does factory reset wipe all the app and data?
was thinking to try that but lazy to do those backup of data...
yes of course it wipes ur data and apps. if u have unifi then you can do it fast. i have to download all my song from spotify premium again to my internal storage which is around 10gb. spotify also one of the apps that will pause suddenly in the middle of playing song after update to pie and i got fed up and reset whole thing.
you can gain back same storage because although u upgrade from android nougat to oreo to pie, ur previous history still there, just like what window update does. so if you format ur phone you get back those storage. i already move my chat and contact to gmail, whatsapp backup to cloud and i dont use wechat. photos and videos all saved in my microsd 256gb samsung evo
so basically i use around 4 hours to setup my phone including dl apps that i had previously, linking gmail accs, google acc and so on. you can backup it to sony backup system as well which it will be backed up into micro sd or cloud.
