in just a few minutes, I can confirm Autostart works, but the player still takes from 7 to 10 minutes to connect to wifi solidly without dropping, but signageplayer did infact start exactly as it should. the Hide Bottom Bar app works perfectly, but not automatically, I have to start it each time.
overall, if this unit continues to work even this well, I will be satisfied.
Just to be clear, I have disabled all automatic updates, and several apps like Facebook, Gmail, Youtube and others so I don't receive any popup notifications on the device and I am using an HTC 5v @ 1 amp Mini USB charger cord to power the MK808 instead of the supplied power adapter or the OTG port. I had the charger here from an HTC Tmobile Sensation 4G smartphone, and I had read the some people were having better luck using it than the supplied adapter. I am on a different forum looking at flashing a different rom image, but it seems that some people are having difficulty using it and I don't want to screw anything up at the moment, or at least until the stock rom becomes a problem. I will report any issues if they show up.
