I use a Galaxy Tab s2 as my main remote but finding the loading of the discovery section to be very slow. it can take up to 1 min to become useable. On my S6 phone its almost instant as it is on my PC. Is the Tab s2 really that underpowered? They are using the same wireless SSID.
This is not a hardware issue but a performance issue of the Android app (although till now the impression was that the Galaxy Tab S2 was not affected). There is more about it in this thread:
