It looks like the latest Android 7.1 Nougat update is having some issues with an iPhone 7 Plus. According to a discussion on the Google’s product forum, there is a bug that distorts screenshots captured on an iPhone 7 Plus and sent to a Google Pixel and Pixel XL smartphone.
The problem seems to affect specifically the iPhone 7 Plus (it works fine with an iPhone 7 or older iPhone models) taking a screenshot from within an app (be it third-party or native app). Screenshots sent via the standard MMS app, or even Google Hangouts will get colour and dimension distortion, but screenshots of the iPhone’s home screen appears fine. Strangely, the problem does not occur when sent via other apps like Facebook Messenger, and does not occur in reverse when images are sent from a Pixel to an iPhone.

This could be a problem with the way image processing is handled on Android 7.1. The problem does not only infect Pixel devices, other users are reporting that their older Nexus 6 running on Android 7.1 are facing the same problem as well.
While this isn’t a major issue, it’s still very frustrating when you want to send a screenshot from an iPhone 7 Plus to a device running on Android 7.1. Until this problem gets fixed, if you are affected by this error, you’ll have no choice but to use other apps to send your screenshots over.
