WhatsApp for iPhone 12

No, the iPhone 12 is safe. WhatsApp is only dropping support for iPhones stuck on very old iOS versions (iOS 15.1 and earlier, such as the iPhone 5s, 6, and 6 Plus). The iPhone 12 runs iOS 16, 17, and 18, so it stays fully supported. Just keep the app updated from the App Store and you'll continue getting new features. See how others solved this on Reddit

This happens when a new WhatsApp build requires a newer iOS than you currently have. On your iPhone 12 go to Settings > General > Software Update and install the latest iOS (the 12 supports up to iOS 18), then reopen the App Store and update WhatsApp. If the App Store still blocks you, tap your profile icon at the top, scroll to find WhatsApp in the list of available updates, and retry the update there.

Force-close the app first by swiping up from the bottom of the screen and flicking the WhatsApp card away, then reopen it. If it still hangs, restart the phone (press and hold the side button plus a volume button until the power-off slider appears, then power back on) and confirm WhatsApp is fully updated in the App Store. If a reinstall is needed, set up an iCloud or local chat backup first (WhatsApp > Settings > Chats > Chat Backup) so your messages can be restored, since deleting the app without a current backup will lose your chat history.

Clear out heavy storage in WhatsApp > Settings > Storage and Data > Manage Storage, where you can delete large videos and forwarded media that bog the app down. Also turn off auto-download under Storage and Data, and try offloading then reinstalling the app via Settings > General > iPhone Storage > WhatsApp if the slowness persists (set up a chat backup first). Making sure both iOS and WhatsApp are on their latest versions usually restores normal speed. See how others solved this on Reddit

The extra entries are usually leftover app data or caches, not separate copies of the app eating real space. Open Settings > General > iPhone Storage > WhatsApp and tap Offload App, which removes the app but keeps its data. If a duplicate listing remains, back up your chats (WhatsApp > Settings > Chats > Chat Backup), then delete and reinstall WhatsApp once from the App Store to consolidate the entries while keeping your account and chats.

Check Settings > Notifications > WhatsApp and make sure Allow Notifications, Lock Screen, and Banners are all on, then verify Background App Refresh is enabled in Settings > General > Background App Refresh. Inside the app, go to WhatsApp > Settings > Notifications and confirm message alerts are turned on. If messages only arrive when you open the app, disabling Low Power Mode in Settings > Battery often fixes the delayed delivery. See how others solved this on Reddit
