Advanced data usage settings
Two other settings available from the Menu icon can have dramatic effects, but may sometimes be useful:
 Data roaming can result in steep additional charges. However, in some locations this may be the only way to connect to the
Internet.
 Restrict background data affects all your apps across all available networks, and may cause some features to stop working. Th is
is an extreme step that should be used with caution.
Optimize memory usage
You typically don't need to worry about managing apps beyond installing, opening, and using them. But there may be times when you
want to know more about what's happening behind the scenes.
Apps use two kinds of memory: internal storage and RAM. They use internal storage for themselves and any files, settings, and other
data they use. They also use RAM (memory designed for temporary storage and fast access) when they're running.
Android manages and carefully guards the portion of internal storage where the system, apps, and most data for those apps are stored,
because this area may contain your private information. It's not possible to view this portion of internal storage when you connect your
device to a computer with a USB cable. The other portion of internal storage, where music, downloaded files, and so on are stored,
remains visible for your convenience.
Android also manages how apps use RAM. It may cache some things you've been using recently, for quicker access if you need them
again, but it will erase the cache if it needs the RAM for new activities. You affect the way apps use internal storage directly and
indirectly in many ways; for example, by:
● Installing or uninstalling apps.
● Downloading files in Browser, Gmail, and other apps.
● Creating files (for example, by taking pictures).
● Deleting downloaded files or files you created.
● Copying files between your device and a computer via USB.
You rarely need to manage the way apps use RAM. But you can monitor apps' RAM usage and stop them if they misbehave.
Use the Apps screen
The Apps screen allows you to adjust several aspects of the way your device uses memory. To view these settings:
