I installed WhatsApp 2.11.431 on LG G4 phone with Android 8.1 Oreo, made a backup with Helium and ADB, after that reinstalled the latest version, and everything is ok, continue working as usual.
To clone WhatsApp without verification, moved the backup to a phone with Android 4.0.4, installed WhatsApp 2.11.431 with Helium, restored the backup, reinstalled the latest WhatsApp, and works really well, both phones with same WhatsApp.
Yesterday, made the same steps on a Samsung Galaxy A6 with Android 10, but when installing the latest WhatsApp, it requested phone verification, but the other 2 phones continue working ok.
Made similar test with other WhatsApp numbers in the same Android 10, backup, restore in Android 4.0.4 and work well.
I am really lost. I want to move my WhatsApp to the Android 10 phones. I can't do the verification because I am out of my country and the line don't have signal.
Android 8.1 rooted, Android 10 not rooted, Android 4.0.4 not rooted.
Why a backup from Android 8.1 doesn't work in Android 10 but work in Android 4.0.4? Any help?
