How stop bloatware reinstalled after factory reset? (2024)

I have the grand title of phone manager for a lot seniors here who use low cost android phones. I debloat their phones by doing Adb commands etc. Once in a while I need to factory reset the phones and these annoying bloat apps will come back and I have to redo the debloating process.

Is there a way to identify the dirty app (package) that reinstalls these junk apps after factory reset? For example, com.LG.Bloat.AutoInstall, then I can remove the package immediately after factory reset in airplane mode, eliminate the chance to have these bloat come back.

I understand each manufacturer uses different packages for this purpose. Would appreciate any input! Thanks,
