Precedents:
On Apple Music, users may mis-tap the icons on the tab bar when triggering player screen. The player bar is good for Spotify as it doesn't have a tab bar. So I designed a small vinyl on either sides of screen for triggering player screen. As a result I can keep the tab bar and lower the chance of mis-tapping. (I have to keep tab bar, because users can double tap the icons to return to main screens.)
For adjusting time, it's ok to use the traditional way. But it's not intuitive enough. Besides we have to press those small dots.
