Recently we heard a rumor that Samsung was planning not to put any physical buttons on the Samsung Galaxy Note 10, opting for capacitive ones instead, but unsurprisingly it seems that might not be the case after all.

According to @UniverseIce (a reputable leaker) the Galaxy Note 10 will have physical buttons. But it seems the original rumor might not have been totally wrong, as they say that originally the Note 10 wasn’t going to have physical buttons, but that this didn’t pass Samsung’s “rigorous testing”, so the final model will have them.
