My Android App doesn't list on Google play store on some Samsung Phones? -

i have read through other questions on published app not showing in results on phones. none has helped solve peculiar case.

my manifest has:

<uses-permission android:name="android.permission.internet"/> <uses-sdk android:minsdkversion="19" android:targetsdkversion="19"/> 

problem: app doesn't show in google pay store search results on samsung note-2 & note-3 shows on samsung note-4 (strange!!). app lists in search on other phones like: lg, htc etc in google play store.

q. minsdkversion/targetsdkversion matter?

thanks

i don't know version phone's have example if minsdkversion 19 isn't going work on phones below api version 19 note 2/3.
