Please, please, please can we have a simple +/- volume control in the Android app instead of that useless unresponsive slider please? It's bad enough on a 10" tablet .. poke, poke, poke trying to hit the minuscule hotspot and then BOOOM, the volume suddenly quadruples and the neighbours start banging on the walls, but on a small screen smartphone it's even more desperate.

Like others have said, great hardware spoilt by clunky, unresponsive, badly designed software.
