Screenshots of the PS4 on the phone?

I just want to ask what is the fastest and easiest way to copy pictures (ie screenshots) from the PS4 to your phone?

Ps app and ps messager

Download the app playstation messenger for your phone then send the screenshot you want to a friend you know.

Then you open the chat on ps4, open the picture again make a screenshot and then you have it up

From ps4 to USB stick, from USB stick to PC, in front of PC to mobile phone.

With an adapter it could still cut short by stick directly on the phone.
but I agree with you
