Huawei offers the system navigation “Gestures” where you can navigate by draggin from certain edged of your screen. By for example dragging from the left/righ screen edge you can go back. This naviagtion doesn’t work when inside the Blloc apps. Which makes it extremly impossible to go back, go to the recent apps menu when inside the start menu of Ratio and to leave the options menu.
