Noted

May I ask you if you have any other device to log in to your Google account, please?

Just to clarify, please. What data you do not want to lose, just to be sure if we can save it with google, please?

I got you. May I ask you to use your laptop to check if your photos synced with Google services, please?
You need to open Google Photos or open this link photos.google.com and log in with your Google account if it asks you to do this.

Check if there are your last photos, please. To be sure you don't lose them, please.

May I ask you to enter an incorrect pattern or PIN five times on the lock screen? You'll see a “Forgot pattern,” “forgot PIN,” or “forgot password” button appear.

And no button appears, please?

I'm sorry this situation happened to you, *****. Unfortunately, there are two ways to bypass your pin code to enter the right one or do a hard reset and erase it.

In this situation, you can remember/guess your password or erase data on your phone including the lock screen pin code.

Just to clarify, please. Do you need help with how to do that, please?

To erase data on your phone you need to follow the next steps, please:

1. Power off your phone.
2. You need to press 2 buttons same time to enter recovery mode. Volume up and Power. You need to hold them until the phone logo appears.
3. After you see an android robot on the screen you need to press the Power button and Volume up once. You will see a list of options.
4. Next with the volume buttons choose to Wipe data / Factory reset and press Power to open this option.
5. After again with the volume buttons choose Factory data reset and press Power once.

After you complete this instruction you need to choose Reboot to the system now with the Power button, please.

Do you mean "wipe", please?
Just to be sure you acting in the right way, please.
