Yes i have root.
Video i followed HERE
Just out of curiosity i went ahead and tried the Lg G3 camera tweak to test out the fps improvement. I follow all directions given and was left with a broken camera app. So using my past experiences with the S3 (lol) i downloaded titanium backup and backed up my camera app before i even attempted. After i finished with the tweak i ran the app and it was unresponsive so i undid the steps and restored the camera app with tb. The application now works however i dont get to use the entire screen as seen in the screenshots, also i can no longer record with the camera app. Any help would be much appreciated.
