WhatsApp for Pixel 6 Pro

Make sure you have a stable Wi-Fi or mobile data connection and that your phone's date and time are set to automatic under Settings > System > Date & time. If the SMS code never arrives, wait the full timer and then tap 'Call me' instead, and confirm your SIM can receive texts normally. Re-entering your number with the correct country code prefix, or doing a fresh install from the Play Store, usually clears stubborn verification loops. See how others solved this on Reddit

First clear the Play Store's cache via Settings > Apps > See all apps > Google Play Store > Storage & cache > Clear cache, then make sure there's enough free space and that Google Play Store and Google Play services are both up to date. If it still fails, remove and re-add your Google account, or as a last resort sideload the official APK from whatsapp.com and allow installs from that source when prompted.

WhatsApp uses its own basic camera pipeline rather than the Pixel's, so update WhatsApp to the newest version from the Play Store, since later builds corrected the front-camera framing. Toggling between the front and rear cameras mid-call, or ending and restarting the call, often forces WhatsApp to re-initialize the selfie sensor at the correct field of view.

Clear WhatsApp's cache under Settings > Apps > See all apps > WhatsApp > Storage & cache > Clear cache, and set its battery usage to 'Unrestricted' under Settings > Apps > See all apps > WhatsApp > App battery usage. Trimming very large group chats and old media, plus rebooting after a system update, noticeably reduces the stutter on heavy chats. See how others solved this on Reddit

This is usually the proximity sensor not triggering, so clean the top of the screen near the sensor and remove or trim any thick screen protector covering it. Make sure WhatsApp is updated from the Play Store, then clear its cache under Settings > Apps > See all apps > WhatsApp > Storage & cache > Clear cache and reboot; locking and unlocking the screen also helps re-trigger the sensor. If it started after a Pixel feature drop, checking for the next WhatsApp or system update typically restores the raise-to-ear behavior. See how others solved this on Reddit

Set WhatsApp's battery usage to 'Unrestricted' under Settings > Apps > See all apps > WhatsApp > App battery usage, and confirm notifications are enabled both in Settings > Apps > See all apps > WhatsApp > Notifications and inside WhatsApp under its own Settings > Notifications. Also make sure Do Not Disturb isn't silencing the app, then toggle WhatsApp's notifications off and back on to re-register the channel. See how others solved this on Reddit
