I bought the 5S and I find it extremely laggy on almost all situations.... I guess it's time to turn off all the "features" that comes with it, like transparency.... Find it hard to believe that Apple would release such a bug ridden or laggy iOS. I would expect this on older devices, but their flagship? NO! I was using Harry's laptimer and after a couple of video processing, the phone appeared out of ram or something because the WHOLE UI got laggy. Thoughts?
