Open the channel while it's playing, or long-press it in the guide, and look for a star, heart or "add to favorites" icon. That single tap writes the channel into a saved list stored on your device. Some apps use the word favorites, others use follow, watchlist or bookmark. They all do the same job: they don't change your playlist, they just give you a shortcut view of it so the channel you follow tonight is one tap away tomorrow instead of buried in a full list of 50,000-plus entries.

Most apps let you drag followed channels into a custom order, or split them into your own groups, like News or Sports, separate from the provider's default categories. This matters more than it sounds like it should: once a followed list passes a few dozen channels, an unsorted one is almost as slow to scan as the full guide was. Renaming groups and reordering favorites happens entirely inside the app's settings menu, and it's saved locally, so it survives app updates but usually not a full uninstall. If you switch to a new phone or a new streaming box, expect to rebuild the order from scratch rather than find it waiting for you.

Yes, but it's a separate step from following. Your provider gives you one playlist link, usually through an M3U file or an Xtream Codes login with a server address, username and password. You load that once when you first set up the app, and it populates the full channel list, often tens of thousands of entries. Following individual channels afterward doesn't add or remove anything from that playlist. It just marks a subset of it as the channels you want quick access to, which is a display choice, not a second subscription or a second login.

Because IPTV doesn't tune into broadcast frequencies, there's nothing to scan for. A traditional antenna or cable box scans the airwaves or a cable line and builds a channel list from whatever signals it finds. An IPTV app instead reads a playlist file your provider already built and hands to you at setup. Automatic scanning shows up often as a feature request in player app communities, which tells you it doesn't exist yet in the tools people use. Following a channel works with the list you were given, not a list the app discovers on its own.

It can, if you're combining program guide data from more than one place. Some setups pull the channel list from an M3U file and the schedule data, the electronic program guide showing what's on now and next, from a separate Xtream Codes source. That combination is a real, workable configuration, but it's a manual step you set up once, not something the app does automatically. If a followed channel shows no program info while others do, mismatched EPG mapping between those two sources is the most common reason, not a broken follow list.
