I have a Nokia Lumia 520. My phone memory is full, so I'm not able to download new games. Is there any way to download games/apps to SD memory?
Starting with v8.1 which was released to those on the "Preview for Developers" yesterday, the new Storage Sense app allows for apps to be stored on the phone, or on the SD card.
This update is due to be rolled out to all phones running 8.0 over the "next few months", and availability will vary by phone manufacturer and, in some cases, network operator.
You can download them from the store in a SD card and you can install them from there. But the apps still need to be installed in your phone's internal memory.
So you need free space in your phone to use more apps. SD cards are useful to store music, video and photo. In summary only media content.
In some leaked version of Windows Phone 8.1 SDK they said will be possible to install apps in the SD card
