Downloaded & installed yesterday night, so far no problems observed.
I noticed that after the update, when the night mode or battery saver is turned on and you open settings you see a notification that battery saver or night mode is on. Never noticed this before.
Thanks for your replies to my query. When we turn on night mode or internet it shows it in the settings from when ihave get my phone and one thing also that it was a security patch update. Lets wait for replies. Otherwise Thanks
