All three are official Google components installed by Android itself and updated through the Play Store. They aren’t viruses. Here’s what each one does.

Android System WebView
This is the component that displays web pages inside other apps: when you open a link inside Instagram, a banking app or a news app without leaving the app, WebView is what draws the page.
- Keep it installed and up to date. Many apps stop working or close on their own if WebView is outdated or disabled.
- If an app starts closing on its own after a WebView update, also update Google Chrome and restart your phone.
Android System SafetyCore
This is a Google service that classifies images on the phone itself, without sending them to the internet. It’s used, for example, by the sensitive content warnings in Google Messages, which blur images containing nudity and ask before showing them.
- According to Google, the analysis happens on the device, and no images or results are sent to Google’s servers.
- Sensitive content warnings can be turned on or off in Google Messages settings.
- Can you uninstall it? On many devices you can uninstall or disable it from the app list. But it may come back with updates and, without it, the features that depend on it stop working.
Android System Key Verifier
It’s used to confirm you’re talking to the right person in apps with end-to-end encryption, such as Google Messages. Both phones display a QR code; by scanning it, you confirm that the encryption keys really belong to your contact, and not to a scammer who cloned their number (for example, after a SIM swap).
- It works on Android 10 or newer.
- It only does something if you use contact verification. It sits idle the rest of the time.
How to tell if an app with “Android System” in its name is legitimate
- Open the Play Store, tap the app and check that the developer is Google LLC.
- Legitimate system apps never ask to be installed from a link, text message or WhatsApp.
- If a “system” app shows ads or asks for accessibility permissions to “protect” you, it may be malware. See how to spot phishing.
