So I stupidly left my phone unlocked near my brother and left the room I come back and he is using the flashlight. I get a little mad and think nothing of it, but later I see a message on my phone like an onscreen notification that has a timeout and appears over everything at the bottom of the screen. It read, "Joe-PC Disconnected" I was like uh oh, did he connect to my phone somehow. I try to question him but he puts on a facade. I'm worried that he has access to my phones files. Any ideas? PS. He hates me, so that makes it worse, obviously. PS. The attached pic shows the type of blue notification I mention above.
