The app checks for new versions by itself, when you open it and when you come back to it, at most every 6 hours. It needs internet for that.
When there is a new version
- “There is a new version of Yammbo POS” appears with the number. People with the Settings permission see it.
- Tap “Update”. You will see “Downloading the update” with the percentage.
- The first time, Android asks for permission: “Allow Yammbo POS to install updates”. Tap “Open settings”, turn on the permission and come back. The installation continues by itself.
- Confirm the installation on the Android screen.
“Later” postpones it for 24 hours. Your data is not touched when updating.
Check by hand
Open Settings > This device > Updates. There you see the installed version and the “Check for updates” button. If you already have it, it says “You have the latest version”.
If it fails
If you see “The update failed”, tap “Download from the browser”: the installation file downloads and you open it by hand. You can also download it with “Download Yammbo POS” on pos.yammbo.com: it is always the latest version. Install it over the one you have, without uninstalling.
Do not uninstall
Uninstalling the app erases the tablet’s data. To update, always install over it.
Multiple tablets
If you have multiple tablets in the location, update all of them the same day. Tablets with different versions stop syncing with each other until they all have the same one.
