Latest known WhatsApp problems on Samsung Galaxy S6 (CDMA)
1
Why does WhatsApp keep stopping or running slowly on my Galaxy S6 (CDMA)?
The S6 has limited RAM by today's standards, so close background apps and clear WhatsApp's cache under Settings > Apps > WhatsApp > Storage > Clear cache (do not pick Clear data, which wipes chats). Also free up internal storage and restart the phone, since a nearly full storage partition can make the app crash on launch. See how others solved this on Reddit
2
WhatsApp messages won't send over mobile data on my Galaxy S6 (CDMA)
On older CDMA Samsung models this is usually a data toggle or APN glitch: open Settings > Connections > Data usage and confirm Mobile data is on, then toggle Airplane mode off and on to re-register on the network. If it persists, go to Settings > Connections > Mobile networks > Access Point Names and reset to default, since WhatsApp needs a working data path even when calls and texts work fine.

3
WhatsApp drains my Galaxy S6 (CDMA) battery and the phone gets hot
The S6 has a non-removable battery that has aged, so reduce WhatsApp's load: open WhatsApp > Settings > Storage and data and turn off Media auto-download for photos and videos, which cuts constant background data and CPU use. You can also limit its background activity under Settings > Apps > WhatsApp > Battery (or Battery optimization), and lower screen brightness while chatting. See how others solved this on Reddit
4
Can I still install or update WhatsApp on a Galaxy S6 (CDMA) running old Android?
The S6's final update is Android 7.0 Nougat, which newer WhatsApp builds are starting to drop support for, so update via the Play Store while you still can. If the Play Store blocks the update, keep your current working version installed rather than uninstalling it, and back up chats first via WhatsApp > Settings > Chats > Chat backup to Google Drive so you don't lose history.

5
How do I move my WhatsApp chats off my old Galaxy S6 (CDMA) to a new phone?
Before switching, open WhatsApp > Settings > Chats > Chat backup and run a manual backup to Google Drive using the same Google account you'll use on the new device. On the new phone, install WhatsApp, verify the same phone number, and choose Restore when prompted, since the move only works if that Drive backup completed on the S6 first. See how others solved this on Reddit

WhatsApp voice calls cut out or fail on my Galaxy S6 (CDMA)
WhatsApp calls run over your data connection, which is weaker on aging CDMA hardware, so connect to a strong Wi-Fi network when possible and avoid switching between Wi-Fi and mobile data mid-call. Check Settings > Apps > WhatsApp > Permissions to confirm Microphone and Phone access are granted, and if calls keep dropping on cellular, toggle Airplane mode off and on to force a fresh network connection.

How to install WhatsApp on Samsung Galaxy S6 (CDMA)
1
Choose how to download
On your Samsung Galaxy S6 (CDMA) 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 S6 (CDMA) 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.
