I've been searching the internet for a clear explanation on what makes iOS contact photos appear full screen vs. the smaller contact photos in the corner for incoming calls.
I would like my photos to appear full screen.
Using Photoshop I've created 1500px x 1500px square photos with the subject in the middle of the photo. The high resolution photos are stored in a 'contacts' album which I created in iPhoto and syncing via a manual sync of the iPhone to my Mac Book Pro. I then manually update my most contacted people with their high res photos from the local 'contacts' album.
My contacts are generally synced via gmail exchange, which may be automatically degrading the quality of my photos to 96px to 96px.
I'm not sure what's happening!
