U.S Cellular has officially released Android 5.1.1 Lollipop for users of the Samsung Galaxy S6 and Galaxy S6 Edge on its network. With T-Mobile having already released the update for the smartphones on its network, Verizon, Sprint and AT&T are next in line.

Just this April, Samsung introduced its latest flagship smartphones, the Galaxy S6 and Galaxy S6 Edge. The phones represented a change in style and design for the company's flagships, which many felt was a nod to the latest Apple iPhones which, not coincidentally, offered Samsung's new handsets its biggest competition.

Both the Galaxy S6 and Galaxy S6 Edge came running Android 5.0 Lollipop out of the box and were the first Samsung handsets to do so. It's no surprise that as soon as Google introduced the next upgrade of its operating system, the latest Samsung smartphone duo was set to be the first of the company's devices to receive it. Indeed, the international rollout of Android 5.1.1 Lollipop to the devices has already begun, and last week, T-Mobile became the first U.S. carrier to release the Android 5.1.1 Lollipop update for the Galaxy S6 and Galaxy S6 Edge.

Now, a second U.S. carrier, U.S. Cellular, has also joined the mix, and an OTA update is currently rolling out for users of both devices on the network. U.S. Cellular is the nation's fifth-largest carrier, with around three million subscribers, and it has traditionally been late to the party when it comes to Android OS updates, so this move is something of a surprise as the big three — Verizon AT&T, and Sprint — have not released the update for users of the phones on their networks as of yet.

U.S. Cellular customers can upgrade their Samsung Galaxy S6 and S6 Edge either via Wi-Fi directly from their phones or via Samsung Kies using a computer and attaching their phone with a USB cable. While the company has not released an official change log for the update, it is expected to bring various bug fixes and performance enhancements, potentially including the guest mode and camera tweaks that came with the T-Mobile Android 5.1.1 Lollipop update.

The release of the update by T-Mobile and U.S. Cellular should bring additional pressure on big three carriers Verizon, AT&T and Sprint to release the Android 5.1.1 Lollipop update soon for the Galaxy S6 and S6 Edge on their networks, as understandably, impatient users of the phones on those carriers are certain to vent frustration at the smaller networks beating them to the punch. We'll be sure to keep you informed as soon as any developments break in the upcoming release of the Android 5.1.1 Lollipop updates for the Galaxy S6 and Galaxy S6 Edge on Verizon, AT&T and Sprint.
