Connect to Wi-Fi networks
 
Turn Wi-Fi on and connect to a Wi-Fi network
If you're adding a Wi-Fi network when first setting up your phone, Wi-Fi is turned on automatically.
  • Touch Settings > Wireless & networks > Wi-Fi.
  • Slide the Wi-Fi switch to the On position.
    The phone scans for available Wi-Fi networks and displays the names of those it finds. Secured networks are indicated with a Lock icon. If the phone finds a network that you connected to previously, it connects to it.
  • Touch a network name to see more details or connect to it, and type a password if necessary.
    Or, if your Wi-Fi router supports Wi-Fi Protected Setup, touch the WPS icon on your phone, and then touch the same button on your router.
To modify a network's settings, touch & hold the network name.
 
Tip: To extend the life of your battery between charges, turn off Wi-Fi when you're not using it. You can also set your phone to disconnect automatically from Wi-Fi networks when it's sleeping.
 
Add a Wi-Fi network
You can add a Wi-Fi network so that your phone will remember it, along with any security credentials, and connect to it automatically when it's in range. You must also add a Wi-Fi network if the network does not broadcast its name (SSID), or to add a Wi-Fi network when you are out of range.
 
To join a secured network, you first need to learn security details from the network's administrator.
  • Turn on Wi-Fi, if it's not already on.
  • Touch the Plus icon.
  • Enter the SSID (name) of the network. If necessary, enter security or other network configuration details.
  • Touch Save.
The information about the network is saved. Your phone will connect to this network automatically the next time you come within range.
 
Forget a Wi-Fi network
You can make the phone forget about the details of a Wi-Fi network that you added—for example, if you don't want the phone to connect to it automatically or if it's a network that you no longer use.
  • Turn on Wi-Fi, if it's not already on.
  • In the Wi-Fi settings screen, touch the name of the network.
  • Touch Forget in the dialog that opens.
Configure proxy settings for a Wi-Fi network
Some network administrators require you to connect to internal or external network resources via a proxy server. By default, the Wi-Fi networks you add are not configured to connect via a proxy, but you can change that for each Wi-Fi network you've added.
 
Proxy settings are used by Chrome but may not be used by other apps.
  • Touch & hold a network in the list of Wi-Fi networks you've added.
  • Touch Modify network in the dialog that opens.
  • Select Show advanced options. (You may have to lower the keyboard first. To do so, touch the modified Back button.)
  • If the network has no proxy settings, touch None under Proxy Settings, then touchManual in the menu that opens.
  • Enter the proxy settings supplied by your network administrator.
  • Touch Save.
The proxy settings apply only to the Wi-Fi network you modified. To change the proxy settings for other Wi-Fi networks, modify them individually.
 
Set Wi-Fi notifications, disconnect policy, and other advanced options
To work with advanced Wi-Fi settings:
  • Turn on Wi-Fi, if it's not already on.
  • In the Wi-Fi settings screen, touch the Menu icon and choose Advanced.
These are the settings you can adjust:
  • Network notification: By default, when Wi-Fi is on, you receive notifications in the Status bar when your phone detects an open Wi-Fi network. Uncheck this option to turn off notifications
  • Keep Wi-Fi during sleep: To conserve mobile data usage, your phone stays connected to Wi-Fi when the screen goes to sleep.
    Touch this option to change this default behavior: either to stay connected to Wi-Fi only when the phone is connected to a charger (when battery life isn't a problem), or never to stay connected to Wi-Fi during sleep. The latter choice is likely to increase mobile data usage. You may want to revisit this setting if you receive a notification that you're approaching your specified mobile data limit.
  • Avoid poor connections: Check to automatically avoid using networks with a low-quality or intermittent Internet connection.
  • Wi-Fi frequency band: Specify Automatic, 5 GHz, or 2.4 GHz frequency bands.
  • Wi-Fi optimization: Check to minimize battery usage when Wi-Fi is on.
This screen also displays the following information:
  • MAC address: The Media Access Control (MAC) address of your phone when connected to a Wi-Fi network.
  • IP address: The Internet Protocol (IP) address assigned to the device by the Wi-Fi network you are connected to (unless you used the IP settings to assign it a static IP address).
Related settings
To turn Wi-Fi on or off, go to Settings > Wireless & networks > Wi-Fi.
To manage mobile data options, go to Settings > Wireless & networks > Data usage.

Connect to Bluetooth devices

To connect to a Bluetooth device, first turn on your phone's Bluetooth. Then, the first time you use a new Bluetooth device, you need to "pair" it with your phone so that both devices know how to connect securely to each other. After that, they connect automatically.
 
Tip: To extend the life of your battery between charges, turn off Bluetooth when you’re not using it. You may also be required to turn Bluetooth off in some locations. Bluetooth is turned off when you switch to Airplane mode.
 
System bar icons indicate Bluetooth status. Turn Bluetooth on or off
  • Go to Settings > Wireless & networks.
  • Slide the Bluetooth switch on or off.
  • Change your phone's Bluetooth name
    Your phone has a generic Bluetooth name by default, which is visible to other Bluetooth devices when you connect them. You can change the name so that it is more recognizable.
  • Under Settings > Wireless & networks, make sure Bluetooth is turned on.
  • Touch Bluetooth.
  • In the Bluetooth screen, touch Menu > Rename phone.
  • Type a new name and touch Rename.
Pair your phone with a Bluetooth device
You must pair your phone with a device before you can connect to it. Once you pair your phone with a device, they stay paired unless you unpair them.
If the device you want to pair with isn’t in the list, ensure that it's turned on and set to be discoverable.
  • Under Settings > Wireless & networks, make sure Bluetooth is turned on.
  • Touch Bluetooth. Your phone scans for and displays the IDs of all available Bluetooth devices in range.
  • If your mobile device stops scanning before your Bluetooth device is ready, touch Search for devices.
  • Touch the ID of the Bluetooth device in the list to pair with it.
  • Follow the instructions to complete the pairing. If you’re prompted to enter a passcode, try entering 0000 or 1234 (the most common passcodes), or consult the documentation that came with the device. If the pairing is successful, your phone connects to the device.
Connect to a Bluetooth device
Once you've paired with a Bluetooth device, you can connect to it manually—for example, to switch devices or to reconnect after it is back in range.
  • Under Settings > Wireless & networks > Bluetooth, make sure Bluetooth is turned on.
  • In the list of devices, touch a paired but unconnected device.
  • When the phone and the device are connected, the device is displayed as connected in the list.
Configure or unpair a Bluetooth device
Some Bluetooth devices have multiple profiles. Profiles can includes the ability to transmit your conversations, play music in stereo, or transfer files or other data. You can select which profiles you want to use with your phone. You can also change the name of the Bluetooth device as it appears on your phone.
  • Under Settings > Wireless & networks, make sure Bluetooth is turned on.
  • In the Bluetooth settings, touch the Settings icon beside the connected Bluetooth device you want to configure.
  • A screen opens that allows you to change the device's name, unpair it, or select profiles. touch the Back button when you're finished.
Obtain a network connection via Bluetooth tethering
If you have a computer or other device that can share its network connection via Bluetooth, you can configure your phone to obtain a network connection by Bluetooth tethering (sometimes called reverse tethering).
  • Configure your computer to share it’s network connection via Bluetooth. See your computer’s documentation for details on how to do this. Typically, it involves making your computer discoverable via Bluetooth and allowing incoming PAN connections.
  • Pair and connect your phone to your computer via Bluetooth.
  • Go to Settings > Wireless & networks > More > Tethering & portable hotspot.
  • Check Bluetooth tethering.
  • Your phone connects to the Internet via Bluetooth and your computer, and a Bluetooth icon appears in the System bar.
Related settings
To turn Bluetooth on or off, go to Settings > Wireless & networks > Bluetooth.
To turn Bluetooth tethering on or off, go to Settings > Wireless & networks > More > Tethering & portable hotspot.

Optimize data usage
 
Data usage refers to the amount of data uploaded or downloaded by your device during a given period. Depending on the device and your wireless plan, you may be charged additional fees when your data usage exceeds your plan's limit.
To monitor your data usage, go to Settings > Wireless & networks > Data usage.
 

WARNING

 The usage displayed on the data usage settings screen is measured by your phone. Your carrier's data usage accounting may differ. Usage in excess of your carrier plan's data limits can result in steep overage charges. The feature described here can help you track your usage, but is not guaranteed to prevent additional charges.

 
Data usage settings allow you to:
  • Set the data usage level at which you'll receive a warning.
  • Set a data usage limit.
  • View or restrict data usage by app.
  • Identify mobile hotspots and restrict background downloads that may result in extra charges.
To view mobile hotspot settings, touch Menu > Mobile hotspots.
 
By default, when you open the data usage settings screen you see the settings for mobile data: that is, the data network or networks provided by your carrier:
 
snp2924597env0.png
 
It's possible to show Wi-Fi data usage settings in a separate tab. To do so, touch the Menu icon, then Show Wi-Fi usage.
 
Near the top of the screen, note the on-off switch for mobile data. The instructions that follow assume that this switch is turned on. If it's off, you won't be able to use mobile data at all and many features of your phone and apps won't work correctly.
 
Just below the on-off switch, note the data usage cycle. Touch it to choose a different cycle. This date range is the period of time for which the graph displays data usage.
 
The vertical white lines on the graph show a period of time within the data usage cycle. This range determines the usage amount displayed just below the graph. Drag lines to change the period.
 
Set auto-sync
You can also conserve data usage by syncing your apps manually, only when you need the data, rather than relying on auto-sync. To turn auto-sync off or on, touch Menu > Auto-sync data.
 
Set data usage warning
Drag the orange line by its right side to the level where you want to receive a warning.
 
When your data usage reaches this level, you'll receive a notification.
Set data usage limit
  • Check Set mobile data limit.
    A dialog appears that describes the limit you're setting.
  • Read the message. If you're willing to proceed, touch OK.
    The red line at the top of the graph activates, so you can drag it up or down.
  • Drag the red line by its right side to the limit you want to set.
    When your data usage reaches the limit, mobile data will be turned off automatically and many features of your phone won't work correctly. You'll receive a notification when this occurs.
View or restrict data usage by app
Some apps transfer data in the background—that is, when you're not actually using the app, it may download data for future reference. Restricting background data usage for individual apps can sometimes be a useful way to reduce your overall data usage. However, this is a drastic measure that may also affect the app's performance or cause it to malfunction. Check whether data usage can be restricted from the app's own settings (available from within the app) before restricting it here.
  • Make sure you're viewing the network for which you want to view or restrict app data usage. If more than one is displayed, you can switch between them by touching tabs at the top of the screen.
  • Scroll down to find the app whose data usage you want to view.
    The blue bar for each app indicates its total data usage for the cycle displayed above the main graph, near the top of the screen.
  • To see more details for an app, touch its name.
    The main graph switches to show just this app's data usage for the specified cycle. Below the main graph, a pie chart breaks out foreground versus background data usage for this app.
  • To stop background data usage for this app, check Restrict background data.
  • Read the message that appears. If you're willing to proceed, click OK.
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. This is an extreme step that should be used with caution.

Connect to virtual private networks (VPNs)
 
Virtual private networks (VPNs) allow entry into secured local networks from the outside. Corporations, schools, and other institutions use VPNs to grant access to local network resources when people are not on campus or connected to a wireless network.
 
To configure VPN access, you must first obtain the details from your network administrator. Depending on your organization's solution, you may need to obtain a VPN app, either from your administrator or on Google Play.
 
To view VPN settings, touch Settings > Wireless & networks > More > VPN.
 
Add a VPN
  • From the VPN screen, touch Add VPN profile.
  • In the form that appears, fill in the information provided by your network administrator.
  • Touch Save.
The VPN is added to the list on the VPN screen.
 
Connect to or disconnect from a VPN
  • From the VPN screen, touch the name of the VPN.
  • In the dialog that opens, enter any requested credentials.
  • Touch Connect.
When you’re connected to a VPN, a Status icon and notification are displayed continuously. To disconnect, touch the notification for the VPN connection.
 
Edit a VPN
  • From the VPN screen, touch & hold the name of the VPN profile.
  • In the dialog that opens, touch Edit profile.
  • Edit the VPN settings you want.
  • Touch Save.
Delete a VPN
  • From the VPN screen, touch & hold the name of the VPN profile.
  • Touch & hold the VPN you want to delete.
  • In the dialog that opens, touch Delete profile.
Set up an always-on VPN
Some VPNs support an always-on mode that won't permit network traffic if the VPN connection stops working. This can be useful, for example, if you're moving between unsecured public Wi-Fi access points and want to make sure that your VPN connection remains active and secure. If an always-on VPN connection is lost, you'll receive a notification and won't be able to send or receive data until the connection is restablished.
Before switching a VPN network to always-on mode:
  • Get detailed setup instructions from your administrator.
  • Add the VPN.
  • Connect to the network and, after providing your username and password, checkSave account information. This is required for always-on VPNs.
See above for instructions for adding and connecting to a VPN.
After you've set up the network and saved your account information:
  • From the VPN screen, choose Menu > Always-on VPN.
  • Select the VPN.
  • Touch OK.
A permanent notification keeps you informed of the always-on VPN's status.
 
To turn off always-on mode, choose Menu > Always-on VPN, then None and OK.

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 connection uses the MTP protocol, which is supported 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.
Windows transfer
  • Connect your phone to the USB port on your computer. Its USB storage is mounted as a drive and appears on your computer screen.
  • Copy files back and forth as you would using any other external device.
  • Disconnect the USB cable when you finish. (Some older versions of Windows may require that you eject the phone before disconnecting.)
Mac OS transfer
  • Install Android File Transfer from www.android.com/filetransfer, and follow the instructions there. (If you are using Android File Transfer for the first time, double-click it to open it. After the first connection, it opens automatically whenever you connect.)
  • Connect your phone to your computer with a USB cable. Android File Transfer starts, if it’s not already running, and opens a window that displays the contents of your phone, along with storage space details at the bottom of the window.
  • Work with this window much as you do in the Finder window: open and close folders, create new folders, and drag files to or from it and other Finder windows.
  • Disconnect the USB cable when you finish.
Related settings
To change your phone's USB connection options, touch Settings > Device > Storage > Menu > USB computer connection.

Extend battery life
 
To control Battery settings, go to Settings > Device > Battery.
 
You can extend your battery’s life between charges by turning off features that you don’t need. You can also monitor how apps and system resources consume battery power.
  • If you aren't using Wi-Fi, Bluetooth, or GPS, use the Settings app to turn them off. The GPS setting is located in Settings > Personal > Location access.
  • Don't leave the Maps or Navigation apps open on the screen when you're not using them. They use GPS (and thus more power) only when they're running.
  • Turn down screen brightness and set a shorter Sleep timeout: Settings > Device > Display.
  • If you don’t need it, turn off automatic syncing for all apps: Settings > Accounts > Google account name. This means you need to sync manually to collect messages, email, and other recent information, and won't receive notifications when updates occur.
  • If you know you won’t be near a mobile or Wi-Fi network for a while, switch to Airplane mode: press and hold the Power button, or go to Settings > Wireless & Networks > More > Airplane mode.

Check battery level and usage details
Open Settings > Device > Battery.
 
The list at the bottom of the screen shows the breakdown of battery usage for individual apps and services. Touch a graph for more details. The details screen for some apps includes buttons that allow you to adjust settings affecting power usage, or stop the app completely.
 

WARNING

 If you stop some apps or services, your device may not work correctly.

 
Battery status (charging, discharging) and level (as a percentage of fully charged) are displayed at the top of the screen.
 
The discharge graph shows battery level over time since you last charged the device, and how long you’ve been running on battery power.

Manage 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 in order to better manage your storage.
 
Important: 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.
You're able to optimize your memory usage by:
  • Uninstalling apps you don't use.
  • Deleting downloaded files or files you created and copying them over to a computer via USB.
  • Removing content from Google Play that's saved for offline use and streaming it via a Wi-Fi or mobile network.
Use the Apps screen
The Apps screen allows you to adjust several aspects of the way your device uses memory. To view these settings, go to Settings > Device > Apps.
You'll see three tabs at the top of the screen, each displaying a list of apps or their components:
  • Downloaded. Displays apps you’ve downloaded on Google Play or other sources.
  • Running. Displays all apps, processes, and services that are currently running or that have cached processes, and how much RAM they are using.
    The graph at the bottom of the Running tab shows the total RAM in use and the amount free. Below the graph, touch Show cached processes or Show running services to switch back and forth.
  • All. Displays all apps that came with Android and all apps you downloaded on Google Play or other sources.
To switch the order of the lists displayed in the Downloaded or All tabs, touch Menu > Sort by name or Sort by size.
 
To view details about an app or other item listed under any tab, touch its name. The information and controls available vary among different types of apps, but commonly include:
  • Force stop button. Stops an app that is misbehaving. Stopping an app, process, or service may cause your device to stop working correctly. You may need to restart your device after doing this.
  • Uninstall button. Deletes the app and all of its data and settings.
  • Disable button. Prevents the app from running, but does not uninstall it. This option is available for some apps and services that can't be uninstalled.
  • Clear data button. Delete an app’s settings and other data without removing the app itself.
  • Clear cache. If the app stores data in a temporary area of the phone's memory, lists how much information is stored, and includes a button for clearing it.
  • Launch by default. If you have configured an app to launch certain file types by default, you can clear that setting here.
  • Permissions. Lists the kinds of information about your phone and data the app has access to.

  • Fixed Dialing Numbers. GSM phones only. Set up your phone to place outgoing calls only to the fixed dialing numbers (FDN) that you save on the phone’s SIM card.
  • Call forwarding. Configure how your calls are forwarded when you’re on the phone, when you don’t answer, and so on.
  • Additional settings. For Caller ID, set whether your phone number is displayed to the people you call. For Call waiting, check to see and respond to new calls when you're already on a call.
Internet Call settings
  • Accounts. Choose to receive Internet calls for accounts added to your phone, view or change SIP accounts, or add an Internet calling account.
  • Use Internet calling. Use Internet calling for all calls, only for calls to Internet calling addresses (the default setting), or to ask for each call. You must be connected to a Wi-Fi network and have added an Internet calling account to your phone to use Internet calling.

Security on Android
 
Android takes a multi-layered approach to security:
 
Prevent. Apps in Google Play are scanned continuously to block harmful apps and policy violators. You can also choose to have apps installed from other sources verified.
 
Control. App “sandboxes” keep apps from accessing other parts of your phone's operating system, or each other, unless you give permission at installation. Screen lock and encryption help prevent unauthorized access to the entire phone.
 
Defend. Once identified, dangerous apps can be removed remotely.

Manage security settings
 
You can manage the security settings for your phone by going to Settings > Personal > Security.
  • Screen security. Manage screen lock options, such as using the Power button to lock your screen.
  • Encryption. Encrypt the data on your phone.
  • SIM card lock. Set up a PIN to lock your tablet's SIM card.
  • Passwords. Make passwords visible, which helps you to enter a password that is more complex and secure. 
  • Device administration. Manage device administrators, allow apps to be installed from sources other than the Play Store, and choose to verify apps from all sources.
  • Credential storage. Manage, install, or clear certificates on your phone.

TIP

Touch Owner info to enter information that's displayed on the lock screen. This is useful in case you lose your phone.

Protect against harmful apps

About verifying apps
Some applications can harm you or your phone. You can choose to verify apps in order to help prevent harmful software from being installed on your phone.
 
If you attempt to install an app from any source while app verification is turned on, your phone may send information identifying the app to Google.
 
If the app is harmful, Google may warn you not to install it, or it may block the installation completely.
 
Important: When you verify apps, Google receives log information, URLs related to the app, and general information about the device, such as the Device ID, version of the operating system, IP address, and one or more cookies.
Control app verification
App verification is turned on by default, but no data is sent to Google unless you agree to allow this when asked in the dialog that appears prior to installing the first app from an unknown source.
 
To control app verification, go to Settings > Security > Verify apps.
If you attempt to install an app that may be unsafe, you may see one of the following dialogs:
  • Installing this app may harm your phone. The app may be harmful to your phone and personal information. 
snp2812855env0.png
  • Installation has been blocked. The app is harmful and can’t be installed.
snp2812914env0.png
 
Turn off app verification
If you wish to stop verifying applications at any time, go to Settings > Security > Verify apps, then uncheck the box.

Set screen lock
 
You can lock your screen for additional security. If a lock has been set, the screen locks when your phone's display goes to sleep.
 
If your phone's playing music when the screen locks, you can continue listening or pause the selection without unlocking.
 
To adjust your lock settings:
  • Go to Settings > Personal > Security > Screen lock.
  • Touch the type of lock you want and follow the onscreen instructions.
If you've previously set a lock, you must enter the pattern, PIN, or password to unlock the lock settings.
You can choose among these lock options, listed in approximate order of strength:
  • Slide provides no protection, but lets you get to the Home screen or Google Now quickly.
  • Face Unlock lets you unlock your phone by looking at it. This is the least secure lock option.
  • Pattern lets you draw a simple pattern with your finger to unlock the phone.
  • PIN requires four or more numbers. Longer PINs tend to be more secure.
  • Password requires four or more letters or numbers. This is the most secure option, as long as you create a strong password.
Tip: After you set up Face Unlock, look under Settings > Personal > Securityfor two additional settings: Improve face matching and Liveness check. Use these to make Face Unlock more reliable and secure.
Password tips: For best security, specify a password that
  • Is at least 8 characters long.
  • Contains a mixture of numbers, letters, and special symbols.
  • Doesn't contain any recognizable words or phrases.
Related settings
To change when your phone goes to sleep, go to Settings > Device > Display > Sleep.
To see your passwords when you input them, go to Settings > Personal > Security > Make passwords visible.
