On redmi note 9s ,regardless /e/ os version ( always running latest available) sometimes speaker volume starts to rise by itself like someone is pressing button. I can stop it only by pressing button to decrease volume. Or sometimes when I press button to decrese volume it fights with phone which is increasing volume. Button is ok. It acts for few days like this and than it is ok.( I have MiA1 with e os as well and on this one volume up stop working sometimes.) Sometimes I find data and or bluetooth turned on. I didn’ t turned it on for sure. Today I found wireless emergency notification turned on. I always turn off all emergency related settings. What is going on? I have minimal set of applications mostly open source and two banking. Does anyone have similar issues?
