About an update, Twitter whistleblower @OreXda says that Samsung is planning to replace the physical buttons of the phone like the volume and power buttons with software. These changes you will not see in the Galaxy S23 or Galaxy Z fold/ Flip 5 but maybe see in the Galaxy S25 series or new version of KT.
IT House realizes that not only Samsung who trying to do something new, previously some other phone manufacturers trying to remove these physical buttons like Huawei Mate 30 Pro tried to remove these physical buttons and offer to change the volume with the touch and slide, and the power button remain the same.
But this one is not comming to Galaxy S23 Series or Z 5 Series. It will plan to use at S25 or Special Terminal for Korean Telecom

There is one more that tried something like that before the Meizu Zero phone in 2019, they are adopting a non-porous design and using pressure detection technology to virtual look for volume buttons on both sides. But they failed in this because of crowdfunding and can’t produce phones in bulk.
From the start, when smartphones came, the size of the power button becomes less and less day by day. Now, most phone manufacturers retain the power button and volume button in the phone, which most manufacturer follows in smartphones appearance.
