Amazing day Yang! I'm Jan. Samsung moderator. Thank you for sharing your suggestion here, I will make sure that this will reach our research and development department for further review. Let's hope that they will acknowledge this and will be included in the next update! Thank you and have a good day!
As of now the May Update brings Dual Recording. I've read somewhere that Director's View utilizes the feature found in the new processors (SD 888 and Exynos 2100) to use the three cameras at once. Hoping they can port it at older flagships though.
