If you are looking to jump on the “must have the latest phone” train, then you may be looking at the Galaxy S9 or S9+ from Samsung. However, if you are also a VR fan, then you’d better make sure the VR headset fits your shiny new S9 device.
The Galaxy S9 did not come with new VR hardware. However, they do work in existing Gear VR headsets. But which one? The S8 version will no longer work with the S9; you will need the Note 8 model to enjoy VR on your S9 device. According to Samsung, the S8 model might damage your S9 device. The Gear VR model you are looking for is the SM-R325 model.
With the new and improved Snapdragon 845 processor in the S9 which includes improvements for VR and AR, you can look forward to improvements.
