Touch screen cell phones are no more or less dangerous than any other cell phone. The danger comes from the magnetic field generated by the high frequency (usually PCS - which is in the microwave range) carrier, and you get that by holding the phone close to your ear while talking. But the relative size (not to mention the strength) of the field generated by the electronics needed for the touchscreen is minimal compared to the carrier frequency, so before you are talking on the phone (i.e. using the touch screen), there is no danger.
Some users of mobile handsets have reported feeling several unspecific symptoms during and after its use; ranging from burning and tingling sensations in the skin of the head and extremities, fatigue, sleep disturbances, dizziness, loss of mental attention, reaction times and memory retentiveness, headaches, malaise, tachycardia (heart palpitations), to disturbances of the digestive system. Reports have noted that all of these symptoms can also be attributed to stress and that current research cannot separate the symptoms from nocebo effects
Avoiding injuries from typing and tapping. The position of your wrist also affects the likelihood of injury from performing multi touch gestures on touchscreens. According to Alan Hedge, director of the Human Factors and Ergonomics Laboratory at Cornell University, the more you dorsiflex your wrist, the greater the chance of injury. But, he adds, most gestures don't require too much force, so you're usually safe as long as you don't bend your wrist excessively or repeat gestures too rapidly.
