One of the things that I like about Android smartphones is that you can easily connect it to your PC and use it as a storage device without installing any software. Not unlike iPhone which needs iTunes and WP7 phones that needs Zune.
However, that’s not the case for the Samsung Galaxy Ace (at least ours). When you connect it to your PC via USB, it will detect there’s a device connected to it but it will stop there. There’s no notification on your device to turn it into a Storage Device unlike in Galaxy S. You need to install Samsung Kies (Samsung’s phone manager) in order to access your phone from your PC.
This is one drawback of the Galaxy Ace. Other Android phones automatically install drivers to the PC once connected to enable Mass Storage mode but the Ace wants you to install the 60+MB Kies software that you probably won’t use afterwards (aside from updating). What if you want to connect it to a friend’s PC?
Well Samsung has a way out for this one. The reason why it’s not recognizing your phone as a mass storage device is that it’s set to USB Debugging mode by default.
Just go to Settings > Applications > Development and uncheck USB Debugging.
Once that is done, when you connect your Galaxy Ace to your PC, you will get the screen to Turn On USB Storage.
