WhatsApp for Samsung Galaxy Core Advance

First make a fresh backup on the Core Advance in WhatsApp under Settings > Chats > Chat backup > Back Up, signed in to the same Google account you'll use on the new phone. On the new device, install WhatsApp from the Play Store, verify the exact same phone number, and when prompted choose Restore from Google Drive so the chats download automatically. Because the Core Advance runs an older Android, keep both phones on Wi-Fi and confirm the Google Drive account matches, or the new phone won't see the backup. See how others solved this on Reddit

If you still have the app installed, check WhatsApp > Settings > Chats > Chat backup to see when the last Google Drive or local backup was made. To restore, uninstall and reinstall WhatsApp, verify your same number, and tap Restore when it detects the backup; if Google Drive shows nothing, look in the phone's internal storage under WhatsApp/Databases for a local msgstore.db.crypt file. Going forward, set Chat backup to a daily schedule so a recent copy always exists before chats vanish again. See how others solved this on Reddit

WhatsApp has no built-in message readout, so the practical way is to install a notification-reading app (such as one of the 'read notifications aloud' apps on the Play Store) and grant it Notification access under Settings > Apps > Special access > Notification access. That app then speaks new WhatsApp notifications through whatever audio is connected, including your Buds. Make sure WhatsApp notifications are turned on in Settings > Apps > WhatsApp > Notifications, otherwise nothing is triggered for the reader to announce. Note that Android's Select to Speak only reads text you point at on screen, so it won't auto-read incoming chats. See how others solved this on Reddit

WhatsApp voice notes and calls switch the Buds into a low-quality mono call profile, so first delete the pairing and re-pair the Buds in Settings > Connections > Bluetooth, then test a voice note. Also check that WhatsApp has microphone permission under Settings > Apps > WhatsApp > Permissions > Microphone, since a denied mic blocks recording entirely. If the mic still fails, record using the phone's built-in microphone instead, as some older Android Bluetooth stacks like the Core Advance's don't handle the Buds' mic profile cleanly.

A Galaxy Watch can show and let you dismiss WhatsApp call notifications, but it generally cannot fully answer a VoIP WhatsApp call with audio routed through the watch the way a regular phone call can. Make sure WhatsApp notifications are forwarded by enabling the app in the Galaxy Wearable app under Notifications, and answer the call on the Core Advance itself. For hands-free audio you can pair Bluetooth headphones to the phone, since the watch only mirrors WhatsApp notifications rather than acting as a call handset. See how others solved this on Reddit

AI-generated suggested replies are a newer Galaxy feature and won't appear on the Core Advance, which is too old to receive that One UI update. You can still get basic predictive text by opening Settings > General management > Samsung Keyboard settings and enabling Predictive text. For smarter reply suggestions, install Gboard from the Play Store, which shows suggested replies in its toolbar inside chat apps like WhatsApp on older Android versions.
