OnePlus will complete 15 percent of the overall rollout today for Cyanogen's much-anticipated Lollipop OS version, the CyanogenMod 12S.

While fans are running out of patience to experience the software update for their OnePlus One phones, the Chinese smartphone manufacturer assures fans via a Twitter post that the last 10 percent of the rollout will be completed tomorrow as the 75 percent has been done yesterday. However, the team has not announced which regions will get the update first and next.

OnePlus' Carl Pei tweet: "We've learned it's irresponsible to give ETA's when we're not sure. Let's do probabilities (rollout start): today 75%, Tue 15%, Wed 10%."

As the company announced the update will be coming in a few days, some tweet responses on the post proposed India will first get a taste of the update. In a previous post, Pei already said: "Calm down everyone, it's coming very Soon^TM. We underdelivered, but getting asked same Qs hundreds of times/day is not very productive."

According to reports, CyanogenMod 12S will bring improvements on privacy and permission controls. The new Live Display feature will the go-to menu option for bring into line the display according to user's personal options.

Just last Friday, the Chines smartphone manufacturer revealed that CyanogenMod 12S ROM has been approved by Google, which caused delays due to certification issues. It was slated to release on March 30, but to no avail. Instead, OnePlus has released another alternative Android software called OxygenOS. The alternative software has features that Google's Android Lollipop does not have.

OxygenOS has a lock screen featuring Lollipop notifications without compromising the music playback user interface. The notification bar can be rolled to the left and right sides to access notifications and quick settings without disturbing the Lollipop bar format. While Cyanogen's home screen and drawer settings are placed in a third drawer without disturbing the default Lollipop user interface.
