OnePlus have decided to again delay the cyanogenmode 12S based on Android Lollipop update for the OnePlus Isa. The already overdue update was scheduled for release this week, but has now been delayed for another week
This means that the update should be rolled out starting from the 27 Abril 2015.
The reason for the delay is that the update will now include the ‘OK OnePlus’ feature. The download version should be released first and then the eagerly awaited OTA rollout should start, provided that further delays are not announced.
OnePlus One owners who have already installed the update, will have to again update the phone to receive the ‘OK OnePlus’ feature.
