This happens to me too with the whatsapp messages. Maybe the proximity sensor is buggy.Hi all! Thanks for the update, it's working as supposed on my mi 11 ultra! I would like to inform that I'm suffering with the same bug others have mentioned here before. Sometimes the screen gets dark after playing Whatsapp audio messages and the only way to make the screen work again is to press several times the power button to enter on emergency call or to restart the phone. Also, my smartwatch (mi Band 7 pro with mi fitness app) no longer receives notifications from the phone.
