OnePlus may have already announced its smartphone offering for this year, but many people are sticking with last year's One. And this news is for them. The Chinese startup's first handset is now finally being updated to Android 5.1.1 Lollipop, which is the base for Cyanogen OS 12.1. This is now rolling out to OnePlus One devices worldwide, though in a staged fashion - which means it may take a while for your phone to notify you about the update. If you're impatient, however, you can go to the Source link below and download the update - either as a full ROM, or just as an incremental jump from the last Cyanogen OS 12.0 release based on Android 5.0.2 Lollipop. The new software comes with everything that Google has included in Android 5.1.1 (mostly bug fixes), but also some Cyanogen-specific things. First off, you'll find out that your Chrome homepage has been changed to Bing. Thankfully though, you can easily get rid of Microsoft's search engine by using Chrome settings. Next up is a new Phone app, one that features integration with TrueCaller, a service that lets you identify who's calling even if you don't have that number in your phone book. The design is a little different too. Finally, the built-in launcher has received a new option for the app drawer, namely showing it as a vertically-scrolling list (and this is the new default). If you don't like the Android Marshmallow-like feature, you can switch back to the paged drawer from the launcher's settings menu. UPDATE: The rollout has been stopped, the new software has been pulled by Cyanogen without an explanation as to why. Only 2% of the OnePlus One units out there actually managed to get it. Clearly, some issues were spotted, but what those are is a mystery. Hopefully they will get fixed soon so the rollout can...
