Android google play support/unsupport list of devices when Country filter applied

Question

My application is published in the Google play with country filter as US. So the application is only available for US country. When i check the unsupported devices list, Its displaying lot of devices which should actually support the application. I added every tag in the Manifest to cover almost all the devices from OS version 1.6 and above.Then why these devices are displayed as unsupported devices?

Do the devices which are not available for the US country comes under the unsupported list in the Google play?

Please confirm.

I added below tags in manifest.

<supports-screens android:smallScreens="true"
                  android:normalScreens="true"
                  android:largeScreens="true"
                  android:xlargeScreens="true"/>
<uses-feature android:name="android.hardware.bluetooth" />
<uses-feature android:name="android.hardware.camera" />
All permissions

Do i need to add any thing my Manifest or can i omit the Google play unsupported device list?

Answer 1

Currently your application requires telephony to be supported by the device (note the "uses-feature" line related to telephony). For this reason it's not available on a large number of Android tablet devices.

To declare that telephony isn't a required feature of your application, set it to not required by adding this line to your manifest:

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

That said, for whatever parts of your code use telephony (make calls, etc), make sure they can react properly to devices where that hardware isn't installed, by hiding/disabling the relevant features, etc.

Answer 2

FWIW, I had to add

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

to get support on the Galaxy Tab2 10.1.
