the projector and the camera do not focus, is it possible to manually adjust the focus of the projector? since automatic does not work, in addition it has a line that flashes during the projection along the low side. In addition, to try to solve the problem, I deleted and formatted my blackview max 1 and lost the nvram, how can I recover it? and what does it contain? do you have any information about the projector?

kindly make available the full android 8.1 rom i can't find it anywhere.

You can try to recover your phone to factory setting.
If no work, you'd better contact your seller or our professional after-sales directly. The phone need repair.
