Vita's screen is very nice at doing pure black at the native resolution of 544p but the thing is, a ton of Vita games are sub native res and in those cases you get a crazy bleed effect from some areas, Killzone is fairly nasty looking at times when it comes to dark area's  same is true of a games on the Vita being upscaled from things like the PSone, non native just doesn't work great with that screen, unless you mean the LCD version in the Vita slim edition, that's better in general than the originals but loses out on the very nice pure blacks which the OLED screen offers.

Yeah I was really only talking about the advantage of OLED, my bad. 

Who is this marketing aimed at??
As far as I can tell the only major country that would buy gaming phones is China, a market where they already have Nintendo beat.
I cant see this working in the US or EU really, the interest in such a product in those regions is pretty low. Too much of a niche product to have a big impact.
And then theres Japan, who sure love them some mobile gaming but the games that dominate are games specifically made for mobile and usually one hand use too. Not to mention Japan is iPhone country.

So? Nobody cares about better specs unless they can back it up with a competitive price and compelling library. Hardware makers still continuously fail to realize that specs are not what sell consoles, games and attractive hardware at a good price do. That's why the PS4 base still regularly outsells the Pro, and why the Switch is still selling on par with, at times outselling the PS4. Huawei can say their phone has all these technical advantages all they want. But's it's still a $900 Android device with half of a controller, and all the limitations and jank that Android comes with. Switch may be technologically inferior, but's it's a better designed device in just about every way from controls, to optimization, and efficiency. 

Did you even bother look it up?

PUBG, Fortnite and Minecraft aren't exactly "nothing" though.

The device uses Vapor Chamber cooling, similar to what is found in high-end PC video cards and the Xbox One X.
- Granted it is unlikely to feature a fan to assist, it's still impressive.

With that in mind... A throttled Kirin 980 SoC will still beat the permanently-throttled old 2015~ era Tegra X1 chip anyway. So meh.

lol I wish I had that much self-esteem

The receipt when you buy it counts as an achievement, right?

And two of those are all ready on the Switch. Point is, It doesn't matter if it has better specs or not, Switch versions will still look and run better in most cases as it doesn't have to deal with an Android overhead, or have to scale to the lowest common denominator. Thing with phone games is that they always have to be able to run well on the least powerful phones available at any given moment, which means that games on Hwauwei's device will never get to use its power because the games still have to run on Android devices that are even weaker than the Switch. 

Since I was the only one that mentioned it (as an example); it’s not on there, that’s the point. Neither are any other of my favorite games. It could have the power of the biggest supercomputer out there, then still even GameBoy would be better because it has one of my favorite games while a phone does not. Now I realize that the phone companies aren’t necessarily aiming at the established console gaming crowd, so I fail to understand why this comparison was necessary when it was probably better to compare it to another high end phone.
