A1 camera is superb in Day light only. It can't beat Google Camera in very low light. Everyone trying Google Camera here for getting Selfie Portrait mods. That not available in A1 camera .. I am not a photographer. But i can tell as a normal user in low light Google Camera perform really better than A1 camera. May be some 3rd party apps can do that but someone loves Google Camera
Low light problem is due to absence of stabilizer hardware. Have you tried HHT mode?
