Dynamic Island gone wrong

I dont know about you guys but my Dynamic Island on the 15 Pro doesnt seem to be working right. When i switch apps quickly, there are times when the whole Dynamic Island moves only to the right. Another issue i encountered was whenever i open notification centre and press the side button to turn off screen, the screen flickers and both brightness/volume slider moves up and down on its own. This has occured on my previous iPhone 14 Pro Max too. Genius Bar has inspected my phone and suggested getting it repaired, is it worth?
