App Not Showing Up?

My app isn't showing up on google play store for some phones, like the Samsung GT-S5830i I don't know whether it is because of my or my min SDK or my Screen

Solution 1:

from comment your min-sdk level is 11, that means your app needs minimum of andriod 3.0 (Honeycomb) and the phone you're tested is samsung GT-s5830i which comes with android froyo, (version 2.2) and it's API level is 8, so it wont be displayed in playstore for that device. to support for that phone you have decrement your minimum api level, read about API level and os version from here. and read this link to know more about play store filtering
