And ring goes on but the screen is off and I have to struggle by pressing power button several times to turn screen on still it does not work. @OnePlus you have to do something. Though I'm grateful of you guys that you give updates to this old devices. Kudos to the team. Hoping for the quick solution. P. S. Check the image for build info.
