WhatsApp for iPhone 8

Your iPhone 8 stays supported because it can run iOS 16, which is well above WhatsApp's minimum required version. WhatsApp only drops devices stuck on very old iOS releases, so as long as you keep your iPhone 8 updated to iOS 16.7.x (the latest it supports) under Settings > General > Software Update, the app will keep working. The phones being cut off are older models like the iPhone 5s and 6 that are frozen on iOS 12 or earlier. See how others solved this on Reddit

First make sure you have a few GB free in Settings > General > iPhone Storage, since installs stall when storage is tight. If it still won't install, open Settings > General > iPhone Storage, tap the downloaded iOS update in the list, choose Delete Update, then go back to Settings > General > Software Update and let it re-download and install. If it keeps hanging over the air, plug the iPhone 8 into a computer and update through Finder (macOS Catalina or later) or iTunes instead, which bypasses the stuck OTA install entirely.

WhatsApp's support cut targets iPhones that cannot update past very old iOS — mainly the iPhone 5s, 6, and 6 Plus, which are stuck on iOS 12. The iPhone 8 is not affected because it runs iOS 16, so you can ignore those dropped-model warnings. Just confirm you're on the newest available release under Settings > General > Software Update to stay safely above the minimum. See how others solved this on Reddit

Realistically you have a good while left, since the iPhone 8 runs iOS 16 and WhatsApp's announced cutoffs only affect much older iOS versions on older hardware. Keep the phone on its final iOS 16.7.x release via Settings > General > Software Update and keep WhatsApp updated in the App Store, and you'll stay supported well beyond the older models being retired. Once Apple stops shipping security patches for iOS 16, that's the practical signal it's time to consider upgrading. See how others solved this on Reddit

Force-close WhatsApp by opening the app switcher (double-press the Home button on the iPhone 8) and swiping the app away, then restart the phone. If it still won't open, update WhatsApp in the App Store and make sure iOS is current under Settings > General > Software Update, since an outdated app on an older iOS build is the usual culprit. As a last resort, delete and reinstall WhatsApp — your chats restore from your iCloud backup during the setup steps. See how others solved this on Reddit

No, as long as you update past iOS 15. The iPhone 8 supports iOS 16.7.x, which is above the 15.4.1 line WhatsApp is retiring, so just install the latest update under Settings > General > Software Update. Only devices left stranded on iOS 15.4.1 or earlier would lose support, and your iPhone 8 is not one of them. See how others solved this on Reddit
