WhatsApp for Pixel 6

WhatsApp's official iPhone-to-Android transfer only works during the Pixel's initial setup, so it's easiest on a newly reset phone. Connect your iPhone to the Pixel 6 with a USB-C-to-Lightning cable, start the Pixel setup wizard, choose to copy data from an iPhone, and when prompted scan the on-screen QR code with your iPhone and follow the WhatsApp transfer step. Make sure WhatsApp on the iPhone is updated first, and after setup open WhatsApp on the Pixel, verify the same phone number, and let it restore. If you've already finished setup, you'd need to factory reset to redo the wizard, or use a third-party tool, since there is no in-app 'move chats' option for iPhone sources.

Go to Settings > Apps > See all apps > Google Play Store > Storage & cache and tap Clear cache (Clear storage if it still fails), do the same for Google Play Services, then reboot the Pixel 6. If the download still stalls, uninstall the partial WhatsApp, confirm you have free storage and a stable connection, and reinstall from the Play Store. As a last resort, download the official APK from whatsapp.com/android in Chrome and allow installing from that source when prompted. See how others solved this on Reddit

First update WhatsApp from the Play Store, then clear its cache via Settings > Apps > See all apps > WhatsApp > Storage & cache > Clear cache (avoid Clear storage, which logs you out). If it keeps force-closing, open Settings > Apps > WhatsApp > App battery usage and set it to Unrestricted, and check Settings > System > System update, since older builds had crash bugs that newer WhatsApp and Android releases fixed.

System updates can reset permissions or tighten background limits, so open Settings > Apps > WhatsApp > Permissions and re-enable Notifications, Microphone, Camera and Contacts, then under Settings > Apps > WhatsApp > App battery usage set it to Unrestricted. Clear the cache via Storage & cache > Clear cache and reboot. If messaging or backups still misbehave, update WhatsApp from the Play Store, since a fresh app version usually resolves post-update breakage. See how others solved this on Reddit

WhatsApp uses its own in-app camera instead of the Pixel Camera app, so first grant access under Settings > Apps > WhatsApp > Permissions > Camera and update WhatsApp. For better quality, instead of shooting from the in-chat camera, tap the attachment (paperclip) icon and pick Gallery to send a photo already taken with the Pixel Camera, which keeps the phone's processing. You can also raise quality in WhatsApp > Settings > Storage and data > Media upload quality > Best quality (HD). See how others solved this on Reddit

This relies on the proximity sensor, so make sure no screen protector or case covers the top of the screen near the earpiece, then go to Settings > Apps > WhatsApp > Permissions and grant the relevant access, clear the cache under Storage & cache, and reboot. Update WhatsApp from the Play Store as well, since some Pixel 6 firmware versions needed a WhatsApp update to restore the raise-to-ear behavior. See how others solved this on Reddit
