If I'm not mistaken if you flash a slim or minimal gapps package you should only get the aosp camera. A lot of the gapps packages have the Google camera as part of the package and it overrides the stock camera app. Also, I told you the wrong lenovo camera to flash I think. It should be the one with permissions to flash to get it working. It worked great for the family trip to the zoo yesterday. Hope this helps.
