Bluetooth keyboard performance

I noticed today that there’s a huge difference in bluetooth keyboard performance between my old iPad 3 and my new iPhone 6 Plus. My new iPhone is much more responsive than my old iPad. In fact, bt keyboard in VividTracker is almost useless on my iPad. The latency time is horrible and it sometimes even drops keypresses if I press too quickly. Perhaps there’s some optimisations that can be done in the actual code, but I doubt it. You hopefully have a newer iOS device than my old iPad, which means this may not be a problem for you. However, I just want everyone to be aware of this.
