I have a ZTE Axon 7. Starting 4 days ago, I have sporadically had a grey bar pop up just below the notifications bar on the home screen. The word "partners" is in white on the left hand side. When this happens, the screen freezes and nothing works except for the notifications which I can pull down. Clearing the notifications does not remove the "partners" bar. I can get rid of the "partners" bar temporarily by restarting the phone. Does anyone else have this problem? . I am hesitant to factory reset my phone is fully functional when I don't have the "partners" bar.
