What should I know about safe use of mobile devices?

Nowadays we keep a lot of private information on mobile devices (phones, smartphones, tablets), which is used not only for communication (calls, text messages, and e-mails), but increasingly also for various online and bank payments.

It may happen that while you left your mobile device unattended for just a few moments, someone managed to use it to send premium-rate text messages, causing unwelcome financial “surprises”, or transferred all of your personal data to another mobile device. If you are not cautious, your device might become infected by malware – and then it will be controlled by someone else.
