Latest known WhatsApp problems on Samsung Galaxy Note 20
1
Why am I not getting WhatsApp notifications on my Galaxy Note 20?
One UI's aggressive battery management is the usual culprit, so go to Settings > Apps > WhatsApp > Battery and set it to Unrestricted. Then check Settings > Apps > WhatsApp > Notifications is turned on and, inside WhatsApp, that Settings > Notifications has a sound and pop-up assigned for both messages and groups. If it still misses notifications, make sure WhatsApp is excluded from Settings > Battery and device care > Battery > Background usage limits (Sleeping/Deep sleeping apps).

WhatsApp voice messages and calls have no sound or the mic doesn't work on my Note 20
First confirm the mic permission is on under Settings > Apps > WhatsApp > Permissions > Microphone, and that no other app (a voice recorder, screen recorder, or earbud app) isn't holding the mic open in the background. If it persists, clear WhatsApp's cache via Settings > Apps > WhatsApp > Storage > Clear cache and restart the phone, since a stuck audio session usually clears after a reboot.

Why do my WhatsApp voice notes sound muffled or low quality on the Note 20?
Poor voice-note quality is usually a mic obstruction or noise-suppression issue, so clean the bottom mic hole and remove any case lip covering it, then test in a quiet room. If the distortion continues, disable any third-party call/audio enhancers and clear WhatsApp's cache (Settings > Apps > WhatsApp > Storage > Clear cache); holding the phone normally rather than on speakerphone also gives the cleanest capture.

WhatsApp freezes or locks up my Note 20 when I open it
A corrupted cache or an out-of-date build commonly causes freezing, so update WhatsApp in the Play Store, then go to Settings > Apps > WhatsApp > Storage > Clear cache (avoid Clear data, which logs you out). If it still hangs, free up internal storage and reboot, and as a last resort uninstall and reinstall WhatsApp, restoring your chats from the Google Drive backup during setup.

How do I move my WhatsApp chats and data off my Note 20 to a new phone?
In WhatsApp on the Note 20 go to Settings > Chats > Chat backup and run a backup to Google Drive using the same Google account you'll use on the new phone. On the new device, install WhatsApp, verify the same phone number, and when prompted choose Restore from Google Drive; for the rest of your apps and files, Samsung Smart Switch can transfer everything else over Wi-Fi or cable.

How to install WhatsApp on Samsung Galaxy Note 20
1
Choose how to download
On your Samsung Galaxy Note 20 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 Samsung Galaxy Note 20 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.
