I own a redmi 9 pro for a few days now and overall it's a nice device that i like but i face a serious problem since day one. The phone keeps losing wi-fi connection. It looks like it's connected to internet but it isn't. When the phone is locked and i unlock it i have to turn off wi-fi and then turn on to get connected to internet. This happens every time i unlock the phone and want to use internet. In the meantime i don't get any notifications. Very big problem. I am really tired and disappointed of this. My previous phone redmi 6 pro had no problems at all
