Android System is uniquely characterized, which is slowly responsive within 24hours using. It doesn't seem to be a new subject.
Indifferent from the norm, the system UI your company is providing (for this modal) has not been stablized and running at its utmost capacity. Frankly your UI is not as smooth as some of your rivals', like Samsung, Huawei, or even Oppo for midrange smartphones.
Hope things get better in the next System Update. Basically we dont need more functions, rather the functionality of the phone.
