Part 2 > Q95: Group Play Connection Problem (1/3)
Q : I've tried to connect to the Galaxy S4 and Galaxy Note2 via the "Group Play" app,
but the connection was not established. What should I do?
A : Sorry for your inconvenience.
"Group Play" in the Galaxy S4 works based on different connection technology from the existing platform on the Note 2.
So "Group Play" in Galaxy S4 is not compatible with other existing models and can be only connected between Galaxy S4's.
Please refer the next page that explains the difference of the connection method with each model.
