Android: SMS blocked by ChatON app

I wrote an application that receives incoming SMS messages, saves it and displays it to users. Suddenly, my application stopped receiving SMS due to an update to the Samsung ChatOn application.

Here is my Manifest.xml:

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


 <receiver android:name="com.myapp.sms.service.SMSReceiver"
     android:permission="android.permission.BROADCAST_SMS" android:exported="true">
     <intent-filter android:priority="999">
         <action android:name="android.provider.Telephony.SMS_RECEIVED" />
     </intent-filter>
 </receiver>

I had this problem earlier with Hangouts, which started supporting SMS. So, at that time I added priority to 999 (maximum value) in the manifest file. And it worked.

But after a recent update to ChatOn, the app stopped receiving SMS. Please tell me how I can overcome this.

To work, I turned off the SMS option in the ChatOn application.

Any help is appreciated.
