The only way that Whatsapp let you back up your chats is using by linking a Google account, but I’m not sure is there’s some workaround like a third parties apps that let you back up your chats.
I know that using a third parties apps to this purpose is unsafe, but I’m just giving an example.
yeah, it’s possible. I use SwiftBackup for that purpose (closed source with internet access disabled; requires root).
Can you please explain me how does that work? I mean, if I backup all my Whatsapp data and then I try to restore it on other phone, that would work just that easy?
I managed to back up my chats and then restore it after flashing a custom ROM (so technically “another phone”) that way. it just copies the entire app with all its settings and contents and then lets you restore it to that previous state.
fyi disabling internet access doesnt do shit if you give a program root permissions
