According to the same source, the Galaxy A37 has a 6.7-inch FHD+ AMOLED screen with a 120Hz refresh rate, the Exynos 1480 SoC at the helm, a 50MP main camera using a 1/1.56" type sensor, an 8MP ultrawide, a 5MP macro camera, a 12MP selfie camera, and a 5,000 mAh battery with support for 45W wired charging. The phone will be IP67 rated for dust and water resistance.
The flashiest comparison revolves around the Glyph interface - it's a simple Glyph bar on the non-Pro and a full-on circular dot matrix display on the Pro. Getting technical for a bit, the Pro has 137 LEDs, while the regular has just 63. As you can imagine, you can do all sorts of clever stuff with the Glyph Matrix on the Nothing Phone (4a) Pro - animating your timer, different callers, you can even use it as a selfie display for the main camera.
The Galaxy A57 is tipped to sport a 6.6-inch AMOLED screen. It is said to have an Exynos 1680 SoC, a triple rear camera setup, and a 5,000mAh battery. The newly leaked renders show the Galaxy A57 in Charcoal, Icyblue, Lilac, and Navy color options.
