Black screen during Whastapp call/audio

My proximity sensor is broken, and, Whastapp turns the screen off during call/audio. Not even power button will turn it back on. All "solutions" out there tell me to clean the sensor. Impossible here. How to disable this completely ? I've tried Xposed's Disable Sensor module, entirely disabling this sensor or mocking it's values. No results. I thought about revoking a sensor usage permission for that app, but could not find a module that has such an option I can't remember if the problem happens during phone calls, but if the fix could be extended to this area, great Xperia Z3
