WhatsApp for Pixel 8

This is a known regression tied to a Pixel update that affected microphone gain, leaving recorded voice messages and calls very faint to the other person. As a workaround, hold the phone with the bottom mic (near the charging port) uncovered and speak a little closer, or switch to speakerphone during calls; also check Settings > Apps > WhatsApp > Permissions > Microphone is set to Allow. If it persists, report it in WhatsApp Settings > Help > Contact us, since a full fix has to come from a Google or WhatsApp update. See how others solved this on Reddit

The Pixel's noise-suppression and mic-gain processing can clash with WhatsApp's own audio handling, producing muffled or over-amplified recordings. Make sure WhatsApp is fully updated from the Play Store, and try recording in a quiet room while holding the phone normally rather than right up to your mouth. Toggling Settings > Apps > WhatsApp > Permissions > Microphone off and back on, then restarting the phone, also clears the glitch for many users. See how others solved this on Reddit

Android's battery optimization is usually the culprit, putting WhatsApp to sleep and dropping its background notifications. Go to Settings > Apps > WhatsApp > App battery usage and set it to Unrestricted, then open Settings > Apps > WhatsApp > Notifications and confirm all categories are enabled. Also check that WhatsApp itself isn't muting the chats, and turn off Adaptive Battery under Settings > Battery if the problem continues. See how others solved this on Reddit

The Pixel saves photos in a wide color space (and sometimes Ultra HDR), but WhatsApp re-compresses them to a narrower sRGB profile, which flattens the vivid tones. To keep more quality, send the image as a Document (tap the attachment clip > Document instead of Gallery) so it isn't recompressed. You can also turn off Ultra HDR in the Pixel Camera app settings before shooting, since standard photos survive WhatsApp's compression with less color shift. See how others solved this on Reddit

WhatsApp doesn't fully scale with the system on the Pixel's high-resolution display, so text and chats can look cramped. Increase it under Settings > Display & touch > Display size and text, raising both the Font size and Display size sliders. Within WhatsApp you can also bump the in-app chat text up via Settings > Chats > Font size > Large. See how others solved this on Reddit

Yes — Android 15's Private Space lets you install a separate, isolated copy of WhatsApp with its own number. Set it up via Settings > Security & privacy > Private space, then install WhatsApp from the Play Store inside that space and register your second number. Note that the Private Space copy stops delivering notifications whenever the space is locked, so you'll need to unlock it to receive messages on that account. See how others solved this on Reddit
