WhatsApp for Samsung Galaxy F54

WhatsApp shows everyone in your phone's contact list who also uses WhatsApp, so the numbers usually get added to Contacts by something syncing in the background, such as a Google account, a SIM-card import, or an app like Truecaller. Check Settings > Accounts and backup > Manage accounts to see which Google account is syncing contacts, and turn off Contacts sync for it if you don't want it. Then open Contacts > Manage contacts (or the three-dot menu) to review and delete unwanted entries. WhatsApp itself has no contact-sync toggle; it simply mirrors your phonebook, so cleaning Contacts and reopening WhatsApp refreshes its list. See how others solved this on Reddit

Samsung's stock video player on One UI doesn't support every codec (for example some HEVC/H.265 video or AC3/DTS audio streams), which is why certain WhatsApp clips fail. Install a free player like VLC or MX Player from the Play Store and open the clip with it, or use Open with > VLC from WhatsApp. For videos you record yourself, set the camera to the standard codec by opening Camera > Settings > Advanced video options and turning off the high-efficiency (HEVC) recording so shared videos stay widely playable.

One UI 7 reworked the Android share sheet and removed the row of direct-contact shortcuts that used to sit at the top. To share to a specific chat now, tap the WhatsApp icon in the share menu first, then pick the contact inside WhatsApp's own selection screen. Make sure WhatsApp still has Contacts access under Settings > Apps > WhatsApp > Permissions > Contacts, and sharing to WhatsApp regularly keeps it near the front of the app row in the share sheet.

WhatsApp applies its own automatic noise suppression to voice and video calls, and there is no manual noise-removal toggle in the app, so the call audio is largely handled by WhatsApp rather than the phone's dialer. For voice notes, the practical fix is to record in a quieter spot and hold the phone closer to your mouth. For regular (non-WhatsApp) calls, look on the in-call screen for any noise-reduction or voice-clarity option your firmware exposes during the call. See how others solved this on Reddit

On the old phone, back up first via WhatsApp > Settings > Chats > Chat backup and tap Back up using the Google account you'll use on the F54. On the new phone, add that same Google account in Settings > Accounts and backup > Manage accounts, then install WhatsApp from the Play Store, verify the same phone number, and tap Restore when prompted. Samsung Smart Switch can move general app data and media too, but for WhatsApp chats specifically the Google Drive restore is the most reliable method. See how others solved this on Reddit
