Recommended free space
Allow at least 500 MB free as a safe baseline. If the page shows an exact APK size, plan for that size plus a 300 MB buffer to allow unpacking and temporary files during installation.
Wi‑Fi vs mobile data
Use a reliable Wi‑Fi connection for large downloads. If using mobile data, ensure signal is stable and you have enough data credit; interrupted mobile downloads are more likely to corrupt APK files.
Handling stopped or corrupted downloads
If a download stops or the APK won’t open: 1) clear your browser cache and retry (Browser Settings > Clear browsing data); 2) delete any partial .apk file from your Downloads folder before re-downloading; 3) try a different browser if the issue persists; 4) download over Wi‑Fi rather than mobile data; 5) if you still see errors, contact Support with the exact error text and the file size shown in your Downloads list.
Temporary install permissions
On Android 8+ grant permission per app: when prompted choose the app (browser or file manager) and toggle Allow from this source. Remember to disable the permission after installation to keep settings strict.
