You can try this method

While the Oculus Mobile SDK might eventually spread to other smartphones and accompanying virtual reality hardware, for now it remains relegated to Samsung’s Gear VR. In turn, the Gear VR is designed (both in terms of physical construction and software) to work with only one smartphone from Samsung’s stable of many: the Galaxy Note 4. Obviously, that leaves a large majority of the Android-toting population squarely stuck in their non-virtual realities. What if there was a way to get the Samsung Gear VR to work with other devices?

Inspired by a post by Pure Engineering on Android Forums, we decided to investigate. It turns out using an unsupported phone is not completely out of the realm of possibilities, but it comes with a few major caveats. The Oculus Mobile SDK is currently only optimized for the Galaxy Note 4, its processing suite, and embedded sensors. Using another device will not provide the true Gear VR experience, providing limited control and not taking advantage of the headsets more unique features and software-specific enhancements.

Fitting the phone

First and foremost, the Gear VR is built to connect via Micro USB to the Note 4 and hold it snugly in place with a clamping mechanism. In order to fit another device into the Gear VR, the phone must be generally the same size as Samsung’s phablet, which features a 5.7-inch display.

Any phone should also have a Micro USB connector centered on the bottom of the device. The USB port will strictly be a matter of fit, as the connection will serve no function due to the lack of software link between a device other than the Note 4 and the Gear VR. One benefit of connecting to the USB port is it will help hold a smaller smartphone in place. It is possible to finagle a device without the proper USB port placement into position (especially if it is smaller), but there may be the potential for damage to both your device and the Gear VR headset.

Some devices that we tested and more-or-less fit include:

Samsung Galaxy S5

Samsung Galaxy S4

Nexus 5

Motorola DROID Turbo

In general, if the phone is smaller than the Note 4 it should fit, so you might add devices like the HTC One M8, LG G3, and Moto X to the above list. Most of these devices being too small for the clasping mechanism to function properly, you might utilize a case or get some felt or other soft material for added padding. The Nexus 6 is a bit too large to fit properly, but the OnePlus One slots in without any additional padding.

Once you fit your device, the Gear VR will be used more or less in the same fashion as Google Cardboard or a similar low-cost virtual reality substitute, utilizing the Gear VR’s stereoscopic lenses only.

Installing the right software

Since your unsupported phone will not take advantage of the Gear VR’s special Oculus software, you will need to install the proper applications to create 3D and VR content.

Google Cardboard eye holes

Google Cardboard is perhaps the most full featured of these options, providing stereoscopic viewing experiences to create three-dimensional environments that can be explored with the movement of your head. Google Cardboard includes a number of neat demos as well as the ability to view YouTube in a virtual theater and also import your own content.

Another option would be to use a stereoscopic video viewer like VR Player. VR Player does not include all the bells and whistles that we find in Google Cardboard, but it does offer 2D and 3D video playback tailored to viewing with a set of VR goggles like the Gear VR.

What works, what doesn’t

In the case of using a device other than the Galaxy Note 4, the Gear VR is being utilized for its mounting hardware and lenses alone. As long as your device has a screen similar in size to the Note 4’s 5.7-inch display, you will get pretty accurate 2D and 3D viewing of video, games, and photos. Since the lenses are designed to work most accurately with the Note 4’s display, smaller (and larger, if they will fit) devices may provide a less than perfect experience. The Gear VR’s manual focus wheel can also be used to physically move the display nearer or farther from the eyes to adjust clarity.

The head tracking and VR experience will largely be dependent on the software used. The Oculus technology and software utilized by the Note 4 and Gear VR will not be available, so touchscreen controls (or a Bluetooth controller) are required to navigate menus and perform other actions. The Gear VR’s touchpad, volume controls, and other buttons will not function. You will not have access to the Oculus Store and VR content available exclusively to the Galaxy Note 4 when paired with the Gear VR.

A neat trick, but should you buy the Gear VR for your unsupported smartphone?

It has been demonstrated that the Gear VR can indeed “work” with an Android smartphone other than the Galaxy Note 4, but after evaluating the result we can’t whole heartedly say it’s a very worthwhile experience. Unless you plan on upgrading to the Note 4 in the near future, at $200 the Gear VR is simply too expensive when compared to cheaper Google Cardboard holders that will produce an identical experience.

The real value is in the Oculus software included with the Note 4. It is one of the more refreshing, exciting, and immersive experiences to grace the Android ecosystem in quite some time. Again, that won’t be available on unsupported smartphones, but if you own a Note 4, by all means think about picking up the Gear VR (we’ll have a full review soon).

Please Note: I didn't try in Samsung galaxy P30 but I think this should work.
