Many apps or games are designed to take advantage of specific hardware and software features of your Windows Phone. For example, a photo app might need to use your phone's camera, or a restaurant guide might need to know your location to provide nearby recommendations.
You can see what features an app requires by tapping the app in the Windows Phone Store and swiping over to Details. You'll see the app requirements listed at the bottom of the page. Apps are required to ask you for permission before they use certain phone features. If you don't want to allow an app to access something listed in the requirements, you can choose not to install the app.
Some apps and features won't work on phones with less than 1 GB of RAM. To see how much memory your phone has, check the manufacturer's website or your phone's documentation.
