I'm a Galaxy A50s. As we know it has the EXYNOS 9611 chipset . The Pro mode in Galaxy A50s doesn't allow you to control the shutter speed and other options that are available on other galaxy devices that are cheaper and have the same chipset i.e. EXYNOS 9611. Then what's the use of buying an A series phone when a M series user is getting more feature than an A series user (Pro mode with more options).
It's quite odd to see phones like the M31s and A51 having same hardware and software and launch in same price segment but got extra feature in their camera option. I'm curious to see if Samsung gives this feature in upcoming ONE UI 3.0 update for the Galaxy A50s.
