Frozen phone

Hi this is a public forum so the posting of sensitive info is not advised like your phone number. As far as your phone you may need to let it just die if you are unable to power it off in anyway. Below I have posted instructions on how to perform a soft reset which won't lose your data and a hard reset which will erase everything.

Master reset from settings menu

A master reset restores the original factory settings and may delete your personal data on the internal storage, such as downloads, ringtones, images, apps, contacts, and Visual Voicemail. It does not delete data stored on the SIM card or SD card.

1. Back up data on the internal memory.
2. From any home screen, tap the All apps icon.
3. Tap Settings.
4. Scroll to 'Personal,' then tap Backup & reset.
5. Tap Factory data reset.
6. If your phone is password protected, you'll be prompted to enter your Pattern, PIN, or Password.
7. Tap RESET PHONE.

Master reset with hardware keys

A master reset restores the original factory settings and may delete your personal data on the internal storage, such as downloads, ringtones, images, apps, contacts, and Visual Voicemail. It does not delete data stored on the SIM card or SD card. If the device menus are frozen or unresponsive, you can master reset using hardware keys.

1. Back up data on the internal memory.
2. Turn off the device.
3. Press and hold the Volume up button, then press and hold the Power button at the same time until the phone turns on.
4. When the device powers on, release the Power button but continue to hold the Volume up button until the Recovery screen appears.
5. Use the volume buttons to scroll to 'Wipe data/factory reset', then press the Power button to select it.
6. Scroll down to 'Yes - erase all user data,' then press the Power button to select it. If your phone becomes unresponsive at any point during these steps, you can restart it by holding down the Power button for several seconds.

Soft reset with hardware keys

A soft reset is a simulated battery removal. This is used to power a device off when the screen is frozen or unresponsive and the device it has an internal battery that cannot be removed. It does not cause loss of personal data on the device.

Press and hold the Power button for 10 seconds to manually reset the phone.
