For Android, you can download the app from the Google Play Store or use the APK files provided in the Releases section.

If you choose to install the APK manually, we recommend verifying its signature to ensure its authenticity. Vexl signs the APK with the following certificate fingerprints:

SHA-256: 84a7fbcd54a4ca60e52b25311862ce4715d50a62c203760dbcb91aefe8eb20d4

1. Download the APK file.

2. Run the following command to print its signing certificate fingerprints:

   apksigner verify --print-certs your-apk-file.apk

3. Confirm that the fingerprints match the values listed above.

If the fingerprints do not match, do not install the APK and contact us to report the issue.
