WhatsApp for Samsung Galaxy V Plus

On your old Android phone, open WhatsApp and go to Settings > Chats > Chat backup, sign in to Google Drive and run a fresh backup. Then on the Galaxy V Plus, install WhatsApp from the Play Store, verify the same phone number, and when prompted tap Restore so it pulls the backup from the same Google account. Make sure both phones use the identical Google account, or the backup will not appear. The phone number must also match the one used for the backup. See how others solved this on Reddit

iCloud WhatsApp backups cannot be read by Android, so use WhatsApp's official iOS-to-Android transfer, which must be done during the first-time setup of the V Plus. With both phones unlocked, connect them with a USB-C cable when Smart Switch prompts to copy data, keep the same phone number, and on the iPhone open the link/scan the QR code that WhatsApp shows to start the wired transfer. Let it finish before disconnecting. If you skip this during initial setup, you cannot run it later without factory resetting the V Plus and starting over. See how others solved this on Reddit

WhatsApp runs fully on One UI, including chat backups to Google Drive, so day-to-day messaging feels much like iOS. The main adjustment is backups: go to Settings > Chats > Chat backup, link Google Drive instead of iCloud, and set a backup frequency so nothing is lost. If notifications are delayed, exclude WhatsApp from battery optimization via Settings > Apps > WhatsApp > Battery > Unrestricted. See how others solved this on Reddit

WhatsApp on Galaxy Watch relies on the phone connection and notification sync rather than a fully standalone account login. First make sure WhatsApp on the V Plus is updated and allowed to run in the background (Settings > Apps > WhatsApp > Battery > Unrestricted), and that notifications are enabled for WhatsApp in the Galaxy Wearable app under Notifications. If alerts and replies still fail, restart both devices, confirm the watch and phone are paired in Galaxy Wearable, and reinstall the WhatsApp watch app from the Play Store on the watch. Note that on some Galaxy Watch models WhatsApp only mirrors notifications and quick replies rather than offering the full app. See how others solved this on Reddit

On a supported Galaxy Watch, open the Play Store on the watch, search for WhatsApp, and install it. Keep WhatsApp updated and signed in on the V Plus, and make sure the watch is paired in the Galaxy Wearable app on the phone. Once set up, you can view incoming WhatsApp messages and send quick replies (including dictated text) from the watch. Available features vary by watch model and software version.

On Galaxy Watches with the WhatsApp app installed you can play incoming voice notes through the watch speaker and record short voice replies with the watch microphone. If playback is silent, raise the watch media volume and confirm the watch isn't in a Do Not Disturb or theater mode. If voice notes appear but won't play or send, restart the watch, ensure WhatsApp on the V Plus is updated and running, and reinstall the WhatsApp watch app from the Play Store.
