After using this app. The loud speaker on Samsung note 8, 9 doesn't work for other apps. The sound comes thru the ear piece even when loud speaker is activated. But this is rectified when the jumblo app is closed. But after updating to android pie on galaxy note 9, this problem doesn't go away even after closing the jumblo app and the phone needs to be restarted. Pls rectify this.
