I installed iOS 8 OTA with no issues, and I liked what I saw. Everything seemed to work well at first. Later discovered that my car audio system would no longer read my (tagged) iTunes library. Bluetooth became buggy. Everything had always worked perfectly with iOS 7.x.x. Also, later discovered that the iPhone Settings App would crash when trying to Manage Storage. [personal note: imho; The settings app should NEVER crash, for any reason]. Fortunately, I was able to downgrade back to iOS 7.1.2 while Apple was still signing. Restored as new, and re-setup everything as it was before (but better

) using iClould & iTunes. I'm going to miss voice text messaging, and whatever else, I don't know.
Am looking forward to my future iOS 8.x.x upgrade. This will happen when I'm assured that the (2013) car player works without issue (will check this in the user forums). I think I can wait until iOS 8.1, whenever that may be. Until then... I'm continuing to enjoy and appreciate my perfectly working without any issue, iPhone 5S rocking iOS 7.1.2 Color me happy, with (probably) an iPhone 6S in my future. -Rob
