In the end though, this is all that owners of the Galaxy S4 have available if they want to get the latest version of the operating system on their devices, as currently the S4 is being updated to Android 5.0 but we don’t know if there are any plans to push it even further than that.
There is actually an option to prevent the update from being deployed to a user’s device, so it’s probably not that well optimized for everyone, at least in its default state. This makes it important for users of the Galaxy S4 to look into custom ROM options if they want to have the best performance possible.
This is another common issue with Android – sometimes, even the official releases of new versions don’t work that well with all devices they have supposedly been certified for, and this makes it important for users to be careful and always be on the lookout for information about how well the new OS versions will work with their own devices.
That’s also why custom ROMs are so popular among Android users, as they allow them to experience features that may never arrive to their devices in any other way, which is one of the benefits of using a more open operating system like Android.
