Hi. I am following the Fairphone project for a while. They look for a modular point of view for smartphones, which includes the possibility to upgrade the camera. Since they upgrade the camera every a few time, and they also are thinking in a new smartphone model, I was thinking in wich would be the best option for them to have the best open source camera performance. Which would be the best camera sensor/lens/..., or the best combination of SoC and Camera sensor/lens/.. to make lcamera to work the best?

The last camera upgrade from them it has been this:
Rear camera: 12MP CMOS sensor with dual flash (Omnivision OV12870 – BSI)
Front camera: 5MP CMOS sensor (Omnivision OV5670)

Since they are constantly in touch with their community and take their opinion in consideration, besides that they are triying to give a good open source experience, what would be a next good upgrade from an lcamera point of view?

Most of the time having a better hardware but with less software optimization is worst than having a less advanced hardware but greatly optimized. This is why I am curious about this question and I think lcamera could be of greeat help to improve the fairphone camera performance.
