TRRS means tip ring ring sleve and it refers to how the 3.5mm plug is configured.

Almost all modern phones with a 3.5mm port support this configuration. No need to worry about this.
The only major difference is how this technique is being used. Apple has their system and Android has their version.
When you buy a headset choose or tell the seller what device you will be using and the headset will work fine.
For a visual guide. Apple compatible headsets has three buttons on the headsets cable when Android compatible headsets has only one button on the cable.
This image below represents the Apple version of this product. You can see three buttons: Plus, Play/paus and Minus.

Some samsung phones can take headsets with + and - buttons.
Problem is there's no definitive standard for this.

But there is. And Apple will charge phone makers an arm and a leg to use it.

Many manufactures has designed models in a range of years when they used the ctia standard. Also Sony used it in some of their early Sony devices.
Each designing their own solution they followed no standard. And many now only uses the regular omtp.
I found an old cached website describing the details

The old HTC hero used a 600ohm resistor, a 220 ohm resistor. This was a time when inovation happened every day.
Further down it describes:
"To detect and use an external input, the Samsung Galaxy S needs to see about 1600 ohms impedance between the microphone and ground pins. This will automatically disable the internal mic in the phone. To connect the output from a PC or other audio device into the phones mic input, you'll need to add a 1.6k ohm resistor in series. This is the same procedure that works with an iPhone."
As we know there has been tons of lawsuites and patent disputes with Apple. Finding the right document is not what I have the time for.
I can not confirm if Apple is the patent holder of ctia. Or if it is free to use. Because many devices does use ctia standard today. Perhaps under license you can use the technology?
Or there is a legacy ctia standard that Samsung uses that can handle multiple buttons but does not upset Apple for looking to similar to their solution?
