It says 5V/3A in technical specs, I wonder if that 3 A is a must, or is there anybody who can power RPi 4 model B via a standard 5V / 2A smart phone adapter.

Specifically, I would love to hear someone who uses a Samsung Travel Adapter(Fast Charging).

Model no: EP-TA20EBE

I'll alsoadd the picture of the adapter.

The Pi4 will run quite happily on a 1A supply, depending on what is connected. See Raspberry Pi Power Limitations

There is NO SUCH THING as a "standard 5V / 2A smart phone adapter" - all fast chargers work by using a higher voltage with each manufacturer using proprietary interface.

Most will supply 5V @ 500mA (the USB-C spec is 900mA @5V up to 20 V at 5 A), often more (although with the possibility of reduced voltage - after all they are designed to CHARGE batteries) but there is no standard, and there is no way of knowing what they will do when connected to a Pi.
