http://forum.xda-developers.com – Is there something wrong with the Bluetooth feature on Jellybean 4.1 or the with the Nexus 7 itself? I bought a Bluetooth Keyboard for it for about $30. When it's working it works great, but it just randomly drops out when I am in the middle of typing. If I press the button to the right then they will connect to each other again, but then it drops out again in a few minutes. It's pretty much a useless device, because I can't keep constantly pressing the button while I am typing, it slows me down dramatically. Does anyone know of any specific problems with Bluetooth on the Nexus 7 or with (HowTos)
