[QUOTE="lavacarancher, post: 1263631, member: 9198"] Jo, I ain't no doctor and I don't want to sound geeky but … There are three major technologies used in touch screens for phones (or tablets), SAW (Surface Acoustic Wave), capacitive and resistive. SAW and capacitive should not be affected by changes in body chemistry or electrical influence. Resistive can and will be affected. As we age, for what ever reason, the moisture in our skin dries up and we lose the ability to do a variety of things like turning the page of a book or opening jars or …. Human skin is really not a very good conductor of electricity and becomes less of a conductor (more resistive) when dry and if your phone uses resistive technology on the touch screen it will become less functional as the skin dries. Try getting your hand wet, dry it off and then try to operate your phone. I will be interested to see if this guess is correct. If all else fails get yourself a stylus and carry it in your pocket. You can use it to control your phone touch screen instead of your fingers. Also, don't try to use the touch screen immediately after palpating your cattle. Cow poop is not good for the phone either. :shock: [/QUOTE]
