Protect your smartphone from unauthorised access
Activate biometric security features such as fingerprint or face recognition to restrict access to your device. With biometrics, for example, there is no risk of third parties being able to spy on your access data as you enter it.
Always keep the software on your smartphone up to date
Keep the automatic update function for your operating system activated and always carry out updates as soon as they are offered to you. This way, new security updates will always be installed promptly. You should also always keep the apps installed on your device up to date. The easiest way to do this is to activate automatic updates in your respective app store.
Save your data regularly
Make regular backups of your personal data (photos, videos, documents, etc.). This will help you avoid data loss if your device is lost or damaged, for example. What's more, if you change devices, you can quickly transfer your data and settings to the new device using the backup.
For details, please refer to the user guides from Google for Android devices or the user guides from Apple for iPhones.
Activate the device location
Device location allows you to locate a lost or stolen smartphone, lock it or clear all your data by resetting your device to the factory settings. Most of the time, when configuring a new smartphone, you will be asked whether you want to activate device location. However, you can also do this later in the settings.
For details, please refer to the user guides from Google for Android devices or the user guides from Apple for iPhones or iPads.
Check the permissions of your apps
As a general rule, only install apps from trusted sources, such as the pre-installed app stores. Check the permissions of the apps you have installed both during installation and regularly thereafter. Only allow apps access to sensitive data such as location, contacts and camera if they really need this information.
