I have a Xiaomi 11 Lite 5G NE phone and it started behaving weirdly recently. I noticed in my call log that I called 4 random people from my contacts list out of nowhere, randomly at all. I didn't even pull my phone out of my pocket, it called by itself. Another thing I noticed is that when someone calls me and when I pull the phone out of my pocket, I see that the call is already answered so I gotta put it on my ear and start talking, even tho there are calls that I'd like to avoid answering. On another hand, sometimes while pulling the phone out of the pocket it just denies the call. Do you know how can I fix these two issues?

Summed up, how can I fix randomly calling of people while my Xiaomi is in my pocket and how can I fix auto answering/denying while pulling out the phone from my pocket?
