Ordered two A3's off Amazon. One works great, the other my father just opened today as a gift and it doesn't work at all. I plugged the tiny USB receiver into my box, nothing. Have double checked the batteries, nothing. Red light on remote will flicker occasionally, but the only thing you can do is turn our Minix Neo boxes on/off. I checked this on two Nimix boxes I have. Both the same model. As soon as I plug my original A3 remote/USB receiver into the boxes, it works great again. I've been using this one all week and love it. I submitted a request for a shipping label which will be going out on Monday morning. Was hoping to maybe get some last minute troubleshooting. It sure seems like it's DOA. I was able to briefly get it somewhat working, in that the arrow buttons would function, but it was EXTREMELY laggy. Then I tried using the AirMouse, and that too was so laggy that it wasn't useable. Then after 20-30 seconds it just went off completely. The strange thing is, you can turn the Nimix boxes on/off successfully every time, but none of the functions work. Can't figure this out. Assuming it's just a lemon, and will be ordering a new one. Any advice before I do that? Thanks!
