able. For example, you can use Wireless Dis ­
play to show your phone’s screen on a T V

For more information, see the documenta ­
tion  that  comes  with  the  Miracast- cer tified 
device you wish to connect to your phone.

Transfer files through USB
You can use a USB cable to transfer music, 
pictures,  and  other  files  from  your  phone 
to a computer and vice versa. This connec­
tion uses the MTP protocol, which is sup ­
por ted by most recent versions of Windows 
but not by Mac OS X. For file transfer to Mac 
OS X, you use the free Android File Transfer 
application.

Manage memory usage
You typically don’t need to worr y about man ­
aging apps beyond installing, opening, and 
using them. But there may be times when 
you want to know more about what’s hap ­
pening behind the scenes in order to better 
manage your storage. 
						

							DEVICE SETTINGS 18 8
IMPORTANT: Android manages and 
carefully guards the por tion of inter ­
nal storage where the system, apps, 
and most data for those apps are 
stored, because this area may contain 
your private information. It’s not pos ­
sible to view this por tion of internal 
storage when you connect your de ­
vice to a computer with a USB cable. 
The other por tion of internal storage, 
where music, downloaded files, and so 
on are stored, remains visible for your 
convenience.
You’re able to optimize your memor y usage 
by:
• Uninstalling apps you don’t use.• Deleting downloaded files or files you cre ­
ated and copying them over to a computer 
via USB. 
• Removing content from Google Play
