Getting a Samsung Android device means that you’ll be surrounded with numerous custom ROM’s to customize the device or regular official updates from Samsung itself, sometimes these updates are either delayed or in some cases are region specific, there are also instances that device updates are already available but delayed because the device that users have is carrier locked or users just needed to reflash the device for some reasons. Whatever the case maybe, users could either wait for the update to be available via Over-The-Air (OTA) or manually install the update themselves through a special application on the PC via Odin or other similar software.
