A potential problem with the Galaxy S26 launch may be averted by a specific solution for Samsung.

Samsung needs a two-phone Galaxy S26 lineup and a wildcard entry.
Samsung's Galaxy S26 series may be better with fewer models.
Samsung might dilute its lineup by offering two less impressive models. Most smartphone companies want at least three models in their high-end lineups to appeal to more consumers. However, a fourth model might not be beneficial for Samsung.
It may be best for Samsung to scrap or postpone the Galaxy S26 Edge and Plus. The company could instead introduce the Galaxy TriFold as part of the Galaxy S26 lineup.
Smartphone companies often borrow ideas from each other. While Samsung is taking cues from Apple, it needs to copy in a smarter way. Apple tends to wait and study features before implementing them. Playing it safe can be a good idea.
Apple is rumored to release its first foldable smartphone with the iPhone 18. Samsung could go further by introducing a new category with the Galaxy S26. The Galaxy TriFold may be unveiled later this month, but its release date is unknown.
It seems Samsung might not be ready to ship the TriFold model yet. Delaying the announcement and launching it with the Galaxy S26 could be a better idea.
Samsung needs to be bolder and make a statement. The Galaxy S26 lineup would be better with two well-executed models instead of the poorly executed Galaxy S26 Plus and Edge. Including the Galaxy TriFold would show that it's more than a concept device. It could be someone's next phone, like the Galaxy S26 and Ultra.
The Galaxy S26 series could benefit from the attention that the first mainstream trifold device would bring. It's a risk, but that was Samsung's approach before it lost its unique identity.
