Interesting. LGcamera.apk is not in the Optimus T roms. The camera is called CameraApp.apk. Did you mean to say that, or do you think I should find lgcamera.apk to download from somewhere?
Also, I realized that Optimus U appears to have exactly the same hardware style as the S, and read a review that it provides robust camera control, including exposure. Possibly also true for Optimus V. Do you know where I could get ahold of roms for either of those two? Google isn't turning up much.
Thanks!
Tried to replace all camera-related libs and the app. It booted but then all apps that tried to use the camera crashed. Found this for the V. [ROM] ║ RodimusROM v1.0 ║ [2/2] Optimus V A diff between its and lego-rom's lib directories show that not too many files are different. Among the different are libcamera and liboemcamera - not the other camera ones. Restarted with them and the camera loads, but no exposure control. Alas. I wonder if other differing ones matter - like libmmjpeg is different and I wonder if it may have something to do with the camera.
Also, the app Z-DeviceTest shows this info about the camera:
Exposure compensation: 0
Exposure compensation step: 0.1666667
Min exposure compensation: -12
Max exposure compensation: 12
