Use Third Party Brightness App
If you are still not satisfied with the brightness adjustments provided in you stock LG V30 Plus, you can install a third party app to control it for you, such as Lux Auto Brightness.

It could be that when you first uploaded your fingerprint to the device, that it did not read correctly. Try deleting your old fingerprints that are not working and re-uploading them to the device.
