Temporary fix. Simply tap uninstall. It will stop the download.. I tried to do that then do the update .... It worked Then I noticed later it was trying to download it again . Check your Google Update options Turn off auto update Apps . Also it is Set to update only over Wi-Fi, change that option To allow data update To Wi-Fi or data. But for this glitch that will not work but it will work for the rest of your Apps. Using Galaxy A715G
