Better screen mirroring
About this app
SecondScreen is an application designed for power users that frequently connect their Android devices to external displays. It works with your existing screen mirroring solution to give you the best experience possible. With SecondScreen, you can change your device's resolution and density to fit your TV or monitor, enable always-on desktop mode in Chrome, and even turn your device's backlight off, among several other features.
This app requires elevated permissions, granted via root access or adb shell commands. The app will do nothing if you do not have a rooted device or access to adb.

How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be com.farmerbb.secondscreen.free is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 2.9.3 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall SecondScreen first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of SecondScreen, and a listing is removed when the evidence for it stops holding up.

Permissions Required
What each permission lets SecondScreen do. A highlighted one is worth a second look — not necessarily wrong, just worth asking whether this app needs it.
Previous Versions
The signing certificate fingerprint for this release is on record, so a build that does not match it did not come from this publisher.
