I have a S900 Pro box (generation 3) and the box is having a problem. The remote control arrows and OK button do not work the way they are supposed to. The arrows seem like they are representing letters (when I do a searh for apps), rather than moving the cursor. I bought a brand new remote control and having the same problem. I also tried putting new batteries in it. Same problem. So I'm guessing there is something wrong with the box? Any suggestions on how to fix it? Thank you in advance.
