I found a video solving similar issue on different phone. I'm very surprised. I disabled some function in developer settings and it looks like the issue is pretty much gone.
However thank you so much for help
Hey, here is the issue recorded. Please excuse bad quality. As I said before, it happens randomly, so first half of the video is Ok - without the problem. The problem occurs at 0:30

It doesn't happen while using headphones.
I know it happens when I get notification, but trust me, it happens randomly.
I'm gonna try to record it and give you a link so you can understand more
Few days after buying the phone I updated to Android 10, maybe it's not debuged yet? Unfortunately I don't know exactly when this problem occured. I noticed it few weeks ago. Last update was about 2 days ago, but the problem was already there.
I had about 25 - 30 apps installed by myself, most of them I uninstalled, now I have about 6 apps left - the most important ones. Do you think it's software issue or it's caused by hardware?
Yeah thanks for the link but unfortunately it it didn't help me. I don't know what to do, it's very annoying. I tried to uninstall about 15 apps as I read that some apps may affect this but nothing helped
