Alternate Camera apps, but...
I've been testing out several (15 total) camera apps and NONE can handle; indoor, low light, and no flash photos using all default setting like G2 stock camera app. Please test out your favorite camera apps vs G2 in low light conditions and confirm this, but also try out a few awesome camera apps I've been testing out.
1. FOCAL (read on CM controversy and they just fixed FC issues)
2. ProCapture (check out Fibonacci Spiral composition)
3. Camera FV1 ( overrides brightness, huge menu and 5+ second custom exposure and manual focus)
4. Camera Zoom FX (FX)
5. Pudding Camera (full of artistic live filters)
6. Perfectly Clear (after photo fixer)
9. Camera Fun
12. Nemus Camera
13. Paper Camera
14. 4.4 KitKat camera
