the samsung s22 only have one physical modem (Samsung Exynos 2200 chip contains a single modem), meaning that both sim cards share the same modem, so no dual active, rather dual standby. If you put two sim cards into the phone, and call both, one will always to go voicemail, or if you use sim card 2 for data, data pauses when on a call for sim card 1.
As more and more phones use a SOC which contains a single modem, finding a phone with dual active is going to become increasingly challenging.
