I finished my review of last year’s Nothing Phone 3 in a weird place. As much as I like Nothing OS and much of what Nothing did with its trio of cameras, I struggled to get behind the revamped design and felt like the Glyph Matrix was dead on arrival. And yes, Nothing has worked hard since then to at least make the latter more useful, but you just can’t fix a flawed design.So, you better believe I’m thrilled with the first look at the new Nothing Phone 4a. It’s both a step forward and a throwback to a better era in terms of design, and I think it fixes everything that was wrong with the Phone 3. Here’s why.
