For the companies building frontier models, the smallest improvement in performance could equate to huge gaps in model benchmarks and rankings, which are closely followed by developers and translate directly to usage, revenue, and valuation.
The Phone 4a Pro has its own take on the Glyph Matrix, composed of 137 mini-LEDs. That’s fewer LEDs than the Nothing Phone 3, but they are 100 percent brighter at around 3000 nits. It supports pretty much all the Glyph toys we enjoyed on last year’s Nothing flagship, although the 4a Pro lacks a dedicated Glyph Button, which is a shame. This means in order to hop between toys and modes, you’ll have to dig into Glyph settings inside the settings menu – not the existing Glyph menu – in order to flit between them. Honestly, may make me less likely to play around with the Glyph, but I’ll have to see after further testing. It’s a little odd when there’s a circular metal detail on the lower left corner that looks like it could have been a Glyph button. Ah well.
