In February, Samsung introduced a new series of Galaxy S10. These smart phones have headphone sockets. However, there seems to be no Galaxy Fold.
With the Samsung Galaxy Fold missing a headphone jack, this means that Samsung is preparing to remove the headphone jack on the upcoming headset. I doubt Samsung Galaxy Note 10 will get a headset jack. However, it is difficult to see that the Samsung Galaxy S11 will have a headphone jack but it remains to be seen how it goes with it and of course I hope to get a headset jack.
