In Android we do have an option to go directly to App Usage Settings screen by firing below intent :
Intent intenta = new Intent(Settings.ACTION_USAGE_ACCESS_SETTINGS);
But there are few devices in Samsung and LG (not all) which has customized OS and does not take directly to "APP USAGE ACCESS" screen even after firing above intent, rather it just takes user to "SETTINGS" screen. My question is how do I identify such devices and separate them so that I can take care of their actions separately
