Sometimes, Android 7.1 bug:iPhone cannot communicate with Pixel properly.
Pixel phones with pre-installed Android 7.1 recently released a fantastic Bug, and the screenshots sent from iPhone are eerily jagged, and the problem occurs only between iPhone and Pixel devices.
Pixel users said on Google Forum that they could not normally receive screenshots from iPhone phones, including, but not limited to, text messages, e-mails, three-party social APP, etc., but there was no abnormal problem when using iPhone6,iPhone6s.
Even in safe mode, the problem persists, which means that Bug clearly has nothing to do with third-party APP, and there is nothing unusual between iPhone and Android 7.0 Nougat or earlier, as if the crux of the problem is between Pixel phones or Android 7.1 Nougat and iPhone 7/7Plus.
It may be that there are some incompatibility problems between Android 7.0 Nougat and iPhone 7/7Plus, which makes it impossible for them to communicate with each other properly. No matter what kind of chat APP they change, some Pixel users also notice that the problem is intermittent, sometimes they can receive clear screenshots from iPhone 7/7Plus devices, sometimes they can't, but this doesn't happen very often.
Google has acknowledged the Bug flaw, and Android 7.1 Nougat users will have to put up with the current Bug for a while before it can be officially fixed.
