I have a few issues so far. Battery life is stable and the build is pretty awesome!
1.) This is probably only relevant to me/a few. But I play 'Summoners War' in my spare time, and it crashes on this build. If I want to play the game, I need to delete and reinstall. Then, I can play it once, but once I close it, if I open again it will crash. *This could also be a problem with summoners war, I hear it has issues even on iOS8, but is probably worse for me using the iOS9 beta.
2.) Photos/Camera. Not a big deal, just a small glitch. But it seems when I take a photo in landscape mode, it saves it in portrait mode (upside down) when I try and look at my photos straight from the camera app. When I go into the photos app though, the picture is the right orientation. Again, a small glitch, doesn't really affect anything.
3.) Also something small. but Siri Suggestions seems to overflow into the 3rd row, but barely. A picture is worth a thousand words here:
