Android OTA Updater
We recommend to install the latest Android OTA Updater app from KB24511
OTA (Over the Air) Update
The most common way to update your handheld device is with the built-in OTA system.
To look for and install updates, open: Settings > About tablet/device > Check for system updates
This screen shows the currently installed version as well as the last time the system did check for an update.
If you don't want to install the update over OTA or if you want to directly install an update file, follow these steps.
- Download the latest update zip file:
Algiz RT7 Android 5 KB19457
Algiz RT7 Android 6 KB23186
Nautiz X2 Android 5 KB20458
Nautiz X2 Android 6 KB22690
Nautiz X2 Android 7 KB24551
Nautiz X9 Android 7 KB24157
Note: It's not possible to install Android 5 on a unit with Android 6 or install Android 6 on a unit with Android 5 without sending in the unit to service.
- Place the update zip file on the unit. You can either copy it to the internal storage, sd card or use an USB memory drive (USB memory drive is for Algiz RT7)
- Open Settings > About tablet/device > Check for system updates
- Tap the SD card icon in the top right corner and confirm the dialog
- Navigate to the update zip file and press OK
- Confirm the selection and wait for the installation to finish. The device will restart on its own once the update is done.
