Asus has made some significant improvements to the ROG phone, which first appeared on the scene in 2018: Instead of 90 Hz, we now have 120, instead of 8 GB of RAM, there is now 12, and there is, of course, a brand-new SoC on board. We had a chance to play a few games on it, and when it came time to give it back, we did so rather reluctantly. However, if you plan on using it for anything other than gaming such as making phone calls, surfing the web, emailing etc., then its weight of 240 g might prove to be not very easy to overlook.
