It's an interesting question. Some of them are definitely from the OS (either Google or Samsung).
Looking through at categories of app where I have multiple, I'm seeing:
- Transport provider apps (Airlines, Trains, Buses, Taxis etc)
- Parking payment apps
- Food delivery apps
- Hotel apps
- Payment apps
- Messaging / Video calling apps
- Banking apps
- Mapping apps
It's especially easy to accumulate a lot of apps if you travel through multiple countries, as for a lot of these apps you need different ones in different countries.
