Whenever i turn my SG S4 (GT-I9505) on or restart it, i get a 'currently unable to download. Please try again later' message at the bottom of my screen. All of my apps are up to date, recently downloaded 4.4.2 and play store 4.6.17. I haven't allowed third party apps but have turned off some permissions for some apps via app ops starter. Is it just a bug with the new firmware or what?
