iOS 10.1.1 iPhone 6s+ Ever since the first public release of iOS 10, Safari has been slow for me, and worse: if I switch tabs or switch apps momentarily, Safari goes all white and is apparently frozen or dead. Only swiping it away in the app switcher, and relaunching, will fix it. And it's a fairly unpredictable bug, I don't know exactly what triggers it, although I see it about twice a day at least. I never have more than two tabs open, so it's not some ram issue. Honestly I am not a Chrome fan, but after three iOS updates and Apple still hasn't fixed this, I couldn't take it anymore. Chrome has been fast and stable, which absolutely wasn't the case back in the earlier iOS 9 days.
