Re: why my Samsung s3 show Ads on home screen?

Welcome to Android Central! Some adware or malware must have installed itself to your phone. This might have piggybacked on some other app you installed. Do you install all apps from Google Play Store, or other sources?

Try uninstalling apps one by one until the behavior goes away. Alternatively, do a factory reset, then after the Setup Wizard, go immediately to the Play Store and stop any app from installing automatically. If the behavior persists, then the malware likely installed to the system root, which can be tough to get rid of. You could try reinstalling the firmware, either with Samsung Kies or Odin: http://forums.androidcentral.com/am...w-flash-stock-rom-via-odin-new-interface.html
