Same issue with Open Camera. With Camera FV5 also, although I'm able to take sharp picture with the manual focus.

This is not a sollution, the problem is not the application, is the driver itself. Hoping for a firmware update that works.

Hello! I have a problem with the rearview camera on Blackview P2 Lite, the camera is very blurry in the corners, and the photos are blurry, third-party applications do not help where can I order a new camera for blackview p2 lite?

well it is a problem with the app and how its communicating with the sensor, im using the 0718 update on my bv8000pro and it has improved the camera significantly, did you do a "clean" flash or a "dirty" flash?

There really seems to be an issue with the camera focus. I've opened a dispute with "Blackview Official Store" on Aliexpress because of it, but the people responding there don't seem to take the matter seriously.

Your application seems to do some kind of unsharp masking (USM, https://en.wikipedia.org/wiki/Unsharp_masking) to "enhance" the image, instead of fixing the focus issue.

This has the effect of adding a lot of noise to the picture (especially visible on low light conditions) and doesn't fix the focus issue. I'd be glad to help fix the issue, but without the code it's hard to do ;-)

Here's an example of a picture (it works worse with focus at infinity):

Here's an experiment made with a black-white pattern, which shows both that it's not in focus, and that the software uses USM on it:

Only thing I'm not satisfy is the quality of the camera. It is not 16mp. Just like an VGA camera. Black view should post a proper solution for this. My previous xiaomi 3s camera gives much better quality of pics.
Please do something for this issue or we all will open a dispute regarding this.
