If you too were having problems with your Samsung Galaxy 3/Apollo/I5800/I5801 phone not being recognized by Windows, look no further.
1. You will need to download the drivers for another phone called Samsung Galaxy S.
For Windows (XP/Vista/7) x86 (32 bits).
For Windows (XP/Vista/7) x64 (64 bits).
2. Locate the file you downloaded and unzip its contents. Plug in your Galaxy 3 using the USB cable and redirect the driver installer to the folder where you unzipped the contents. If the driver installer doesn't show up, you can go to Control Panel > System > Device Manager then look for the problematic device, right-click, select Update driver...
3. The USB drivers should install correctly and your phone will be recognized by Windows.
