Can I remove the Android permission request on Startup in Unity 5.1.4 ?

I am currently using Unity 5.1.4 in my game. On Android 6 Unity is asking for dangerous permissions beforehand, which scares away some of my players.

In Unity 5.2.4 this issue has been resolved:

From the Changelog: Android: Android 6.0 - Ask for any dangerous permission on startup. (739831), (732504)

Unfortunately Unity 5.2 has introduces some performance regressions which prevents me from using this or newer version. I tested all versions until 5.3.1and all of them have the performance issues.

Is there a way to prevent those permissions from being asked?

Add this parameter into your AndroidManifest.xml:

<meta-data
    android:name="unityplayer.SkipPermissionsDialog"
    android:value="true"
    />
