Samsung updates their own security update,now Security is more stronger then earlier..bcz yesterday i called Samsung care and they said they used higher bootlodder versions..so after update please wait 2-4 days then you feel the difference..after recent update to M10..their is so much battery drains in 3 days and now from 2 days its performing better..
Also, check the versions of apps like Contacts, Messages,Phone, My Files, keyboard etc. all of those apps are updated. 😊 therefore not only security patch update but also app updates that can't be updated through store.
