Samsung investigates setup glitch locking Galaxy S26 Ultra users out of their phones

A software bug in Samsung's One UI 9 update is leaving some Galaxy S26 Ultra devices stuck during initial configuration. The problem primarily hits users who factory reset their flagship phones after installing the new Android update, leaving them trapped on a black startup screen displaying a message that the webpage is unavailable.

Samsung forum representatives confirmed the glitch stems from an unstable system WebView connection to the company's servers on certain networks. As temporary workarounds, Samsung suggests switching between cellular data and Wi-Fi, updating browsers such as Google Chrome, or accepting new terms of service on the Samsung Account website via a secondary device. Until a permanent firmware patch or server-side fix arrives, users are advised to avoid factory resets. [1][2][3]

The setup failure adds to recent stability complaints following the delayed arrival of Samsung's Android 17-based software. Other owners of Galaxy S26 and S24 series handsets recently reported facing XML Access Denied errors that froze devices, forcing users into safe mode or prompting them to remove SIM cards to regain access.
