The iPhone and Android cell phone systems are well known, easy to use and useful for everyone. One of their shortcomings, as with all other systems, is their defenses, which can often be infected by viruses and damage your privacy and other very important things. The easiest way to prevent these viruses is to update the system from time to time to correct the flaws and increase the security of the device.
