There are many owners of the Samsung Galaxy S6 and other Android handsets that don’t have any idea as to what version of Android they have on their device. Some owners do know and they do update when they are told they can update. Others constantly check to find the latest update as soon as they can and go ahead and make the update.
Those with the Samsung Galaxy S6 waited a long time to get the update to Android Lollipop and they could only watch as owners of devices including the LG G4 got updated.
Samsung at one time offered up pure Android by way of the Google Play Editions but these have dropped off as they haven’t been as popular as you might have thought. Instead of offering up pure Android, Samsung now offers the Good Lock app. However fans of the pure experience haven’t been happy.
Marshmallow did arrive for the Samsung Galaxy S6 but people missed pure Android as updates do seem to come faster. We haven’t seen the Google Play Editions for over two years now but if you are missing it you might want to bear in mind that support is typically bad and this is something that Sony found out.
