64 gig owner that suffered through the auto rotate hooplah....
Despite having made arrangements to, I had never gotten my phone fixed nor exchanged due to my schedule and impromptu trips; however, I updated my phone just yesterday and when i accidentally double clicked the home button, i saw that the camera was oriented in portrait mode. Whoever has suffered with the auto rotate issue will know that the phone is stuck in portrait, except when in the camera/youtube app, for whatever reason. I checked the adminstrative settings (*#0*#) and saw that, despite my screen finally rotating, the X accelerometer was still stuck at an extreme.
This is the only change i have seen, since getting the update. I dont know how, but it seems Sprint might have just beat everyone to it in creating a software solution to hardware problem. Im sure most who had dealt with the auto rotate issue have gotten their handsets replaced by this point, which could explain the 'lack' of noticed bugs being fixed.
Had googled, and there has been no mention of the s6 edge autorotate issue being fixed. First time post, hope this helps. PS there is a slight lag, when it comes to the image rotating, not sure if its always existed.
