As you probably know (https://faq.whatsapp.com/1150261202542208), Whatsapp is not going to support Android 4 phones from 23rd of October this year; the minimum supported Android version will be 5.0
I want to move and merge all my conversations and files from my old Android phone to my newer one (they both have been used with the same phone number).
Unfortunately, I don't have any Google Drive backups on the old phone. Also, I hadn't done any other transfer/migration to my latest phone. I remember that when I'd installed Whatsapp on my newer phone, the application stopped working on the older phone.
Old phone:
- Android 4.2.2 (Samsung Galaxy S Duos GT-S7562)
- Whatsapp 2.21.17.23 (installed from here);
- no Google Drive backups;
- WhatsApp is no longer working (only on the old phone), since I'd installed it on my latest phone;
- at some moment I had to install the Google Play Store 25.2.27-16 for the Whatsapp to continue running (installed from here; more here); it now displays "Your phone date is inaccurate! Adjust your clock and try again" (but the date displayed is correct)
New phone:
- Whatsapp 2.23.14.79
- Android 13; OneUI 5.1
Thank you very very very much!
