1. The phone freezes or operations are unstable: Restart the device. Press and hold the Power key, then tap Restart. Note that data that was being edited will be erased when the device is restarted.

2. The device starts freezing after installing a new app: The newly-installed app may be causing the device to freeze. Uninstall the app in Safe mode. To enable Safe mode, press and hold the Power key, then touch and hold Power off. Read the disclaimer for Safe mode, and then tap OK. After turning the phone on in Safe mode, "Safe mode" will appear at the bottom left corner. After restarting in Safe mode, your phone can be powered on as usual. Before enabling Safe mode, it is recommended that you back up important data. To exit Safe mode, restart the device. Press and hold the Power key, then tap Restart. The phone will reboot in normal mode.

3. The phone will not make calls, send messages, check email, or connect to the Internet: 

• The network signal may be too weak or you may be out of the service area. Return to an area with a strong network signal.

You can enable the Battery Manager to help identify which apps are draining the battery. From the Home screen, swipe up to access Apps and tap Settings > Battery > Battery Manager and slide the switch to the On position.

5. An app will not download or install: 

• Make sure the device has room for the app. Apps may not be installed with minimal free space on the phone or SD card. To check free storage space, see "Storage" on page 153.
