How to Download and Install Demus APK on Android – Step-by-Step Guide (2026)
If you have never installed an APK file on your Android phone before, the whole process can feel a little confusing at first. In this guide I am going to walk you through every single step from enabling the right permission on your phone, to hitting play on your first song. I have done this myself on multiple Android devices, so everything you see here is tested and working as of 2026.
Before we start, if you want to know more about what this app actually offers, check out our complete Demus APK review on the homepage first. It covers all the features, pros, cons, and why millions of Android users prefer it over paid streaming services.
What You Need Before Installing
Nothing complicated here. Just make sure you have these three things ready:
- Your Android phone must be running Android 5.0 or higher. To check, go to Settings → About Phone → Android Version.
- You need a stable internet connection for the download. WiFi is preferred but mobile data works fine too.
- You need about 30–40 MB of free storage space on your phone.
Step 1 — Go to the Official Demus APK Download Page
This is the most important step and I want to be very clear about it always download Demus APK from the official source only. Go directly to getdemusapp.com and click the Download button. The file is always kept updated here, so you will always get the latest stable version. We actually have a whole article on is Demus app safe if you want to understand exactly what is inside the APK file before you install it — worth a quick read.
Once you tap the download button, the APK file will save to your phone’s Downloads folder automatically.
Step 2 — Enable “Install from Unknown Sources”
Here is the part that confuses most people. Android does not allow apps from outside the Play Store to install by default. You need to give permission manually. This is completely normal and safe you are just telling your phone to trust this one file. How you do this depends on your Android version:
Android 8.0 and above (most phones today): When you tap the APK file to install it, Android will automatically ask you which app you want to use to open it — usually your file manager or browser. It will then show a prompt saying “For your phone’s security, your phone is not allowed to install unknown apps from this source.” Tap Settings on that prompt, then toggle on “Allow from this source.” Go back and the installation will continue.
Android 7.0 and below: Go to Settings → Security → scroll down and find “Unknown Sources” → toggle it ON. You will see a warning — tap OK to confirm.
Once you have done this once, you will not need to do it again for future updates.
Step 3 — Open the Downloaded APK File
Open your phone’s file manager app. If you do not have one, your phone’s built-in Files app works perfectly. Navigate to the Downloads folder and you will see a file named something like Demus_1.6.8_getdemusapp.com.apk.
Tap it once. Android will ask how you want to open it — select “Package Installer” or just tap Install. Do not tap anything else or it might try to open the file in the wrong app.
Step 4 — Tap Install and Wait
After you tap Install, you will see Android’s standard app permission screen. Demus will ask for access to your storage (to save downloaded songs) and possibly your microphone (for voice search). These are normal permissions for any music app.
Tap Install and wait about 10 to 20 seconds. The installation bar will fill up and then you will see the “App Installed” confirmation screen.
Do not close the screen or press the back button during installation — just let it finish on its own.
Step 5 — Open Demus and Start Listening
Tap “Open” on the installation screen and Demus will launch for the first time. You do not need to create an account or log in. The app opens straight to the music library and you can start searching for songs immediately.
For the best experience, I recommend letting the app load fully for about 10 seconds on first launch before searching for anything. This gives it time to set up its local database properly.
How to Update Demus APK in the Future
Updating is exactly the same process as installing. When a new version is available, come back to getdemusapp.com, download the new APK file, and install it over the existing app. You do not need to uninstall the old version first Android handles the update automatically when you install a newer version over an older one.

We have a full troubleshooting guide that covers every possible issue — How to Fix Demus APK Not Working — with 7 tested solutions. That guide will solve 99% of problems you might run into.
