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 on Android 3.0+
You'll need about 9.6 MB of free space.
- Download the APK — tap Download APK above (4.8 MB). Chrome shows “File might be harmful” for every APK file; choose Download anyway only if you trust this file.
- Open the file — tap the download notification, or open Files › Downloads and tap com-kgroth-chessocr-17-10868585-decbb31f09c65c2fd39a4eb4be1cc256.apk.
- Allow the install (first time only) — Android 8 and later asks for permission the first time an app opens an APK: tap Settings in the prompt, turn on Allow from this source, then go back. Manual path: Settings › Apps › Special app access › Install unknown apps (on Samsung: Settings › Apps › ⋮ › Special access). On Android 7 and older: Settings › Security › Unknown sources.
- Check the file (optional) — the MD5 of the downloaded file should be decbb31f09c65c2fd39a4eb4be1cc256. If it differs, the file is damaged or was changed: delete it and download again.
- Tap Install — Android asks “Do you want to install this app?”. If Google Play Protect shows a warning, read it before you continue: the source store rated this file Trusted, but only install apps from sources you trust. If an earlier version is installed, this one only installs as an update when it is signed with the same certificate (SHA-1 shown above).
- Open ChessOcr OCR Chess Diagrams — tap Open on the install screen, or find it in your app drawer.
Common install problems
- “App not installed” — a version signed with a different certificate, or a newer version, is already installed (Android doesn't allow downgrades). Uninstall it first; back up your data, because uninstalling deletes it.
- “There was a problem parsing the package” — the file is incomplete, or your Android is too old (this version needs Android 3.0+). Download it again, or pick an older version.
- “App not compatible with your device” — this build contains native code for ARM (legacy), ARM 32-bit only. Devices with other processors can't install it.
- Blocked by Play Protect — Play Protect checks apps from outside the Play Store. Only continue if you trust the source.
