WhatsApp for Huawei P40 Pro

Yes. The P40 Pro has no Google services, and AppGallery doesn't host WhatsApp's installer directly, so the reliable route is to download the official APK from whatsapp.com/android in your browser, then open the downloaded file and allow installation when HarmonyOS warns about an unknown source. AppGallery's search may show a WhatsApp entry, but it just hands off to that same web download. Avoid third-party app stores or modified/cloned WhatsApp builds, since those can get your number banned. See how others solved this on Reddit

WhatsApp runs fine on the P40 Pro; the usual culprit for missed or delayed messages is aggressive power management. Go to Settings > Battery > App launch, find WhatsApp, switch it from Automatic to Manage manually, and enable Auto-launch, Secondary launch and Run in background. It also helps to lock WhatsApp in the recent-apps view so it isn't cleared. With background activity allowed, most people find it as stable as on any other phone.

On Huawei phones WhatsApp can't auto-update through the Play Store, so an installed copy eventually expires and refuses to open. The fix is to download the current official APK from whatsapp.com/android and install it over the top; your chats and settings stay intact because it's the same app, just a newer version. Reopen WhatsApp afterward to confirm it launches. To avoid this recurring, check whatsapp.com every few weeks and reinstall the latest APK before the old one lapses.

With no Google services the Google Drive backup option won't appear, so use the local backup. WhatsApp automatically writes a nightly database to internal storage (Android/media/com.whatsapp/WhatsApp/Databases on current versions, or WhatsApp/Databases on older ones), and you can force one via WhatsApp > Settings > Chats > Chat backup. To restore, make sure that Databases folder is in place before you reinstall, then choose Restore during setup. For safety, also copy the whole WhatsApp folder to a PC, or use Huawei's Phone Clone.

There's no Google Drive bridge since the P40 Pro can't create a Drive backup, so do it with the local backup. On the P40 Pro make a fresh backup (WhatsApp > Settings > Chats > Chat backup), then copy the entire WhatsApp folder (including Databases) from internal storage to the same path on the Samsung using a PC or USB cable. Install WhatsApp from the Play Store on the Samsung, verify the same number, and it will detect the local backup and offer Restore. If you only care about photos and videos, Samsung Smart Switch can copy the WhatsApp media folders. See how others solved this on Reddit

Because the P40 Pro can't read a Google Drive backup, transfer the local files instead. On the Samsung make a local backup (WhatsApp > Settings > Chats > Chat backup), then copy its WhatsApp folder (with the Databases subfolder) to the same location in the P40 Pro's internal storage via a PC or cable; Huawei's Phone Clone app can also copy WhatsApp data across. Install WhatsApp on the P40 Pro from the official APK, verify your number, and choose Restore so it reads the local backup. The folder must be in place before you finish setup, or the Restore option won't show. See how others solved this on Reddit
