The ROG Phone 3 looks very similar to the ROG Phone 2, And you can see that as well as the design is similar, the size is almost exactly the same. The ROG Phone 3 is just slightly thicker. And that is partly because it’s got more of a camera bump because of the new cameras. In terms of size, both are actually the same almost that’s the reason the accessories that we have for the ROG phone 2 fit even on the ROG 3. The ROG phone 3 screen is a lot brighter also in terms of refresh rate this has 144 Hz compares to 120Hz in ROG 2, and even the touch response is higher on the ROG phone 3.
There aren’t as many lines as we’ve got on the ROG Phone 2. And the aerodynamic cooling section has also been updated with this more minimal design. There’s of course the RGB ROG logo, which you can customize. And it looks cool.
