Dimas None from what I can tell.
Still has the same horrible shutter/processing speed where the frame shifts significantly after processing. Unscientific test anybody can do - just take a photo of any moving video or a timer and watch it move. It’s around 0.2 seconds shift.
GCam does not exhibit this issue so it’s just their software - which I suspect will never be improved now the 4a is out and the 3a is the unloved child getting scraps from here on out.
Example - eyes shut in preview, then open…
