I think gcam is doing a great job on Nokia 8 in really low light conditions, but I advise to use the standard camera in other circumstances.
Pictures shot inside, morning light.
One with Gcam (Tolyan's 1.4). On gcam I use HDR+ and manual focus.
And one with the standard camera (no position change!). I use HDR on, manual focus
The second series in the afternoon with filtered (direct) sunlight.
But it is a close call! And perhaps it depends more on taste ...
I think both photographs of the standard camera are 'brighter' and the colours more true to life: wood - statuette - leaves of the orchid
