OnePlus has officially released its OxygenOS to their OnePlus One phones, which were dubbed at the time of launch the “flagship killer.” While the popularity of the OnePlus One devices has been mixed, especially in the United States, the overall mission of OnePlus has been something that users have gotten behind entirely.

OxygenOS is aimed for OnePlus One smartphones and based on Android 5.0.2 Lollipop. Carl Pei, the co-founder of OnePlus said, “We want to be careful that we aren’t adding features simply for the sake of differentiation,” in an official blog post by the company.

At this point, for OnePlus it’s about delivering a product that can really stand the test of time and won’t just be a fad. To this point, their OnePlus One devices have performed very well – with impressive specifications – and availability for LTE, it has made OnePlus One device an interesting alternative to the traditional Android and iOS options.

He pointed out that while many companies are worried about creating custom ROM’s, OnePlus has very simple goals. He added, “We place things like performance and battery life over gimmicks and bloated features.” However, what many individuals are talking about now is the strained relationship between Cyanogen and OnePlus. Previously, Cyanogen was the operating system of choice for OnePlus One smartphones but given the animosity in their relationship over the course of the last few months – it became necessity for OnePlus to create their own operating system.

Some concern though has been raised in the way that users are forced to go through the update process to OxygenOS. Some reservations have been made over the fact that a complete wipe of the system is required, in order to actually install the update. The process is known as “flashing,” and there are risks associated with it – but at the end of the day this really is a matter of following the instructions that the company has issued to this point. There are also a lot of tutorials available on YouTube and other video networks, for those who are looking for a simple solution to the update. Even better is that OnePlus is actively working on pursuing a quicker method for administering the update and future updates alike.
