With You: Don’t ever leave your phone unattended, especial y at public places. Letting it lie in the open gives others an opportunity to access your data. Always carry your phone in the pocket or in the handbag.
Password: Even if you don’t have any sensitive data on your phone, password protection is a must. Most smartphone maker such as Nokia, Samsung, Motorola, Apple iPhone, BlackBerry and Windows Phone has build in password capability. Google’s Android smartphone offers you a host of options—PIN, pattern, face, face and voice recognition (depending on the handset and OS version). Never use your name, birth date, address, car number plate, etc, as the password. In certain devices, there is the option to wipe the phone clean after a defined number of wrong password attempts.
Usage: As on your PC, avoid opening links or downloading attachments in emails from unknown sources. Also, only download third-party applications from official application
stores. Always make sure you check the app review and the source before downloading. Plus, while using Wi-Fi hotspots, avoid keying in your password and credit card details.
