### Signal Messenger
(How to Get the APK for DeGoogled Phones)

Signal is a great open-source messenger app that is available across all platforms. Linux, Android, DeGoogled Andriod, MS, Apple, Linux phones, and iPhones.

Signal end-to-end encryption is the current standard that many chat apps follow and use, such as WhatsApp.

Unfortunately, Signal won't use F-Droid because they say the F-Droid app store is vulnerable to exploits. So if you want to install Signal on Android w/out using the Google Play Store, they offer an APK, and a signature key, but they don't make the APK easy to find.

So here's the link to the APK:

Signal Messenger APK

This 👉 post shows you how to verify the Signal APK signing certificate.

This 👉 post (video) shows you how to install Signal on Linux using an Ubuntu/Mint PPA.

### Signal - Verify APK

1. Download the Signal APK from the link below to your Linux computer by clicking the "Download" button and saving it to a directory, such as the "Download" directory in your "home" directory:

Signal APK for Android/DeGoogled Phones

2. Install apksigner onto Linux. On Ubuntu based distros (Mint, Ubuntu, etc.), type this into a terminal:

sudo apt install apksigner

3. Open a terminal and go to the directory where you downloaded the Signal APK into, & type this into a terminal:
(replace this apk filename with your apk filename)

apksigner verify --print-certs --min-sdk-version 25 Signal-Android-website-prod-universal-release-6.6.3.apk

4. You can then verify the SHA256 fingerprint on the website with the SHA256 fingerprint from the output

5. Transfer the APK to your phone & install. You can transfer using a USB cable, KDE Connect, or by using SFTP and Material Files.

>Notes
"-min-sdk-version 25" means verify the signatures work on Android API versions 7.1 & higher. This will eliminate warnings for any unsupported version below 7.1
