your manifest has

<uses-permission android:name="android.permission.read_phone_state"> 

that permission automatically assumes use android.hardware.telephony feature (as phones have read_phone_state). per optimizing android 3.0/tablets document, application show incompatible if have android.hardware.telephony feature required. add line

<uses-feature android:name="android.hardware.telephony" android:required="false" /> 

to ensure devices without telephony still show compatible. make sure application handles devices without telephony (as attempting read phone state crash devices).
