How to install Opera Mini 78.0.0 APK

Uninstall the current version — go to Settings → Apps → Opera Mini → Uninstall. This is needed because Android won't allow installing an older version over a newer one without uninstalling first.
Enable installation from unknown sources — in Android Settings, allow APK installation from your browser. On Android 8+, this is done per-app.
Download APK file 78.0.0 — tap the "Download APK" button above. The file (16 MB) will start downloading to your Downloads folder.
Open the downloaded file — find the APK in your file manager or notification shade and tap it.
Confirm installation — Android will show requested permissions. Review them and tap "Install".
Open Opera Mini — after installation, tap "Open" and sign into your account. Archive version 78.0.0 is ready to use.

When to use Opera Mini 78.0.0
Archive version 78.0.0 of Opera Mini is useful in the following situations:
Weak device
If your phone has 2-3 GB RAM or processor older than Snapdragon 6 series, new versions may lag. 78.0.0 is lighter and runs smoother.
Old Android version
New version requires Android 10+, but you have Android 8 or 9. Archive version 78.0.0 still supports older OS versions.
Familiar interface
Developers redesigned the UI and you find it unfamiliar. Version 78.0.0 keeps the old interface you've grown accustomed to over years.
Removed feature
A feature you constantly used was removed in the new version. Rolling back to 78.0.0 restores the functionality.
Frequently Asked Questions about Opera Mini 78.0.0
Can I roll back from a newer version to 78.0.0?
Yes, but you'll need to uninstall the current version of Opera Mini before installing the archive. Android won't allow installing an older version over a newer one. After installing 78.0.0, it's recommended to disable auto-updates in the Play Store.
Will my data be preserved?
When you uninstall an app, local data is usually wiped. If your Opera Mini account uses cloud sync, data will be restored when you sign in to the new version. Backup is recommended before rolling back.
Why is 78.0.0 better for my device?
Each new version adds features and gets heavier than the previous. If you noticed that after the update Opera Mini started lagging, draining battery or freezing — rolling back to stable 78.0.0 often solves the problem without buying a new device.
