Hello everyone
I accidentally turned the brightness of my Oukitel smartphone all the way down, so the screen is black
How can I turn it back to normal?
Thanks in advance to you

Thank you.
Problem solved.
You needed to press the square icon or the little house icon at the same time as the power button.
Turn off the device and then restart it.
Thank you.
