On my Samsung S20 plus, sometimes, when a call comes in, there is no notification window appearing.. I have to swipe down the notification panel and then only I can receive the call.. What is this?? So annoying.. I have used oneplus for about 5 years...

Why can't we use Quad HD resolution with 120 Hz Refresh rate?? If Oneplus can do it, so does can Samsung.. We are waiting.. Hope you guys listen..
