Android app not compatible with ASUS NEXUS 7

Question

I received a feedback for a published app from a user with a Asus Nexus 7 tablet: Google Play Store says the app is not compatible with the device.

I can't figure out why, I believe the Nexus 7 has everything the app needs, but I'm obviously missing something.

Here is the relevant manifest snippet:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="xxx.xxxxxxxxx.xxxxxxxxxx"
    android:versionCode="3"
    android:versionName="2.1" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="18" />

    <uses-feature
        android:glEsVersion="0x00020000"
        android:required="true" />
    <uses-feature
        android:name="android.hardware.location"
        android:required="true" />
    <uses-feature
        android:name="android.hardware.location.gps"
        android:required="false" />

    <uses-permission android:name="android.permission.WAKE_LOCK" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
    <uses-permission android:name="android.permission.VIBRATE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
    <uses-permission android:name="android.permission.CALL_PHONE" />

Answer 1

Its because of this permission ---

uses-permission

`android:name="android.permission.CALL_PHONE"

your app user must be having asus nexus 7 Wi-fi only model.
