Sir my samsung champ c3303 not support any download file ,game , antivirus mobile , invalid file show

Hi devendra,
i have tried to download, save and run applications saved on my memory card to my samsung champ and it works fine. you have to make sure that what you are downloading is/are compatible with your samsung champ. try to download from this site, this is where i got some of my apps http://www.mobileheart.com/cell-phone-softwares/2274-Samsung-C3300K-Champ-Software.aspx a little limited compared with other phones. you may also want to try the samsung website.
once you have saved what you downloaded, to make it work, open the file then run the application. wait until you see the prompt that it is already installed.
many thanks, nina

All download are sowing invaild
