Samsung hasn't given manual shutter speed for the m31. I don't understand why they're doing this. You get this feature on a 7k redmi note 8. What are you going to lose Samsung? WHAT? They haven't even given this for the s 10 lite apparently... This is a 20 thousand rupee phone, and that's quite a bit for most people, and what's a pro mode without shutter speed? I'm very unhappy with this. I would have readily recommended a Samsung product to anyone, but not now, at least untill they fix this issue. This is very cheap of Samsung didnt expect this. The only way we can do this is by unlocking the bootloader and installing a treble ROM... I think. But that's too risky too. I just hope and really wish Samsung fixes this. If you do, then I'll be eternally grateful and you'll get an a71 purchas from my aunt :) so PLEASE DO SOMETHING ABOUT THIS.
