RohithTony because they want to copy IOS.
apple started it and everyone is copying it as usual. and you can see which one looks better.
nothing started with clean experience and y’all want nothing to copy IOS just coz everyone doing it? theres app in playstore called IOS control center. that might give what you asking for.
and just coz every company is having it doesnt mean nothing has to copy that as well. its design signature. every company has different control panel. have you seen google pixel having volume slider? google itself made android
