App ins't compatible with lots of smartphones / tablets

So, i created an app that works ok in about 4000 models of smartphones / tablets, but it ins't compatible with about 3000. (Data from google play). I understand that some aren't compatible because of the API, but in my nexus 5, with Android 4.4.2 the app works, but on a Samsung Tab S 8.4 with 4.4.2, is doesn't. Whats the problem?

I don't understand.

My guess is that the excluded devices are based on these two permissions:

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

Having CALL_PHONE by default makes the phone aspect of a device required, which is problematic for tablets. You can make it an optional feature, though, but adding a uses-feature set to false, like explained in this StackOverflow answer: http://stackoverflow.com/a/7883767/475217

Can you paste in the contents of one of these?

  1. If using Android Studio: build.gradle (in the app module)
  2. If using Eclipse: AndroidManifest.xml
