Slow on iOS8
The reason why I bought iPhone 5s is to be able to use Instabeauty which is one of the best photo apps I have encountered so far. However when I upgraded my iOS to iOS8, I noticed a slow execution when I press the click button or any area of the photo for capturing. It would seem its not capturing but after a few seconds it will show a captured frame. Theres a noticeable inconvenient latency. I wish Instabeauty Team will upgrade their software pack to keep up with iOS8. More power.
