WhatsApp for Samsung Galaxy M14

This block means WhatsApp detected a modified or unofficial build, so uninstall whatever copy you have and reinstall the official app from the Google Play Store only. If you had a working WhatsApp before, first back up your chats from inside the app via the three-dot menu > Settings > Chats > Chat backup, so they restore from Google Drive during setup. If you were already on the genuine Play Store version, update Google Play services and WhatsApp to the latest versions, since a very old build can trigger the same message.

First open WhatsApp > three-dot menu > Settings, tap your profile name at the top, and confirm your About text is actually filled in and saved. Then go to WhatsApp > Settings > Privacy > About and set it to "Everyone" or "My contacts" rather than "Nobody." If it still doesn't appear, remember About only shows to people who have your number saved as a contact, so confirm the person checking has actually added you. See how others solved this on Reddit

For a built-in tone, open WhatsApp > three-dot menu > Settings > Notifications and tap Notification tone under Messages or Group notifications. To use your own audio file, copy it into your phone's Notifications folder, then in One UI go to Settings > Apps > WhatsApp > Notifications, open the specific channel such as "Message notifications," tap Sound, and pick your file. You can also set a per-chat tone by opening a chat > three-dot menu > More > Custom notifications. See how others solved this on Reddit

On Android 14 the usual cause is an outdated APK, so install WhatsApp from the Google Play Store rather than a sideloaded file, because older APKs are blocked by the stricter install rules. If the Play Store itself errors, go to Settings > Apps > Google Play Store > Storage > Clear cache, make sure you have free storage, and set the date and time to automatic. If you genuinely must use the APK from whatsapp.com, download the newest version and grant install permission to your browser under Settings > Apps > Special access > Install unknown apps.

Update both WhatsApp and Google Play services to their latest versions in the Play Store, since a version mismatch is the most common trigger even on a genuine install. If it continues, clear WhatsApp's cache under Settings > Apps > WhatsApp > Storage > Clear cache (do not tap Clear data, which wipes chats), then restart the phone. As a last step, back up your chats to Google Drive, uninstall, and reinstall the current Play Store build. See how others solved this on Reddit

Those suggestions come from One UI's share-sheet (Direct Share), not from WhatsApp. The reliable way to remove them is to long-press a suggested contact in the share sheet and choose to remove or hide it, which stops that person reappearing. You can also reduce them by going to Settings > Apps, tapping the three-dot menu > Reset app preferences, or by clearing data for individual apps so they rebuild their suggestion list; note there is no single global on/off toggle for share suggestions in current One UI.
