How do I remove lock symbol from iPhone 8?

The lock symbol on an iPhone 8 typically refers to the device being locked or in sleep mode. To remove the lock symbol and wake up your iPhone, you can follow these steps:

1. Press the Side or Sleep/Wake button (located on the right side of the device) once.
2. If prompted, you may need to enter your passcode, use Touch ID, or Face ID to unlock the device.
3. After unlocking, the lock symbol should disappear, and you will be able to use your iPhone normally.

If you're referring to a different lock symbol, kindly provide more details so that I can assist you more accurately.
