bhai .....just read it carefully...I wrote for another users 👇bro ...actually we maximum people do a simple mistake that if any big update come then simply we download it by mobile data or through fluctuating wifi network..but it's not the actual procedure or recommended to download any os update..because a big update allaways need stable carrier and its impossible in India that you will get non fluctuating wifi or mobile data ..and android system update can't allow that ..so it can give incomplete software update by damaging software side ..then also you will be able to install that firmware but you will also welcome software holes with glitches which leads to poor battery backup, slow charging, app crush, ghost touch,poor camera performance like issues .....so if any big update come then allaways try to flash it ...thatswhy Samsung introduced smart switch apk long before that a software can be flashed which is actual and recommended procedure....if you don't know how to flash firmware then please visit Samsung service center and flash firmware from them at absolutely free of cost ...please take my words ...in future you will never suffered any of the problems in your device.....I allaways maintain that rules hence no problem in my s9 as well as old note 3 also .....I can play pubg like game in my old note3 even without any lag or device heat ....👍👍
