hello, i have both the gear vr, and a galaxy a50. ive messaged samsung/called them, etc, and they all say it is mot supported. however, the a50 does sort of fit in the gear vr, the connector i have is a little rounded, so it doesnt entirely fit in all the way down. the mouse pad on the gear itself does actually function for me, and so does motion tracking. i did also manage to sideload an apk for the occulus store after some digging. most apps/games do work with a regular gamepad. i have issues with minecraft for the gear showing dounle vision. also, anytime i try to connect the gear vr controller included with the headset, the app crashes. so, it does KIND OF work. you can force it to. its not optimal, however.
