According to a Korean source, Samsung will dress up the future Galaxy S24 Ultra in titanium. For now, only this model from the S24 series would be made of titanium, contrary to earlier rumors.
Titanium is not only a somewhat tricky material to work with, but it is also quite pricey. Samsung would, therefore, first want to see how the public reacts to this new material choice. The S24 Ultra seems like the ideal candidate to test that theory out. Its starting price is already relatively high.
Rumors that Samsung, like Apple, would equip its devices in titanium have been going around for some time. As such, it seems to be the trend for 2024. Previously, the frames of phones were made primarily of aluminum alloy. Titanium is stronger but considerably more expensive. Its biggest plus is its appearance, especially when brushed.
No significantly lower weight
Apple achieved a substantial weight reduction with the iPhone 15 Pro and Pro Max, but that was because those models previously had stainless steel frames. That's considerably heavier than aluminum. Samsung uses aluminum for the S23 Ultra, so we don't expect a substantially lower weight there.
