Duplex IPTV is a new application that works on Android devices and smart TVs. It is a good alternative to SMARTIPTV since this app is paid and recently had issues with Samsung smart TVs.
If you do not have a m3u list provider to watch IPTV channels, you can visit the site of a service that offers Latin channels by clicking here.
For those using an Android device, go to the App Store and search for Duplex IPTV.
At the end of the installation, open the application and this screen will appear.
Now we need to go to the site that appears on the screen at www.Edit.Duplexplay.com
And enter the two digits that appear on the screen: Device ID and Device Key.
