After updating October security patch, mobile running too slow, internet speed getting down, battery draining too fast. I tried wipe cache clearing, network setting reset, also tried all setting reset but no improvements. I can't imagine samsung day to day release update with full of bugs which decrease flagship devices performance and they have no solution for it. I'm getting tired of samsung now.
