First time I opened the app, it asked me to rate it. Hello!? How can I rate the app if I haven't used it yet. Then I played the song I like. It was playing for ≈1min, and then another song turned on. What?! I didn't ask for it! Some other app was installed on my phone with Shazam app. It doesn't have name, I can't neither open it nor delete. After I uninstalled Shazam, that app didn't disappear. I can't remove it. I have no idea what to do with it, and what changes it could make to my phone.
