Latest known WhatsApp problems on Samsung Galaxy S20 Ultra
1
Why doesn't the mic or rear camera work during WhatsApp video calls on my Galaxy S20 Ultra?
WhatsApp needs explicit hardware permissions on One UI, so go to Settings > Apps > WhatsApp > Permissions and confirm Microphone and Camera are both set to Allow. If the rear camera still fails, force-stop the app (Settings > Apps > WhatsApp > Force stop), clear its cache under Settings > Apps > WhatsApp > Storage, and update to the latest version from the Play Store, since older builds had camera-switch problems during calls.

2
Why am I not getting WhatsApp call notifications on my Galaxy S20?
One UI's battery optimization often suspends WhatsApp in the background, so go to Settings > Apps > WhatsApp > Battery and set it to Unrestricted. Then open WhatsApp > Settings > Notifications and make sure call notifications are enabled, and confirm the WhatsApp Calls category isn't silenced under Settings > Apps > WhatsApp > Notifications. See how others solved this on Reddit
3
Why is the volume so low during WhatsApp video calls on my Galaxy S20 Ultra?
During an active call, press the volume up key so the on-screen slider controls the call/media stream rather than the ringer, since they are separate channels on One UI. If it's still quiet, turn off Settings > Sounds and vibration > Volume > Media volume limiter, and disable any Bluetooth or hearing-enhancement features that may be routing audio away from the main speaker. See how others solved this on Reddit
4
Why can't I send images on WhatsApp after a software update on my Galaxy S20 Ultra?
Newer Android versions tightened media access, so go to Settings > Apps > WhatsApp > Permissions and set Photos and videos (or Files and media on older One UI) to Allow. If sending still hangs, clear WhatsApp's cache under Settings > Apps > WhatsApp > Storage and confirm Settings > Apps > WhatsApp > Mobile data allows background data use. See how others solved this on Reddit
5
Why have my WhatsApp notification sounds suddenly stopped on my Galaxy S20 Ultra?
First check that Do Not Disturb (and any Bedtime or Modes routine) isn't active under Settings > Notifications, then open WhatsApp > Settings > Notifications and re-select a sound for both Messages and Groups. If the sound keeps resetting to None, go to Settings > Apps > WhatsApp > Notifications, tap the relevant category, and reassign the tone there, since One UI's per-channel settings override the in-app choice. See how others solved this on Reddit
6
Why can't I see WhatsApp message content in notifications on my Galaxy S20 Ultra?
By default One UI can hide message text in notifications, so go to Settings > Notifications > Advanced settings > Notification pop-up style and make sure previews are shown, then check Settings > Lock screen > Notifications > Hide content is turned off so text appears on the lock screen. In WhatsApp, also open Settings > Notifications and enable Show preview so the sender and message text display. See how others solved this on Reddit

How to install WhatsApp on Samsung Galaxy S20 Ultra
1
Choose how to download
On your Samsung Galaxy S20 Ultra 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 S20 Ultra 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.

Hi! Only the official app here. Modified versions can get your account banned, so we never link to them. Happy chatting!

Make sure the number and country code are correct, then ask for a new code. A quick restart of the phone often helps too. Feel free to ask if you get stuck.
