johnr: What is wrong with 4.4.2 And please also explain why it's also part service provider?
For phones and network connected devices the service providers need to test before updates are released to use their network. This of course will delay releases be it only a small part delay. For non network devices like my Tablet there is no service provider delay, it is purely Samsung slackness.
As for 4.4.2 it is OK but I would like Android L without risking warranty, so official update.
