My dad did a screen time on my phone?

My father has inserted a screen time in my Huawei mate 9 that I want to bypass when I take a screen capture the phase by entering the password for an extension is shown in black. Can anyone help me get around it?

Reset your phone, uninstall the app, switch to flight mode and change the manual time.

Thanks but it was not done with an app but with the system

What does your father use for this?

Then reset cell phone

How much time did he give you?
