1. After several unsuccessful attempts, you will receive a warning message 'Try again in 30 sec. You have 5 tries left'.
2. Now, after 30 seconds, try unlocking your phone again.
3. In the lower left corner of the screen, the inscription 'Forgot Pattern' should appear. Tap on it.

4. Now you have to enter your Google account details. After this Google will send an email with the new pattern lock.

2. Use the Smart Lock function

Smart Lock automatically removes the screen lock when a certain condition is met. For example, if the device is in your home or if another of your devices connects to it via Bluetooth.

You can only use this feature if you have activated it beforehand and selected a condition to unlock it.

3. Use the service from the smartphone manufacturer

Some brands offer owners of their devices additional unlocking tools. For example, Samsung has a service called Find My Mobile, which can be used to remove the Pattern, PIN, password and even fingerprints. To do this, your device must be connected to the Internet and a Samsung account and support the service.

4. Reset the device to factory settings

If the other options don't work, you have to reset your device to the factory settings. This will result in the loss of all data, copies of which have not been saved to your Google account and other cloud services. But you will be able to remove the protection from the screen.
