iOS 10 painfully slow on iphone 6

Its been a few days since i installed iOS 10 on my 64GB iphone 6 and its just so slow to the point that its becoming useless! What the point of using a smart phone if the camera takes 3 seconds to launch and you have to tap a contact three times for the phone app to start dialing! I have tried turning off background app refresh and limiting graphical computations but no luck.
