Well hanging of phones does not always depends on phone storage so...Check for some apps that you have installed that draining battery and apps like multiple accounts , parallel space that run on backgrounds and any app that is running on background and using a lot of data or go to any samsung store and tell your problem..😊😊
1.just go to device manager in settings memory and check clear 2. go to setting ->device manager->battery->battery usage->click on any app on your screen it will show optimise battery click on that search for one ui and remove it from optimization and again search for android system and remove that to from optimization this will surely work
