Unmuting makes my phone ring
I have recently started using a second-hand Redmi Note 7. Just today, I found that when I mute the phone and then unmute it, it plays my ringtone with no way to stop it except re-muting it, until the entire song has played out. The person who owned it previously said that never happened before. The phone did just update to MIUI Global 12.5.3. I don't think I muted or unmuted it prior to that, so I don't know if it's the update that's causing it. I can't find any kind of setting to make it stop doing that.
