How to install German for Beginners: LinDuo v5.31.1 on Android 5.1 Lollipop+
Takes about 2 minutes. You'll need roughly 104.9 MB of free storage.
- Grab com.lin.duo.hd.german_200090.apk — hit the Download button above (104.9 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 b7c6361c852c4b98…. Any difference means the file is corrupted or tampered — delete and re-download.
- Open the APK — tap the download notification, or find com.lin.duo.hd.german_200090.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 O=www.Lin-Duo.com. 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 German for Beginners: LinDuo — tap Open on the install screen, or find the German for Beginners: LinDuo icon in your app drawer (this build targets arm64-v8a devices).
Common install errors for German for Beginners: LinDuo
- "App not installed" — usually means an older or differently-signed version is already on your device. Uninstall it first, then retry. Your data may be lost unless you back it up.
