1. Not setting a password
Setting a password on your phone is the first line of defense so that only you can access the important data on your phone. Your phone contains valuable information you want to keep safe: contacts, appointments, files, social network sites, passwords… if this information falls into the wrong hands, a password will help keep all of your sensitive data private.
2. Using public Wi-Fi
The recent explosion of free, public Wi-Fi has been an enormous boon for smart phone users. Since these free access points are available at restaurants, hotels, airports, bookstores, and even retail outlets, you are rarely more than a short trip away from access to a network. The same features that make free Wi-Fi hotspots desirable for consumers make them desirable for hackers, therefore, freedom comes at a price.
3. Shopping online through browser
4. Scanning unfamiliar QR codes
Like desktop browsers, mobile browsers are susceptible to attack by Trojan viruses. People use plug-ins to protect their online shopping when using PCs. However, there are no plug-ins for mobile smart phones.
We’ve been seeing a lot of these QR codes in magazines, on tickets, buses, business cards, TV, websites, on almost any object which we might want to learn more about. On the one hand, they’ve become great marketing tools for advertisers; on the other, cybercriminals have spotted their potential as a means of spreading malware, stealing identities and phishing for personal information. In other words, QR codes make things run faster and easier, but they can also pose a threat to your mobile security.
5. Clicking on links in text messages
Sending messages designed to trick the recipients into clicking on a deceptive link was once reserved for fake but real-looking email scams trying to fool users into visiting malicious sites on their PC, but scammers have realized there are far fewer protections on smart phones, and no small number of potential victims.
6. Making phone calls while charging
Using a cell phone while charging is dangerous due to increased radiation and potential for explosion or electrocution.
7. Making long calls
Mobile phones transmit radio waves through a series of base stations where radio frequency waves are electromagnetic fields that cannot break chemical bonds or cause ionization in the human body, says the World Health Organization (WHO). But adults and especially children might suffer the long-term effects of radiation waves on the brain. Preferably use the mobile only for messages and very short calls.
8. Sleep with your phone in bed
Some people are so attached to their cell phones that they sleep with them on their nightstand or even under their pillow. Cell phones pump out electromagnetic radiation whenever they’re on – which means sleeping with one nearby boosts your exposure all night long. What can you do? Put the phone on “airplane mode” (which shuts down the transceiver) or turn it off. If you need to be available for calls, place the phone several feet away from your bed.
9.Texting while walking
Many people think walking and using your phone poses no threat, but a study that attached sensors to the feet of subjects who texted as they crossed an obstacle course found they moved slower, dragged their feet and wobbled off the path.
10. Using smart phone behind the wheel
Cell phones can be life-saving communication tools to have on hand in a vehicle in case of emergency. However, actually using a cell phone while driving may be life threatening. Many different studies have shown that when drivers use a phone while driving, it can be very dangerous. At some point during the use of a cell phone, a driver’s eyes are bound to be distracted from the road.
