I downloaded an app called paperize that changes home wallpaper automatically each hour from a folder with hundreds of wallpapers.. I set the app to auto start, set the system to ignore battery saving for the app, locked the app so it doesn't close, set the system to not automatically manage app activity, gave the app all the permissions it needs.. and yet it only works for a few hours and then stops working, the system says nothing and confirm that the app is running in the background but it has no activity.. I tried another similar app called peristyle, then another called wallpaper changer, then wallflow.. I'm running out of wallpaper apps on the store and they all just stop working after about 24 hours or so.. never had this issue with any of the apps on my older phone which had xiaomi hyper os, or my older pixel which had stock android.. I need some workaround or a hidden setting that I might have missed or maybe a vivo system alternative which can use my own set of wallpapers instead of online downloads
