Google Play developer console - nexus 7 is supported but cannot install apk

Question

I have published my first camera app, and in developer console currently there are 4282 supported devices and 0 excluded.

Three Nexus 7 models are listed in the supported list (1.Google Nexus 7 - flo, 2.Google Nexus 7 - deb and 3.Nexus 7), however i cannot install the apk on my Nexus 7 (2012) through Google Play saying it's not compatible. (i use to test my app on that device, it runs perfectly).

I know my manifest should include

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

to be compatible with Nexus 7, but why does it appear in the supported list?

Using the device availability dialog document states:

Device Availability provides a dynamic list of compatible devices based upon your manifest settings

so my Nexus 7 should not be listed!

Do i miss something?

EDIT

here's manifest permissions and features:

<uses-sdk android:minSdkVersion="9" android:targetSdkVersion="19"/>
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.WRITE_SETTINGS" />
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.INTERNET"/>

<uses-feature android:name="android.hardware.camera" android:required="true" />
<uses-feature android:name="android.hardware.sensor.accelerometer" android:required="true"/>

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

Answer 1

Adding

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

to the manifest file (although i wouldn't, because actually camera is required), 56 devices were added to the supported devices list, included two more Nexus 7, now they are:

GoogleNexus 7– grouper
Nexus 7
GoogleNexus 7– tilapia
GoogleNexus 7– deb
GoogleNexus 7– flo

I deduce that deb and flo are the new ones, with back camera, and old ones (v2012) are grouper and tilapia, i don't know about the ones labeled "Nexus 7" only.

Answer 2

Basically, some Nexus 7 devices do not need any user permission for Camera or WiFi, but has to be used the uses feature instead.

For example, use these

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

instead of

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

Answer 3

Does your G7 has camera? If not, it is correct that you cannot see it from GooglePlayStore on your G7 (since you have set require camera = true).

And another check point, might mean you should have a GPS.
