This follows up the previous discussion on how to make mobile projects respond quicker to click events.
Since some mobile connections can be slow to send click events to the server, and then navigate/refresh screen, I have been noticing some frustration with some users. The feeling is that the screen does not respond to clicks, and that leads to clicking multiple times, pressing harder on the screen, and the like.
My suggestion is, add an hourglass (or similar) icon to the top corner of the screen. When a click event is detected on the phone, display the hourglass. When the server responds (possibly after a few seconds), hide the hourglass.
This way, the user knows that the click was indeed detected and s/he just needs to wait.
