Greetings, I've been living with iOS 7.1.2 on my 5s for these many years, but I'm finding more and more things to be incompatible. And I realize that this Wednesday, will bring an end to iOS 9. For those with 5s' how do you find the tail end of iOS 9 treating you? Will I want to smash my phone against the wall if I upgrade? I can handle a couple dropped frames here and there, as I navigate the phone. And I fully expect EVERY app to take a fraction of a second longer to launch(yes, 7/2 is a fraction also). Other than these, anything else I would need to worry about in "upgrading" from iOS7 to iOS9? Thanks! PS - Yes, I'll be backing up my phone before doing this.
