Samsung's latest smartphone, the Galaxy S4, is slowly reaching its customers and much to the surprise of everyone, the devices on the Sprint network have started getting the first software update.

The software update is being rolled out to the devices over the air (OTA) and is expected to fix some performance-related issues.

According to Android Police, the update is 30MB in size and has the build number L720VPUAMDL.

As the update has been pushed now, people will get the update messages as soon as they turn on their Galaxy S4 devices after unboxing. Sprint and Samsung have not issued any statements so far about the update, but the message received on the devices shows that the update is going to fix some bugs and improve the performance of the device.

This is not the first time Samsung has pushed a software update as soon as it released its smartphone. At the time of the Galaxy S3 release, some of the devices got the update only days after the release.

Samsung Galaxy S4 devices are reportedly facing some UI-related issues, as the user interface seems to be very slow when the user is involved in multitasking.

The update is not an Android update and it is just related to the devices running on the Sprint network.

Sprint released a software update for Galaxy S3 devices last week, but kept away from rolling out the Android 4.1.2 Jelly Bean update for last year's most-sold smartphone.

The update version L710VPBMD4 fixes the Homescreen bug in the Galaxy S3 devices and at the same time it comes with the Multi-View feature.

With the help of the Multi-View feature, a user can run two different applications at the same time, keeping both of them visible on a split screen. The feature helps users who always want to multitask with their smartphones.

Receiving a software update is always good news for the owners of smartphones, but when the update is rolled out just after the launch of the device, it can send a wrong message to the market.

As everyone, naturally, wants to buy the best product on the market and expects the product to be perfect, this kind of update shows that the device's factory settings were not perfect, thus the release of an update.
