incompatible app with some devices while minSdkVersion = 1

Question

I created an app that uses the android-viewflow and it has minSdkVersion="1" , but when I publish it on Google Play I found out that it's incompatible with just these devices

• Samsung Galaxy Mini– GT-S5570
• Samsung Galaxy Pocket– GT-S5302
• Samsung Galaxy Pro– GT-B7510
• Samsung Galaxy– gt-i7500
• Samsung Galaxy Pocket– GT-S5302B
• Samsung Galaxy Fit– GT-S5670

but when I install the APK in one of these phones it works fine, till now I still can't find what did I do wrong to make the app incompatible with those devices.

PS: in my android stats the app works fine with all the platform Version

Compatibility is not only about the minimum SDK version, apparently app (.apk) size and some other things also have to do with it.
