How can I find out what radio frequency class my Samsung device falls under?

[AC Question]

Is it class 1, 2 or 3? I have a Samsung Note 4 and, in considering my Bluetooth Device, I want one with a range of more than 33 feet which means that my phone has to be able to support RF Class 1 and I can't find anything in the specs which clarifies this for me.

Cellphone Bluetooth is Class 3. That means about 30 feet clear line of sight. If you put the headset in your left ear and your phone in your right front pants pocket, your body will probably absorb too much signal for it to work. Phone Bluetooth is designed tor "almost touching" devices - if you need more range, get the function you need in a wifi or cellular communications mode. (You have no choice, and you can't make it more powerful - cellphones and the peripherals made to be used with them just are Class 3, and that's all there is to it.)
