Then you would likely need to wait until iOS 10.2.x or even later versions. iOS 9.3.3 is approaching its end of support time so no wonder why it is more stable than a system at its starting stage of support time.I just hope the next beta is as stable as the 9.3.3 betas, the 9.3.3 betas are super stable and b5 is basically good to go as the final build in my opinion. Can't wait to jump back in the iOS 10 betas once it's more stable!
