When creating Android app, uses-feature and uses-permission are used inside manifest, but this might cause unwanted filter-outs.<\/p>\n

In my app, I first had manifest as<\/p>\n

<uses-permission android:name=&quot;android.permission.CAMERA&quot; \/>\r\n\r\n<uses-feature android:name=&quot;android.hardware.camera.autofocus&quot; \/>\r\n<uses-feature android:name=&quot;android.hardware.camera&quot; \/><\/pre>\n
but since app was usable without camera, I’ve changed to as follows for request from user who wanted to use app with device \u00a0without camera.<\/p>\n
<uses-permission android:name=&quot;android.permission.CAMERA&quot; \/><\/pre>\n
However, this didn’t list up app in Google Play. I had to write like this:<\/p>\n
<uses-permission android:name=&quot;android.permission.CAMERA&quot; \/>\r\n\r\n<uses-feature android:name=&quot;android.hardware.camera.autofocus&quot; android:required=&quot;false&quot; \/>\r\n<uses-feature android:name=&quot;android.hardware.camera&quot; android:required=&quot;false&quot; \/><\/pre>\n
Write uses-feature for camera, and add android:required=”false” parameter to clarify camera is not required.<\/p>\n
Android device with front-only camera device was also filtered in first 2 manifest code.<\/p>\n
Not only camera, location and bluetooth, which was part of function but not mandatory to app, was causing device without GPS and Bluetooth to be filtered out due to uses-permission option.<\/p>\n
I finally got over 1000 additional device supported, by writing manifest like follows.<\/p>\n
<uses-permission android:name=&quot;android.permission.INTERNET&quot; \/>\r\n<uses-permission android:name=&quot;android.permission.WRITE_EXTERNAL_STORAGE&quot;\/>\r\n<uses-permission android:name=&quot;android.permission.VIBRATE&quot;\/>\r\n<uses-permission android:name=&quot;android.permission.ACCESS_COARSE_LOCATION&quot; \/>\r\n<uses-permission android:name=&quot;android.permission.ACCESS_NETWORK_STATE&quot;\/>\r\n<uses-permission android:name=&quot;android.permission.BLUETOOTH&quot;\/>\r\n<uses-permission android:name=&quot;android.permission.BLUETOOTH_ADMIN&quot;\/>\r\n<uses-permission android:name=&quot;android.permission.CAMERA&quot; \/>\r\n\r\n<uses-feature android:name=&quot;android.hardware.bluetooth&quot; android:required=&quot;false&quot; \/>\r\n<uses-feature android:name=&quot;android.hardware.camera.autofocus&quot; android:required=&quot;false&quot; \/>\r\n<uses-feature android:name=&quot;android.hardware.camera&quot; android:required=&quot;false&quot; \/>\r\n<uses-feature android:name=&quot;android.hardware.location&quot; android:required=&quot;false&quot; \/>\r\n<uses-feature android:name=&quot;android.hardware.location.gps&quot; android:required=&quot;false&quot; \/>\r\n<uses-feature android:name=&quot;android.hardware.location.network&quot; android:required=&quot;false&quot; \/>\r\n<uses-feature android:name=&quot;android.hardware.touchscreen&quot; android:required=&quot;false&quot; \/><\/pre>\n
Point is writing\u00a0\u00a0required=”false” for non-mandatory features.<\/p>\n
You can check supported and filtered out devices from Developer Console, under APK.<\/p>\n
