How to Update OnePlus One to Cyanogen OS 12 build YNG1TAS2I3
The OnePlus One users can now download a new Cyanogen OS 12 build version YNG1TAS2I3. The update brings the necessary bug-fixes for a number of issues that smartphone owners have been facing for a while. These include touchscreen sensitivity, Bluetooth connectivity with several in-car systems and MMS text sending on various carriers.
OnePlus has previously rolled out a couple of OTA updates to fix the touch unresponsiveness issue, but it had only got it fixed partially. The manufacturer now claims to have resolved almost all the nagging common problems with the OnePlus One, thanks to this new Cyanogen OS update.
It’s worth mentioning that the latest build of Cyanogen OS 12 is based on Android 5.0.2 Lollipop, and not Android 5.1.1 — an update OnePlus recently promised.
The YNG1TASI3 update comprises of both OTA (just 20 MB!) and full ROM (566 MB). Those who are running an earlier Lollipop build YNG1TAS17L are recommended to use the smaller incremental OTA zip file, which should save more than 500MB storage space on your phone.
Nevertheless, if the OTA update fails to fix the issue, then you could flash the FULL version ROM.
