My New samsung galaxy a7 will suddenly pop up a white screen with the word "DRIVE" on the upper left. Before I can do anything it will revert back to whatever I'm doing and then revert back to the "drive" screen. The only "cure" is to restart and hope that it will go away, which it will.

I noticed that something is downloading while this is happening but I don't see anything download notifications.
