Latest known WhatsApp problems on OnePlus 12R
1
Why does the OnePlus 12R kill WhatsApp in the background and delay my message notifications?
OxygenOS has aggressive battery management that freezes apps to save power. Go to Settings > Apps > App management > WhatsApp > Battery and choose "Unrestricted" (the equivalent of "Don't optimize"). Also turn on Auto-launch for WhatsApp, and under Settings > Battery > more settings disable "Sleep standby optimization" / deep optimization so WhatsApp can sync in real time.

I'm not getting WhatsApp call and video call notifications on my OnePlus 12R until I open the app. How do I fix it?
This is almost always background restriction blocking the incoming-call signal. Go to Settings > Apps > App management > WhatsApp > Battery and set it to "Unrestricted," then enable Auto-launch for WhatsApp. Inside WhatsApp, open Settings > Notifications and make sure call notifications and "Use high priority notifications" are on, and confirm WhatsApp's notification categories are allowed in Settings > Notifications & status bar.

My OnePlus 12R front camera doesn't work or shows a black screen on WhatsApp video calls. What's wrong?
First check Settings > Apps > App management > WhatsApp > Permissions and confirm Camera is allowed, then force-stop WhatsApp from the same App management screen so no other app is holding the camera. If the front cam still fails, clear WhatsApp's cache (App info > Storage usage > Clear cache) and update WhatsApp from the Play Store, since stale builds can break the camera after OxygenOS/Android updates.

WhatsApp keeps crashing on my OnePlus 12R after the Android 15 update. How do I stop it?
Start by updating WhatsApp to the latest version from the Play Store, since post-update crashes are usually fixed in newer builds. If it still crashes, clear the cache via Settings > Apps > App management > WhatsApp > Storage usage > Clear cache (not data). If that doesn't help, back up your chats to Google Drive, then uninstall and reinstall WhatsApp to rebuild it cleanly against Android 15. See how others solved this on Reddit
5
How do I transfer my WhatsApp chats and media to my new OnePlus 12R?
On your old phone, open WhatsApp > Settings > Chats > Chat backup and back up to Google Drive using the Google account you'll use on the OnePlus 12R. On the 12R, sign in with that same Google account, install WhatsApp from the Play Store, verify the same phone number, and tap "Restore" when prompted. If you're moving from an iPhone, use WhatsApp's official "Move to Android" flow with a USB-C cable instead, since iCloud backups aren't directly compatible. See how others solved this on Reddit
6
Can I record WhatsApp calls on the OnePlus 12R?
OxygenOS has no built-in WhatsApp call recorder, and Android blocks apps from capturing another app's internal call audio for privacy reasons, so a screen recorder generally can't capture the other person's voice cleanly. The common workaround is to put the call on speakerphone and use the OnePlus screen recorder with the microphone enabled, so the device picks up both voices acoustically. Audio quality varies, and recording calls may require the other party's consent depending on your local laws. See how others solved this on Reddit

How to install WhatsApp on OnePlus 12R
1
Choose how to download
On your OnePlus 12R you can get the official app two ways: from the Google Play Store — the easiest option, since it keeps WhatsApp updated automatically — or directly from the official website. You can download an APK file, by clicking a link “Download WhatsApp directly”.
2
Open WhatsApp
Launch WhatsApp from your home screen or app drawer and accept the Terms of Service to start setup.
3
Verify your phone number
Enter your phone number. If your OnePlus 12R 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.
4
Restore chats and finish setup
Restore your chat history from Google Drive (use the same Google account), 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 Android source. The Download button above already points there — modified copies (GB/Plus/Aero WhatsApp) can get your number banned.

Download takes forever for me ?

Sure, a slow download is usually the network. A stable wifi connection will speed it up a lot. Enjoy WhatsApp on your your phone!

Thanks for asking, if the store lets you install it, you are supported. Very old systems may eventually lose support though. Hope that helps!
