Troubleshooting

Start with what went wrong.

Short answers live in the app and work offline. These guides add the device settings, tested hardware and recovery steps that do not belong inside an APK.

Tested hardware

Known equipment, not required equipment.

These are the devices used during development and hands-on testing. Listing them records what we actually verified; it is not a sponsorship, certification, or claim that other compatible hardware will not work.

Used to test the tablet layout, camera scanning, hardware-keyboard behavior, backups, and routine inventory workflows.
