Also force press doesn't work very well, you have to press and hold it for a couple of seconds before finding out if that even works on that particular screen you are on
I didn't have an issue initiating force touches, but maybe there is a manufacturing inconsistency?
Also, it seems like people tend to hold their finger when force touching, but I found you could just press harder and don't have to hold your finger there; either the force press menu would appear, or the screen would do the force press animation and no menu.
