Hi, I have an S7 with Tmobile and when I first used the Gear VR it worked perfectly. Then I tried projecting it on the television and couldn't do it. So I read on the message boards to get into the Developer Options in the settings and change the settings 720x 1040. It worked but caused major major juddering/stuttering. I turned off Developer Options. It still juddered big time. Then I factor rest the phone. Still major juddering. No matter what I do with the phone (uninstall apps, uninstall Oculus, reset the phone) major juddering. It judders so bad I can't even use my VR for more than a minute before I get a splitting headache. Please somebody help because I was really enjoying the VR for those couple of weeks!
