OMG.. I FOUND A SOLUTION.....
INSTALL FULL SCREEN GESTURES APP...
U all can ****ing thank me...
Really Nice find ,haha
I notice it's still overlapping ...u swipe upper half part of the screen from left to right it's miui gesture, lower half of the screen from left to right or right to left it's full screen gesture. From bottom swipe up still miui gesture.....
But good enough ...a pity there's no "last app" option via long drag from left right option
At least it's not killing off the app so far ... Fluid nagvaition don't know why will ki siao auto switch off
