“After I updated my Samsung Galaxy S3 to Android 4.3, my phone downloaded the file ‘roball1.jpg’ I don’t know why. I Googled this photo, and it is a check made out to some random person (it exists in ImageShack). I was also able to see it in my phone, once. Since I deleted it, my phone continuously downloads this file. However, if I try to view it, it says ‘media not found’. The file does not appear anywhere in my phone either. Have you heard anything about this?”
The Possible Causes of the Galaxy S3 Auto Downloads File Issue
I tried to look for the said file in Google and the search yielded results which are indeed related to a check made to some person plus some other things related to an online home job scheme.
If you are quite sure that you haven’t downloaded the file yourself, then, there’s a big probability that it is a malicious file downloaded by one of your third-party apps (also based on the way it behaves). I strongly believe that it wasn’t caused by the 4.3 update.
Maybe it was in your phone all along before you updated and it was saved in your backup that’s why your Galaxy S3 auto downloads file whenever it syncs with your backup.
The Likely Fix for the Galaxy S3 Auto Downloads File Problem
The best way to prevent malicious files from entering into your phone’s system is by installing a reliable antivirus or anti-malware app. You can find plenty of them in the Google Play store. Also, uninstall any app that you find suspicious in nature.
Then, for a good measure, access your Google+ Auto Backup photos. Check if you have the same file stored there. If you find it there, simply delete it completely to prevent getting it over and over again even if you have already removed the file from your phone.
If the Galaxy S3 auto downloads file again even after the installation of the antivirus or anti-malware app and you are sure that your Google+ account does not have the annoying file, simply perform a Factory Reset to remove all the corrupted or altered system files in your device that may be triggering the issue. This will completely wipe even your important data though, so be sure to backup prior to this.
