To mark the anniversary of its first device, Indian manufacturer OnePlus has said the OnePlus One smartphone can now be bought by anyone, rather than only those with an invite, as it “opens up sales globally”.

However, the company will stick to the invite-only strategy when it releases the OnePlus 2.

“We have always wanted to put great products into the hands of more people. And, we now feel confident that we have matured enough to handle the increased complexity that comes along with opening up sales completely,” the company explained in a blog post.

The post also noted that the company has sold over one million phones and expanded to around 700 employees.

Speaking about the OnePlus 2, the company said the reason for the invite-only strategy is to manage the risk that comes with a new product and which is increased as part of its commitment to “maintaining razor-thin margins in order to give as much value as possible back to our users.”

Earlier this month, OnePlus announced the release of its OxygenOS platform, which it said is intended to provide “faster, more meaningful updates and a better-integrated range of services for every OnePlus user”.

In December, a bar was put on sales of the OnePlus One in India, as part of an ongoing spat over the use of the Cyanogenmod platform in the country, and following a complaint from local rival Micromax.
