A Galaxy S26 Ultra user on Samsung's Korean forums says their phone has been stuck on a critical error since updating to One UI 9. The screen goes black, the home screen never appears, and an error message reads, "The webpage is unavailable... for the following reasons." The user reports being unable to get past the startup screen after installing Samsung's major Android OS upgrade.
Samsung responded quickly. According to the company, "The development team has confirmed that this issue occurs when using an unstable system Web View on certain networks. We kindly ask that you follow the troubleshooting guide below." The suggested fixes are to update your browser, such as Google Chrome, and switch to a Wi-Fi network rather than cellular service. After that, users can try logging into their Samsung Account as normal. Samsung has not yet confirmed whether a future software update will fix the bug.
The problem appears to be specific, and it is unclear how widespread it is. However, One UI 9 has caused other issues. Reddit users reported an "XML Access Denied error" about two weeks earlier that froze devices, affecting the Galaxy S26 Ultra, Galaxy S24, and others. One user had to remove their SIM card to proceed, while another booted into safe mode with Wi-Fi turned off.
These problems are frustrating given how long users have waited for the Android 17 update. The Galaxy S26 series received it in the U.S. in late September, with T-Mobile customers getting it first in a 4GB download. The update has since rolled out to several budget phones and the Galaxy S25 and S24 series. Long delays followed by a serious bug like this raise questions about Samsung's quality control.
