its my experience…
android minimum level API setting for Unity <4.0 is android 2.3.3 API 10…
for Unity >4.0 is better minimum setting android 4.0 (ICS) API 14

I am using unity 4.1.2, then if I set API 14, below API 14 level android phone users can’t run my apps?

Yes, it can run but not run good…
because unity >4.0 build .apk take reference from Android 4.0 API 14. .
