WhatsApp for Motorola Razr (2022)

During the Razr's first-time setup, choose 'Copy apps & data' and connect both phones with a cable or wirelessly, then sign in with the same Google account so apps and settings come across. For WhatsApp specifically, back up your chats first on the OLD phone in WhatsApp > Settings > Chats > Chat backup (to Google Drive, using the same Google account tied to the Razr). Then on the Razr, install WhatsApp, verify the same phone number, and tap Restore when prompted. If you've already finished setup, you can rerun the copy process from Settings > System > Reset options only after a factory reset, so it's worth getting the WhatsApp backup right before you start.

Forget the device in Settings > Connected devices > tap the gear next to the device > Forget, then re-pair from scratch, which clears the corrupted pairing profile that usually causes audio dropouts. You can also clear the Bluetooth cache via Settings > Apps > See all apps > tap the three-dot menu > Show system > Bluetooth > Storage & cache > Clear cache, then reboot. Finally, make sure the Razr is on the latest software in Settings > System > System update, since Motorola has pushed Bluetooth stability fixes for the Razr line.

First confirm WhatsApp has mic access in Settings > Apps > WhatsApp > Permissions > Microphone > Allow, then test the mic with the Recorder app to rule out a hardware fault. Muffled or distorted call audio on recent Motorola phones is often caused by another app holding the mic, so close or uninstall any third-party call-recording or voice-changer apps. Clearing WhatsApp's cache (Settings > Apps > WhatsApp > Storage & cache > Clear cache) and updating both WhatsApp and the system software in Settings > System > System update usually restores normal call audio.

The Razr uses Google Photos as its default gallery, so first make sure WhatsApp is allowed to save media: open WhatsApp > Settings > Chats and turn on 'Media visibility' (and check Storage and data > Media auto-download). This lets received images appear in your gallery. If pictures are still missing, open Google Photos > Library and confirm the 'WhatsApp Images' and 'WhatsApp' device folders are showing, since an unsynced or hidden folder is the usual cause. You can also install a separate gallery app from the Play Store if you prefer browsing local WhatsApp media folders directly. See how others solved this on Reddit

RCS lives in Google Messages, not WhatsApp, so open Messages > tap your profile picture > Messages settings > RCS chats and toggle it on, then wait for the status to read 'Connected.' If it stays stuck, clear the cache in Settings > Apps > Messages > Storage & cache > Clear cache and confirm your number is verified; on T-Mobile and similar carriers, re-seating the SIM or waiting up to 24 hours often finishes registration. WhatsApp is separate from RCS and will keep working independently over your data or Wi-Fi connection. See how others solved this on Reddit

Some warmth during long video calls is normal on slim foldables, but you can reduce it by lowering screen brightness, closing background apps, and taking off any thick case that traps heat. Clear WhatsApp's cache via Settings > Apps > WhatsApp > Storage & cache > Clear cache and keep both the app and system updated through Settings > System > System update, since Motorola ships optimization and bug fixes there. If the phone still gets buggy, restart it and check that battery saver is off (Settings > Battery), since it can throttle performance during calls. See how others solved this on Reddit
