Samsung has just unleashed an upgrade for the Galaxy Note 3 that makes it even more like the Galaxy S5 than previously.

According to tech news websites PhoneArena and GSM Arena, Samsung Galaxy Note 3 owners in the UK have claimed they are starting to receive a firmware update that brings a few features previously only found on Samsung's Galaxy S5 flagship smartphone. The update is limited to the Snapdragon 800 version in select markets, such as the UK, and it is rolling out gradually.

The first new feature is Knox 2.0, a secure mobile platform for enterprises. Samsung made Knox to enhance security on devices, from the kernel to apps. The platform therefore allows companies to implement a bring-your-own-device program. In other words, your Galaxy Note 3 will soon be secure enough for both work and personal purposes.

The second feature is Download Boosters, a setup that allows you to download files much faster. It combines your 4G LTE cellular connection with any available Wi-Fi connection to maximise download speeds. You will therefore be able to download large files in a jiffy. Just watch your data use, because we assume this feature can also be taxing on your plan.

Samsung's Galaxy Note 3 is an Android phablet that released last September. It reportedly sold more than 10 million units within the first two months of launch. Notable features include a 5.7-inch 1080p Super AMOLED display, 13MP rear-facing camera, plastic leather rear cover with faux stitching, and multitasking-oriented software, among other things.

The new Galaxy Note 3 firmware weighs about 185MB. If you are lucky enough to receive this update, which as we mentioned largely improves download speeds and overall device security, expect it to be delivered over the air.
