Hi Max-ML,I am with trCamera v7 Xmas edition since Xmas and it works fine.
Nikita mods are stable as well. Both support 2nd lens.
As for v8 most of them don't work as missing lots of settings inc crucial one - disable hexagon.
GC 8 mods with hexagon on/off option work but not perfect at all.
Parrot works but I suggest 8.1.011_Aspen... (al_ro aka marlin_ku)
You can keep GC7 as well.
Not perfect anyways.
If you use parrot -you should clone it otherwise it updates GC7 and that's no cool as GC7(tigr or nikita) is stable.
I tried your suggested Big file Gcam Aspen mode and the picture quality is very good (in the same level of Nikita I guess). It looks more warm in terms of color, not so blue/rose as nikita photo, also the front camera as better colors (for my taste)
The only problem is the slowmotion mode, can't make it work... it crashes all the time.
Did you manage to work?
Thanks in advance
PS: I tried also Parrot 8.1 version but has worst quality picture, so I exclude as option..
