Devices such as these only receive security updates for a certain period of time, generally three to five years. Take note of whether your device is still receiving security updates (it may automatically inform you when time expires), and don’t use it beyond its intended lifespan.

Phone and tablet software should be vetted by approval teams to ensure their quality and security. Such processes are routine on official app stores, but cannot be assured with third-party sources. Accordingly, steer clear of unofficial storefronts or sideloaded apps from websites.

It’s not as popular as it was in the early 2010s, but jailbreaking (or rooting) a mobile device is still a risky practice. It removes many built-in protections and allows the installation of unapproved applications. Stick with the standard OS and keep it updated.
