Why the photo sent by WhatsApp is blurry on the watch?

Hi Yakis,

Thanks for using Apple Support Communities. Does the same happen with any photos received using the Messages app?

If this only happens with WhatsApp photos specifically, we'd recommend using the guidance from If an app on your iPhone or iPad stops responding, closes unexpectedly, or won’t open. Although the troubleshooting there is for iPhone and iPad, it can help with Apple Watch apps as well since settings and data between the two are interconnected. Guidance is as follows.

1 Close and reopen the app

Force the app to close. Then open the app to see if it works as expected.

2 Restart your device

Restart your iPhone or restart your iPad. Then open the app to see if it works as expected.

3 Check for updates

To see if updates are available for the app, open the App Store, tap your profile icon, then scroll down to see if updates are available. If updates aren't available for the app, update the software on your iPhone or iPad.

4 Delete the app, then redownload it

Delete the app. When you do this, you might lose data that was stored in the app. Then redownload the app. Then check to see if the problem with the app is fixed.

If the same continues, it may be best to reach out to the app developer as they'll be in the best position to suggest any further troubleshooting. If you need any help finding their contact information, use the steps in How to contact an app developer.

Take care.
