Ok for music but not to use bluetooth with tablet games nbr + bluetooth conn prob

After rapid receipt of the unit I tested on my tablet Samsung galaxy tab 10.5 S for music no worries by cons, I tested with bluetooth "Real Racing 3" and the sound was shifted and split! Brief impossible to play. I did several test bluetooth and still the same result. By cons with a connection with the supplied cable, no worries. I presume that the Bluetooth connection of the device does not have enough speed to receive information related to the game requiring much material resources.
I also have some problems at the time of connection with my smartphone or tablet, you often turn off and on the enclosure for the connection is done with the phone or delete the device literally bluetooth elements and connecting again.
I am disappointed these problems with the games and connection problems. If I had known, I would not have purchased this device. Fortunately there was a connection jack 3.5.
