How about creating fans for cooling in the new Gear VR for Samsung phones. The small fans can cool the phones and keep the users engaged longer.. Add fans at the bottom, sides or top. User should be able to plug in to the charger port and start the fan at the same time. That is free..
The is not the problem of the Gear VR, but the overheating of the Samsung s6 or s7 , the VR mode used more power. I used a pillow and keep the VR cool. Any fan would do it.
I have the Note 4 version of GearVR. I solved the overheating issues with a 3D printed face plate, small computer case fan and a battery pack that I attach to the top strap with velcro. You can use the 3D Hubs site to find someone near you to print the face plate. I have had zero issues with overheating since I got this.
I have an S7 Edge. i am only able to use the VR for about 25 minutes before getting a notification saying the phone needs to cool down before continuing. I have made sure all other programs are closed before using but I am still having the same issue.
