In a report from BusinessKorea, Samsung has officially confirmed that it plans "to unveil the new application processor at the time of launching a new Samsung smartphone," and that "there are no problems with the AP’s production and performance.”
In the meantime, the fact that it was not announced on January 11th, as previously announced by Samsung itself, started rumors about issues or even the one, coming from Dohyun Kim over at Twitter, which says that the SoC is canceled, and that the Galaxy S22 series will use Qualcomm's Snapdragon chip in all regions.
Korea Snapdragon— Dohyun Kim (@dohyun854) January 11, 2022
Exynos 2200 is G.O.N.E.
(It might be released later, but I'm sure that it's not going to be in Galaxy S22 series.)
To sum up what I heard,— Dohyun Kim (@dohyun854) January 14, 2022
1. Every Galaxy S22 Series model in every region will get Snapdragon 8 Gen 1.
2. Exynos 2200 is delayed, and because it's delayed, it "might" be used for other models later (Not confirmed, maybe for Galaxy Z Fold4 or something).
It is highly unlikely that Samsung has canceled or delayed the Exynos 2200 SoC this late, but anything is possible.
In case you missed it, the Samsung Exynos 2200 is meant to fix the biggest drawback of its predecessor, the GPU, which was pointed as the main culprit by Samsung itself. Unlike the Exynos 2100, which came with ARM Mali-G78 MP14 GPU, the new Exynos 2200 SoC uses a custom GPU co-developed with AMD and based on AMD's RDNA 2 architecture, bringing support for hardware raytracing on mobile as well as other neat features.
Samsung is still tight-lipped when it comes to the official Galaxy S22 announcement date, but most rumors point to February 8th.
