WhatsApp for Realme Narzo 60 Pro

Realme UI's aggressive battery management freezes WhatsApp in the background, which kills incoming call alerts. Go to Settings > Apps > App management > WhatsApp > Battery usage and set it to Allow background activity (turn off 'Allow app to sleep' / battery optimization), then under Settings > Apps > Special app access > Display over other apps, enable WhatsApp. Also open Recent apps, swipe down on the WhatsApp card (or tap the menu on it) and tap Lock so the system stops clearing it.

Newer Realme UI builds reset notification and background permissions, so re-grant them: go to Settings > Notification & status bar > Manage notifications, find WhatsApp and turn Allow notifications on, then set WhatsApp's battery usage to Allow background activity under Settings > Apps > App management > WhatsApp > Battery usage. If lag persists, clear WhatsApp's cache via Settings > Apps > App management > WhatsApp > Storage usage > Clear cache (this won't delete your chats). See how others solved this on Reddit

This is the proximity sensor (next to the earpiece) staying triggered after you move the phone away from your face, which is common on Realme devices. First remove any screen protector that covers the top of the screen and wipe the area near the earpiece, since dirt or a thick protector is the usual cause. As a quick workaround, press the power button once to wake the screen so you can end the call. If it keeps happening on every call, back up your data and contact Realme support, as it may be a faulty sensor needing recalibration or repair. See how others solved this on Reddit

Realme UI's background restrictions can throttle WhatsApp, so first make sure the app is fully updated via the Play Store > tap your profile > Manage apps & device. Then go to Settings > Apps > App management > WhatsApp > Data usage and enable Wi-Fi data, Mobile data and Background data, and turn off any Data Saver under Settings > Mobile network > Data usage > Data Saver. Setting WhatsApp's battery usage to Allow background activity also keeps downloads from pausing when the screen is off. See how others solved this on Reddit

It works well for simple WhatsApp use once you stop the system from killing the app in the background. Set WhatsApp's battery usage to Allow background activity (Settings > Apps > App management > WhatsApp > Battery usage), enable Settings > Apps > Special app access > Display over other apps for WhatsApp, and lock it in Recent apps so call notifications always come through. You can also enlarge text via Settings > Display & brightness > Font size and effect for easier reading. See how others solved this on Reddit
