What's new in v1.16
Release 1.16 fixes some autofocus problems that caused traps on some devices. If this version does not recognize diagrams then in settings uncheck the continuous video autofocus flag.
Release 1.15 allows recognition in both portrait and landscape mode, and deals correctly with orientation changes. If you don't want automatic screen rotation just disable it on the device, or follow the instructions above to reinstall ChessOcr 1.13 (which does not autorotate) and disable updating of the app.

How to install ChessOcr OCR Chess Diagrams v1.16 on Android API 11+
Takes about 2 minutes. You'll need roughly 4.8 MB of free storage.
- Grab com.kgroth.chessocr_17.apk — hit the Download button above (4.8 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 decbb31f09c65c2f…. Any difference means the file is corrupted or tampered — delete and re-download.
- Open the APK — tap the download notification, or find com.kgroth.chessocr_17.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=Gerhard Roth, L=Ottawa, ST=Ontario, C=CA. 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 ChessOcr OCR Chess Diagrams — tap Open on the install screen, or find the ChessOcr OCR Chess Diagrams icon in your app drawer (this build targets armeabi/armeabi-v7a devices).
Common install errors for ChessOcr OCR Chess Diagrams
- "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.
- "Parse error" — the APK is for a newer Android than yours. This version needs Android API 11 or later. Pick an older build from the versions list below.
- "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/armeabi-v7a native code. Devices with a different CPU will reject it.
