Two ways to install on Android:

1. Browser download (APK): Tap Android · Browser download, then open the downloaded APK and follow the prompts (allow install from unknown sources if asked).
2. Google Play: Tap Open Google Play for one-tap install with automatic updates.

Tips for Chinese-brand phones

Phones sold in mainland China ship with built-in “app safety scan”, “pure mode”, and “store certification” guards that often block APKs not published on a local store. Below is brand-specific guidance—exact wording differs by OS version, but the idea is the same.

Huawei / Honor (HarmonyOS / EMUI / MagicOS)

• When you see “Failed app market safety check”, tap More → Continue installation.
• If it loops or freezes, turn off Wi-Fi and mobile data, then reopen the APK to install.
• Or temporarily turn off Settings → System & updates → Pure mode, then reinstall and turn it back on.

Xiaomi / Redmi / POCO (MIUI / HyperOS)

• The prompt says “App failed certification”—tap the Settings / More icon at the top right (or Continue installation inside the dialog).
• In “App installation service”, turn off Security check before install, or choose Allow this install only.

OPPO / OnePlus / realme (ColorOS)

• Choose Continue installation in the prompt.
• If blocked: Settings → Additional settings → Manage app install sources / Install unknown apps → enable for your browser or file manager.

vivo / iQOO (OriginOS / FunTouch OS)

• When prompted about risk, choose I understand the risk, continue installing.
• If it still fails: Settings → More settings → Permission manager → Install apps → grant permission.

Samsung (One UI)

• Settings → Biometrics and security → Install unknown apps → enable “Allow from this source” for your browser or file manager.

Other situations

• Browser blocks the download with “this file may be harmful”: choose Keep / Download anyway.
• File manager says “Can’t install”: use the system’s built-in file manager to open the APK.
• Still failing: use Google Play instead.
