WhatsApp for Pixel 8 Pro

This is a long-running complaint where WhatsApp voice notes recorded on Pixel devices come out tinny, muffled, or distorted compared to other phones. Before recording, make sure nothing (a case lip, finger, or screen protector) is covering the bottom microphone, and record in a quiet room. Then check Settings > Apps > WhatsApp > Permissions > Microphone to confirm access is granted, and clear the app cache via Settings > Apps > WhatsApp > Storage & cache > Clear cache. Keep both WhatsApp and your Pixel updated through the Play Store and Settings > System > System update, since Google and WhatsApp have addressed audio routing issues in past updates.

Many users reported a quiet-mic regression that appeared around the March 2025 update, where voice notes record at a noticeably low volume. As a workaround, hold the phone closer to your mouth while recording, and disconnect any paired Bluetooth earbuds first, since the phone may pick up the earbud mic instead of the handset mic. Confirm the mic permission under Settings > Apps > WhatsApp > Permissions > Microphone, then clear the cache via Settings > Apps > WhatsApp > Storage & cache > Clear cache. If it persists, reinstalling WhatsApp sometimes restores normal input levels. See how others solved this on Reddit

This is almost always Android's battery optimization killing WhatsApp's background connection. Go to Settings > Apps > WhatsApp > App battery usage and set it to Unrestricted, then open Settings > Apps > WhatsApp > Notifications and confirm all categories (messages, groups, calls) are enabled. Also check that Settings > Notifications > Do Not Disturb and any Modes/Bedtime schedule isn't silencing WhatsApp, and inside the app verify WhatsApp > Settings > Notifications has alerts switched on.

WhatsApp doesn't fully scale with the system display size on the large Pixel 8 Pro screen, so it can look cramped by default. Increase it system-wide via Settings > Display > Display size and text, raising both the Font size and Display size sliders. For chat text specifically, open WhatsApp > Settings > Chats > Font size and choose Large. Combining both makes the interface noticeably easier to read. See how others solved this on Reddit

The Pixel camera saves photos with Ultra HDR metadata, and WhatsApp strips that HDR information during its normal compression, leaving a duller SDR version on the receiving end. To avoid the recompression, send the picture as a Document (tap the paperclip > Document instead of Gallery) so the original file is preserved. You can also set WhatsApp > Settings > Storage and data > Media upload quality to HD. For important shots, turning off Ultra HDR in the Pixel Camera app settings before shooting reduces the color shift. See how others solved this on Reddit

The Pixel 8 Pro uses an under-display proximity sensor that can get stuck reading 'near,' keeping the screen off after you move the phone away from your ear. First clean the top of the screen and remove any thick screen protector or case lip near the sensor, then reboot the phone to let the sensor recalibrate. If it still misbehaves, clear WhatsApp's cache via Settings > Apps > WhatsApp > Storage & cache, and check Settings > System > System update, since Google has patched proximity-sensor glitches in past updates.
