For the center of the keyboard, the touch feeling is good. You could get a clear response when the key is pressed, and the screen shows what you have pressed.
For the margin of the keyboard, some key has a really slimy touch response. I do not really know whether it is pressed and send the keypress to the system.
Can I ask do you have the same situation, or if there is any method to fix it ?
I have checked if there is something stuck under the key case/keyboard, but I cannot find anything wrong. I also compare a normal key with a slimy key, but I cannot find if there is any difference (I am not familiar with hardware, maybe I have omitted something).
