Samsung Galaxy S26 Ultra VS OnePlus 15
Verdict DROP IT DROP IT
The Reality 9to5Google's hands-on and LTT Labs' independent lab testing confirmed the Privacy Display effect is real and functional at narrowing the viewing cone. But TechRadar reported a wave of real user complaints that the effect makes the screen genuinely nauseating to look at even for the primary user, not just people at an angle — a side effect none of the marketing mentioned. Wired's full review and The Register's iFixit-based teardown also flagged Samsung's repairability regressing again this generation. Less than a year after the OnePlus 15 launched, Bloomberg reported that OnePlus is ceasing consumer phone operations in the US and Europe entirely — a major business retreat, not a rumor. That means anyone buying the OnePlus 15 in those markets is buying into a brand that has already announced it's stepping away from after-sales support, software updates, and future models there.
SHORT ANSWER
Samsung Galaxy S26 Ultra: The Galaxy S26 Ultra's Privacy Display genuinely narrows viewing angles as advertised, but real users report it causes nausea during normal use — a tradeoff Samsung didn't disclose.
OnePlus 15: OnePlus confirmed it is ceasing operations in the US and Europe just months after the OnePlus 15 launched there — a real business risk for anyone buying it in those markets, regardless of the hardware's specs.
