Android should make a phone with a better graphics card and with a screen that is slightly wider than normal phone. It should have a slightly bigger memory core. Mobile gaming is on the rise more than ever I just think it would be smart to roll something out ahead of the game. Also because In all personal opinion I absolutely want Android phones to always to better than apple products even though it's not that hard for them. Lmao
There isn't a company called "android" that makes phones. Google provide the base Android OS, manufacturers who wish to use it customise it to their hardware. So any company that wants to make a specialist gaming phone is free to do so (the OS is provided free, though if you wish to integrate Google services there are conditions), provided they believe that there is a commercial case for doing so. But "Android" won't because "Android" as a manufacturer doesn't exist.
So far nobody in the industry has concluded that this is a proposition worth investing in. You may think they are wrong, you may or may not be right, but it's a gamble that nobody has felt worth taking. Bear in mind that unless you are one of the market leaders the margins in this business are tight (companies the size of LG have pulled out of making phones because they couldn't make a profit), and a niche device will need to command a high price to be profitable, which then cuts the sales potential, making this a tricky balance to get right.
As a technical matter, when you say "with a better graphics card" I'm afraid no phone has a separate graphics card. The SoC (System on a Chip) includes a GPU, and the manufacturer uses that. I don't even know whether it would be feasible to do anything else, i.e. whether any SoC has the necessary connectivity to drive an external GPU (there's no obvious reason to include that in the design, and components integrated into the SoC have advantages in terms of bandwidth and latency). If there is an SoC that can drive an external GPU, and if anyone makes a suitable external GPU, that will be a more expensive solution. If not then you need to make a SoC with a more powerful graphics system, in which case don't you think that the existing SoC manufactures already try to do this?
If you think you can do better you had better have very deep pockets, because SoC design and manufacture is a job for the big boys. So far precisely 2 phone manufacturers design their own SoCs: Apple and Google. Apple have done it all along, Google have only started recently and have yet to catch up with the established manufacturers in most respects (their chips rely on a lot of Samsung IP), and if you think about how much money Google have to burn that tells you how difficult this is to do. Others use SoCs from specialist designers, with Qualcomm leading the game in performance vs power, and Samsung, MediaTek and HiSilicon all lagging to varying degrees (I didn't count Samsung as a manufacturer who make their own SoCs because strictly speaking their processor manufacturer and phone manufacturer are separate companies, though part of the same group, and their best phones actually use Qualcomm SoCs rather than Samsung ones).
So in reality your best bet for a gaming phone is to use the same Snapdragon processors that many current Android flagships use already, and hope that there is a sufficient market for a "slightly wider" phone with gamer branding. And then you hit the other problem that if your device is sufficiently different from the mass market for this to make a difference you need to persuade the game developers to write for your phone rather than just writing for the much larger market of "slightly narrower" phones.
