How to install the Kid-Safe Experience on an existing Samsung device

For customers in New Zealand and Australia, Safe Surfer supports installing the Kid-Safe Experience on used Samsung smartphones and tablets. We recommend purchasing a brand new device in accordance with the purchasing guide, but if you would like to install the Kid-Safe Experience on a used device, there are a few steps you'll need to take:

1. On the device that you would like to use, open the Settings app > About [phone/tablet] > Software information. You'll need to make sure that the device is running at least Android 11, along with having a listing that mentions "Knox version". (If it's running Android 10 or older, or doesn't mention Knox, unfortunately it is not supported, but you can still protect the device with our normal Android app.) Once you've confirmed compatiblity, return to the About [phone/tablet] menu.
2. Visit the Device Compatibility page for Samsung Knox. To verify compatibility, you'll need to match the model name of the device as displayed on the About [phone/tablet] menu (for example, "SM-S911B/DS", where "SM-S911B" is the important part) with a listing on the compatibility page. Once you've found the listing for your device on the compatibility page, the third field must mention "Android - Secured by Knox". (If it mentions anything else, unfortunately it is not supported, but you can still protect the device with our normal Android app.)
3. Once you've confirmed the above, you can take a photo of the serial number on the About [phone/tablet] menu, back up your files and app data, and then factory reset the device (Settings app > General management > Reset > Factory data reset, with its following prompts). Once the device reaches the Welcome screen, you can turn it off.
4. Visit the Activate page to send us an activation request for the device. If you're activating more than one device, you'll need to send a request for each individual device. Activation requests take us approximately 1–3 working days to process. Please wait for an email from us (which will contain the setup guide) before unboxing and turning on the device(s).
