After updating my iPhone 6S to iOS 9.3 Safari keeps freezing/crashing more often than not when I click links. I've read online that this is experienced by a lot of people on newer devices, including iPads. My question to those in the software industry is how can this be possible? With Apple's very limited variability in devices running the software how could this not have been picked up in pre-release testing? This is quasi relevant to Tesla seeing how they too keep pushing firmware updates to cars with some variation in hardware but still very controlled.
