After you have installed the TikTok 18 app, it's important to turn on the "unknown sources" option. Once you've enabled this setting, the app will automatically detect the latest APK and update itself. Then, you can activate the "auto-update" option. This way, you'll get the latest version of the app without any hassles. If you're concerned about downloading malware, try using an uninstaller first.

While TikTok is a fun app for Android users, you should be sure to check the age requirements first. The app is intended for adults, so children should not use it. While it's free, there are some features that can be controversial. The app features sexual content and other adult content, and it doesn't allow for underage users. There's also some content that is aimed at children. TikTok 18+ offers a safe and fun experience for those who want to express themselves creatively.
