A recent report stated that Samsung would ditch the physical buttons on the Galaxy Note10. But, the latest information that has surfaced says that won't be the case.
According to reliable industry tipster Ice universe, the Galaxy Note10 will retain the physical buttons like previous models. Ice says that Samsung did test a design sans the physical keys, but it did not pass the company's "rigorous testing."

That said, while the Galaxy Note10 will come with physical buttons, what it will be missing out on will be the 3.5 mm headphone jack. Something that this South Korean tech giant has retained on its flagships despite other brands ditching it in the name of bigger batteries.
The Galaxy Note10 is expected to go official in August, but you can expect to hear a lot more about it until then.
