TL;DR

• •Early One UI 9.5 test builds reveal a dedicated desktop-class interface for Samsung Internet when running inside Samsung DeX.
• •The redesigned layout introduces a desktop-style sidebar, side-by-side web viewing, and an integrated Galaxy AI panel with summary and translation tools.
• •The One UI 9.5 update is currently in internal testing ahead of its expected stable debut alongside the Galaxy S27 series.

Samsung is gearing up for its next major software release, One UI 9.5, and early test builds suggest the native Samsung Internet browser is finally getting a true, dedicated desktop-class mode tailored for Samsung DeX. Samsung previously expanded its browser footprint with a dedicated Windows app release and recently refined features like smart shopping integrations, but the mobile-to-desktop transition has historically relied on basic desktop site toggles or, more commonly, a stretched mobile layout.

According to a report by SammyGuru, One UI 9.5 could change that by introducing a desktop interface for the Samsung Browser app (Internet app) when it is specifically running inside a DeX environment. Instead of merely forcing a desktop user agent, the upcoming browser release will seemingly reorganize UI elements to behave like a traditional PC browser, making multi-window multitasking on external monitors significantly more seamless.
