Galaxy Note 9 owners have run into an issue while trying to use the latest Samsung Gear VR headset. The main problem is due to the actual size of the phone. It's larger than the previous Note 8. White Samsung is not releasing a new Note 9 compatible headset at the moment, they have offered to send Note 9 owners a free adapter to make the current gen headset work.
"The Note9 is compatible with your existing Gear VR, but a new Type-C adapter is required," Samsung states in its troubleshooting guide. "Current owners of the Gear VR with Controller (model SM-R325) can obtain the new adapter at no cost by contacting 1-800-Samsung."
