Good afternoon, evening, or good night, I need mom's support, lives in another city, leaves the country, but when testing with redmi note8 on my second rarely used xiaomi 4a, the lower on-screen buttons in the blue bar, home, back, etc. do not work d. You have to press them on 4a. I can't even go back to the home screen. Is there a solution in the settings, or will the buttons work in windows?
