Summarize the following:
Once the phone has enough battery power, you can reboot it. Unlock your phone by pressing the Power button briefly then swiping the screen either left or right. If you have alternative security measures, unlock your phone with its respective code. You should now be in your home screen, which is where all your app shortcuts and widgets are located. All you have to do is hold the Power button to make the Power menu appear. In the Power menu, you will see power options like "Turn off," "Reboot," and "Airplane mode." Tap on "Reboot." If the phone gives a prompt, tap the "Reboot" button to initiate a reboot. You phone should turn off then on itself. Wait a few moments until the phone takes you to your lock screen. Unlock the phone using the unlock code (if you set up one) or by swiping the screen, and you should be good to go.
Unlock the phone's screen. Open the Power menu. Reboot your Note 2.
