There is no Good Lock Support on M Series. I am a Big fan of Customization. And its a bummer that my Device doesn't have a Feature that Other Mid-range Samsung Devices have. Requesting an Update for this Issue. Thankyou.
M series uses Core Versions of One UI so features like Bixby services and Samsung pay along with Knox security isn't there. They say it's because they're cheap but my M30s is certainly expensive than my A30 which has support for all of the above
