There are many cool apps for smart phones. You need to be careful and review what type of permissions are required for these free apps.
Ask yourself…..Why does this app need to have access to my camera, location, contacts, etc.
We are seeing more and more of these free apps being used to carry malware. This malware can gain access to your camera and turn it on at anytime. Can track your whereabouts at all times (a little scary).
Make sure to read reviews and search online for the validity of the free apps you are interested in.
If you have kids with smart phones, keep track of what they are downloading as well.
