disappeared from me...
