5 min · essential
Why this matters. Android gets security fixes two ways: system updates from your phone's maker and Google Play system updates from Google. Play Protect is Android's built-in malware scanner: it checks apps when you install them and scans your phone regularly. Phones stop getting updates after a few years, so check how long yours is supported.
