WhatsApp for Asus Zenfone 12 Ultra

WhatsApp encrypts its voice and video calls, so the built-in Phone app recorder in ZenUI cannot capture them and most screen recorders will only catch your own mic audio. The most reliable software workaround is a third-party call-recorder app from the Play Store (such as Cube ACR) with its in-app/VoIP recording mode enabled and accessibility permission granted, though results vary by Android version and WhatsApp update. For important calls, putting the phone on speaker and recording with a second device remains the only consistently clean method. See how others solved this on Reddit

Google restricts the accessibility APIs that call-recording apps rely on, and Asus's Phone app only records standard cellular calls in regions where it is legally permitted, never internet calls like WhatsApp. To check what is available, open the Phone app, tap the three-dot menu then Settings, and look for Call recording. If it is missing or greyed out it is disabled for your region, so you will need a Play Store recorder plus a separate device for WhatsApp specifically. See how others solved this on Reddit

This is almost always Asus's aggressive battery optimization killing WhatsApp in the background. Go to Settings > Apps > WhatsApp > Battery (or App battery usage) and set it to Unrestricted, then in Settings > Apps > WhatsApp make sure auto-start is allowed so the app can run in the background. Finally, in Settings > Apps > WhatsApp > Notifications, confirm the Calls channel is enabled and allowed to show on the lock screen and as pop-up alerts. See how others solved this on Reddit

ZenUI's power management suspends apps once the screen locks, which delays or blocks WhatsApp's incoming-call notifications. Open Settings > Apps > WhatsApp, set battery usage to Unrestricted, and allow auto-start so WhatsApp can wake the device. Also turn off 'Pause app activity if unused' for WhatsApp under Settings > Apps > WhatsApp > Permissions, then test a call with the screen off. See how others solved this on Reddit

WhatsApp heavily compresses its video stream and uses a lower-resolution camera mode for calls, so the selfie camera looks far softer than it does in the normal Camera app — this is a WhatsApp limitation, not a fault with your phone. Good, even lighting helps the most, and keeping WhatsApp updated from the Play Store ensures you get the latest camera handling. For sharp video, use the stock Camera app or a service that streams at a higher bitrate. See how others solved this on Reddit
