Samsung is turning out to be the only smartphone brand other than Motorola to update a number of existing devices to Android 5.0 Lollipop. It has already rolled out the sweetest version of Android to the Galaxy Note 4, the Galaxy Note 3, the Galaxy S4, and the Galaxy S5. However, it has reportedly halted the Lollipop update for the Galaxy S4 and the Galaxy S5 in Norway due to a number of bugs.
One of our regular readers from Norway has pointed out that Samsung pulled the initial Lollipop update (which was rolled out in January) for the Galaxy S4 and the Galaxy S5 due to a number of bugs, including the one where Contacts app doesn't work and com.android.phone freezes from time to time. Apparently, Samsung Norway has admitted this on its official Facebook Page, and a lot of users are complaining there about these lingering problems after the update.
Thanks for the tip, Magnus!
