Since OTA roll-out is carried out on a staged phase, it will take some time to reach all corners. Currently, only 2 percent OnePlus One owners have received the update as of 3:00 am US EDT, 26 August (12:30 pm IST), OnePlus forum member CasperTFG said.
Until then, users can check for OTA update manually by going to Settings >> About phone >> System update>>Check Now.
[Tip: Before checking for update manually, reboot the smartphone.
If patience is not you best suite, you can flash the update directly on to your device as well.
