Android App: My Manifest accepts all screen sizes but the Samsung GT-S6500D can't install it

Question

I have an app in the Google Play Store. I have set up the manifest so that for screen sizes it accepts small, medium, large, and extra large (all of the screen sizes). The app is install-able on everything I've come across for both phones and tablets, EXCEPT now someone has mentioned that their Samsung mini 2 (Samsung GT-S6500D) doesn't let them install it. It tells them that the app is not compatible with their device.

I've already verified they are running Android 2.3.6, and my app works for anyone with 2.3.3 or below.

I've also been told the Samsung Galaxy Tab 2 says it is not compatible. Why is this happening??

Is there something I am missing to allow for all phones / tablets to use my app?

This is my Manifest:

   <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="xxx"
      android:versionCode="xx"
      android:versionName="xx">
    <uses-sdk android:minSdkVersion="10" android:targetSdkVersion="17" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>
    <uses-permission android:name="android.permission.CAMERA" />

    <supports-screens 
                      android:smallScreens="true"
                      android:normalScreens="true"
                      android:largeScreens="true"
                      android:xlargeScreens="true"
                      />
    <application android:icon="@drawable/icon" android:allowBackup="true">
        <activity android:name=".ItineraryHomeActivity"
                     android:theme="@android:style/Theme.NoTitleBar"
                  android:label="@string/app_name"
                  >
                  <intent-filter>
                    <action android:name="android.intent.action.MAIN" />
                    <category android:name="android.intent.category.LAUNCHER" />   
                </intent-filter>
                <intent-filter>
                  <action android:name="android.intent.action.VIEW" />
                  <category android:name="android.intent.category.DEFAULT" />
                  <data android:scheme="file" />
                  <data android:host="*" />
                  <data android:port="*" />
                  <data android:mimeType="*/*" />
                  <data android:pathPattern=".*\\.tgtp" />
                </intent-filter>
                <intent-filter>
                    <action android:name="android.intent.action.VIEW" />
                    <category android:name="android.intent.category.DEFAULT" />
                    <category android:name="android.intent.category.BROWSABLE" />
                    <data android:mimeType="text/xml" />
                 </intent-filter>

        </activity>

        <activity android:name=".EditHomeItListActivity" android:configChanges="keyboardHidden|orientation" android:label="@string/itinerary_title"
        android:theme="@android:style/Theme.NoTitleBar" android:windowSoftInputMode="stateUnchanged"
         />

    </application>
</manifest>  

Shouldn't this make the app available to every single android device running 2.3.3 an above?

Answer 1

I figured it out. The line that says you need camera permission was being used as a filter in the google play store:

<uses-permission android:name="android.permission.CAMERA" />

I don't know why this was the case because all of the phones / tablets that didn't work already had a camera... but the fix was to change it to the "uses-feature" tag instead and not make it required:

 <uses-permission android:name="android.permission.CAMERA" />

Hope this helps someone
