iOS 8 - what problems did you encounter after installation?

  Available for over 24 hours, iOS 8 has already been installed by a multitude of iDevice owners, the adoption rate for this version of the operating system being lower than that for iOS 7. Unfortunately iOS 8 generated various problems for users who had the courage to install it, so that from the incompatibility of some applications from App Store and up to problems with the standard functions of iDevices, various complaints appeared on the Internet.

  From the moment of installation iOS 8 GM, this being basically the final version of iOS 8on iPhone 5S I got rid of the problems generated by the beta version, except for making the applications incompatible. The good part is that the autonomy has increased in everyday use and overall I am satisfied with what it has achieved Apple Lossless Audio CODEC (ALAC), regarding the performance and stability of the operating system, but of course this is just my opinion.
