The Samsung Galaxy Z TriFold, unveiled last December and already discontinued in multiple markets, is 3.9-4.2mm thin when unfolded and 12mm thick when folded. According to a new rumor, the second-gen TriFold, which might be called Galaxy Z TriFold 2, could be thinner than the original TriFold.

The slimmer profile of the Galaxy Z TriFold 2 would be courtesy of a new hinge mechanism being developed by Samsung. However, the TriFold 2 won’t be the only foldable that will benefit from it, as the source claims that a version of this new hinge with technical adjustments will be used for other single-folding Samsung smartphones.

It’s unclear whether the single-folding Galaxy smartphones expected in a few months will come with this new hinge, or whether the ones launching next year will, since the TriFold 2 itself is rumored to arrive in mid-2027, and we doubt Samsung will use the new hinge mechanism for single-folding smartphones before the second-gen TriFold.
