Review: Motorola Defy
Touch sensitivity was no problem on the Motorola Defy. Occasionally, the homescreens might lag a bit behind my swiping actions, but this was usually just after I powered up the phone, while all the Motoblur widgets are synchronizing. Once that was done, the phone responded quickly.
The touch buttons beneath the screen and the capacitive screen itself both worked well when wet. Capacitive technology does not work fully submerged in water, but after a second or two out of the pool, the phone responded with no trouble, even while there were still large drops on the phone's face. So, this is not the phone for SCUBA diving, more for living through a rainy year in Seattle.
