Photos in gallery are blurry until I’ll zoom them.

Hey there Davids88n,

Thanks for reaching out to Apple Support Communities. We understand photos are appearing blurry after updating your girlfriend’s iPhone. We’ll be happy to help.

To verify, is this happening with new photos or just previous ones? Test by taking a new picture to verify.

In Settings > Photos is Optimize iPhone Storage enabled? If so, does disabling this option have any impact on this?

Also, try force closing Photos and restarting your iPhone with the steps here:

Test again after this and get back to us with the answers to the questions we asked if the issue continues. We’ll go from there. 

Take care.

Thanks for that clarification Davids88n,

Hey Davids88n,

Thanks for the update. So just to be sure we understand, the issue only occurs when posting your images in Instagram? If this is just happening with the one app, the steps in this article could lead to a resolution:

Kind regards.
