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 quite quickly – and then it will be controlled by someone else.
