I just received my TinyScreen+ yesterday.  Once I plugged in the USB cord, Flappy Birds immediately came up.  I was able to "play" the game but noticed that screen brightness kept going from high to low and back.  Is this normal or is my unit defective?

Never mind. Been pushing the wrong button while resetting.  Now everything works.

Can you explain further? I *just* plugged mine in for the first time, and am seeing the same thing. Even without pushing buttons, or attempting to reset...

It's programmed to do so, it doesn't have anything to do with pushing buttons or resetting- presumably the OP got the regular version uploaded. It's part of our testing process, I'll see if we can simply do something in a different order so it's not there when shipped

Flappy Birds is a fantastic demo.  However, perhaps the code should be modified to keep the brightness the same through out the whole game/ demo.  It really confused me.

It's programmed to do so,

Thanks for the explanation, Ben!
