Whereas filming a brand-new Volvo EX90 together with his iPhone 16 Pro Max, the cellphone’s digicam caught extra than simply the glossy SUV.

One other Reddit consumer reported that their Samsung Galaxy S24 Extremely developed unusual traces after attending a laser-filled occasion. The patterns appeared in pictures and movies, significantly at sure zoom ranges.
Specialists say occasion lasers are typically eye-safe however can simply destroy digicam sensors if the beam hits straight. The Worldwide Laser Show Affiliation has lengthy warned about this particular danger.
