After updating to EL30, I am finding that the touchscreen is not as responsive as it used to be. For instance, to bring up the dialer, I have to frequently press the icon more than once before it responds. If I want to launch the web browser, I have to press the web icon more than once. If the phone is already unlocked, this doesn't seem to happen. This wasn't a noticeable problem when the phone was on EI22.
