Apart from Samsung, LG is one of the very few smartphone makers to continue and offer stylus-enabled handset on a yearly basis. The so-called LG G4 Stylus was launched internationally in May 2015, right around the time the device was heading towards the US market under the name of LG G Stylo. Although it was released with Android 5.0 Lollipop out of the box, Sprint's LG G Stylo has been updated to Android 6.0 Marshmallow in late December 2015. Now, roughly three months after the aforementioned events took place, T-Mobile's LG G Stylo joins the Marshmallow family as well.
As is usually the case with over-the-air (OTA) software releases, owners of the LG G Stylo and T-Mobile US customers will be prompted to update their smartphone's OS at any point throughout these next couple of weeks (March 7 - March 21). The update's availability expands gradually, which means not every LG G Stylo will receive the OTA notification at the same time. Alternatively, owners of the device eager to upgrade the OS to the latest version can trigger the update manually by heading down to the "Settings" menu, and digging further into "About phone" > "Update center" > "System Update". The Android 6.0 Marshmallow update for the LG G Stylo bumps the software version to "H63120b", and weighs roughly 767 MB so it's recommended to use a Wi-Fi network throughout the whole process.
As for the changes included within the update, Android 6.0 Marshmallow promises improved battery life through a new power management system called Doze, which can be summarized as a new set of rules designed to determine when the phone should enter sleep mode. Another exciting part of the Marshmallow update is Google Now on Tap - a major extension of Google Now which allows users to summon the digital assistant on any screen.
It's worth noting that T-Mobile's update arrives right around the time the LG Stylus 2 is beginning to make its way on shelves, at least in South Korea where the sequel is now available for $328. The Stylus 2 features a similar 5.7-inch display with a resolution of 1280 x 720, and unsurprisingly, it runs Android 6.0 Marshmallow out of the box.
