Samsung Max VPN is provided by Samsung itself obviously it's safe and you can use . but you can use other vpn apps on your Samsung device as well no problems. one thing do remember though every VPN apps available on play store can't be safe ( not every apps obviously ) . any random third party vpn app may be a kind of tracker of your device information specially in these days !! Samsung Max VPN is surely safe in that way 👍🏻

The Samsung Max app encrypts data when it is sent through a public Wi-Fi network. Likewise, there are features such as tracker blocking and DNS masking to offer a secured Web browsing experience. You can view privacy reports to see how the app adds security to other apps and network connections.
