  1. Open the file on your phone and allow the install when Android asks.

  3. To go back, press Home and pick your old launcher again. Folio changes nothing else on your phone.

Check what you downloaded

Two different things are worth checking, and they answer different questions. The file checksumproves you have the exact bytes that were uploaded. The signing certificate proves the app was built by whoever holds Folio's key, and it is what makes future updates safe.

The signing certificate

This one never changes. Every Folio release, past and future, is signed with the same key. If it ever differs, something is wrong and you should not install it.

keytool -printcert -jarfile Folio-0.6.6.apk

keytool comes with any JDK. With Android's build tools you can useapksigner verify --print-certs Folio-0.6.6.apk instead. Either prints the same SHA-256 digest as above.

Both values are published with every release, onthe release page as SHA256SUMS.txt andsigning-certificate.txt, so the site and GitHub can be compared against each other.

Warnings you may see

"Uncommon download"

Chrome shows this for files it has not seen before. Every new Folio release starts that way and it clears by itself as more people download it. It is not a finding about the file.

Play Protect asks to scan the app

Android checks apps installed outside the Play Store. Letting it scan is fine. Folio asks for no permission it does not explain, and every one is listed inPERMISSIONS.md with what happens if you say no.

An update will not install

A release APK cannot install over a build you compiled yourself, because the signing keys differ. Uninstall the one you built first, or keep using it.
