This bug was introduced with iOS 7 and remains unresolved. Would someone in the iOS 8 beta please test this for me and let me know if they've fixed it? Hold the phone horizontally the whole time 1) open Safari (or other app which supports landscape). The screen correctly rotates into landscape 2) lock the phone 3) press home then slide to unlock. the screen will quickly rotate counter-clockwise into portrait then immediately back into landscape. Prior to iOS 7, this auto-rotate did not occur when unlocking with the phone held in landscape.
