Gmail/G+ allows you to change the cover photo along with the profile photo. I already changed both. The profile photo will also be used in the Gmail app on most (every?) Android. But what about the cover photo? I don't want the Google default cover photo on my Gmail app.
I'm on a Samsung using Android 5.0. Gmail app is currently on 5.6.103338659.release.
Is there a way to change this?
