Latest known WhatsApp problems on iPhone 16
1
WhatsApp keeps lagging and feels slow on my iPhone 16 — how do I fix it?
First fully close WhatsApp (swipe up to the App Switcher and flick it away), then reopen it, and make sure you're on the latest version from the App Store. If lag persists, go to Settings > General > iPhone Storage > WhatsApp and tap Offload App to clear cached data, then reinstall — your chats stay safe if backup is on under WhatsApp > Settings > Chats > Chat Backup.

WhatsApp keeps freezing or hanging on my iPhone 16 — what should I do?
Hanging is usually a stale app session, so force-quit WhatsApp and restart the phone (hold the side button and either volume button, then slide to power off). If it still freezes when opening, delete and reinstall WhatsApp from the App Store — restore your history from the backup prompt during setup, and keep iOS updated under Settings > General > Software Update, since older builds caused these hangs.

WhatsApp won't work on cellular data on my iPhone 16 but works fine on Wi-Fi — how do I fix it?
Go to Settings > Cellular, scroll to the app list, and confirm the toggle next to WhatsApp is switched on, since it's easy to leave off after setup. Then open Settings > Cellular > Cellular Data Options > Data Mode and make sure Low Data Mode isn't selected, and toggle Airplane Mode on and off to reset the connection.

Is WhatsApp buggy on the iPhone 16 after the latest iOS update?
Many bugs right after an iOS upgrade come from WhatsApp not yet being patched for the new system, so update WhatsApp in the App Store first and reboot the phone. If glitches continue, offload and reinstall the app (Settings > General > iPhone Storage > WhatsApp) — this clears corrupted cache from the upgrade while keeping your backed-up chats intact.

5
WhatsApp images and videos look blurry or low-resolution on my iPhone 16 Pro — can I fix the quality?
By default WhatsApp compresses media, so go to WhatsApp > Settings > Storage and Data > Media Upload Quality and set it to HD to send sharper photos and videos. To receive in full quality, ask the sender to enable HD too, or share originals via Files or AirDrop, since the in-chat preview is always compressed regardless of the iPhone 16 Pro's display.

WhatsApp stopped working or won't let me log in after upgrading my iPhone 16 — what now?
After an upgrade, confirm you're running the newest WhatsApp from the App Store and that iOS is current under Settings > General > Software Update, since WhatsApp drops support for very old iOS versions. If login or verification fails, restart the phone and reinstall WhatsApp, then restore your chats from the backup prompt during setup. See how others solved this on Reddit

How to install WhatsApp on iPhone 16
1
Open the App Store
Unlock your iPhone 16 and tap the blue App Store icon on the Home Screen. WhatsApp is not preinstalled on any iPhone, so you install it from here.
2
Search for WhatsApp Messenger
Tap the Search tab at the bottom right, type WhatsApp Messenger, and confirm the publisher shows as WhatsApp Inc. so you don't download a copycat app.
3
Download and install
Tap Get, then authenticate with Face ID or Touch ID (or your Apple Account password). The app downloads to your Home Screen in a few seconds.
4
Verify your phone number
Open WhatsApp, accept the terms, and enter your phone number. If your iPhone 16 uses dual SIM, pick the line you want WhatsApp tied to, then enter the 6-digit code it sends by SMS — it usually fills in automatically.
5
Restore chats and finish setup
Sign in to iCloud with the same Apple Account to restore an existing chat backup, add your name and photo, and tap Allow for notifications so messages and calls arrive reliably.
Stay safe: only ever install WhatsApp from the official iOS source. The Download button above already points there — modified copies (GB/Plus/Aero WhatsApp) can get your number banned.
