I always delete these applications after installing GSI or custom ROM, maybe there is a slight change in the operating system startup speed, you can also delete it if you like, of course if you don't need it.
Android Auto
Android Accessibility Suite
Google Calender
Pixel Safety
Recorder
FM
Default Camera ( like Gcam light )
Try to remove other system apps that you don't use. It's completely personal. You can do this with
Lucky patcher or remove it manually by
Mt manager, I don't recommend app manager for this.
