How to install KOSMOS Helper App v3.5.17 on Android 8.0 Oreo+
Takes about 2 minutes. You'll need roughly 110.2 MB of free storage.
- Grab com.kosmos.tutorial_3051701.apk — hit the Download button above (110.2 MB). If your browser warns about APK files, choose Keep or Download anyway — that warning fires on every APK, not just this one.
- Trust your browser to install — on Android 8+ go to Settings → Apps → Special access → Install unknown apps, pick the app you downloaded with (Chrome, Firefox, Files, etc.), and flip Allow from this source. On older Android, toggle Unknown sources under Security.
- (Optional) Verify the file — compute the MD5 of the downloaded APK and make sure it matches 816cf5ee627bf063…. Any difference means the file is corrupted or tampered — delete and re-download.
- Open the APK — tap the download notification, or find com.kosmos.tutorial_3051701.apk in your Files app under Downloads, then tap it. Android's package installer will appear.
- Check the signer — the install screen will name the publisher. For this build it should read CN=Hendrik Peeters, OU=Producer, O=Tivola Publishing GmbH, L="D-22769 Hamburg. If it doesn't match, cancel — you have the wrong file.
- Review permissions & tap Install — scroll the permission list, then confirm. If Play Protect flags it, tap Install anyway (this APK was scanned as TRUSTED).
- Done — open KOSMOS Helper App — tap Open on the install screen, or find the KOSMOS Helper App icon in your app drawer (this build targets armeabi-v7a/arm64-v8a devices).

- "There was a problem parsing the package" — the download was interrupted. Delete the file and re-download over Wi-Fi.
- Works on one phone but not another — this build ships armeabi-v7a/arm64-v8a native code. Devices with a different CPU will reject it.
