Touch disable mode?

I bought a waterproof phone case. But if I want to unlock the phone (Huawei P10Lite) in this case, this message comes

Can you please tell me how I can disable the mode? I've already tried pressing the power button and the volume button, but it's not working.

Does this phone have face recognition? Then, of course, the camera must be free… Disable the face recognition, then the message should disappear.

So in my HUAWEI I can turn off the message about the "pocket mode" in the smart support menu in the settings.

You can unlock it with the message anyway, is how it works. Simply volume button and unlock button at the same time.

That's just there, that you can't accidentally unlock the phone in the bag. I have it with me, but you can turn it off.

No, the phone has no face recognition

Settings - -> intelligent support - -> Pocket mode (bottom) off
