Samsung’s Android 17-based One UI 9.0 update is causing startup problems for some Galaxy A57 users, with affected phones getting stuck before reaching the normal home screen.
Even though the reports are coming from Galaxy A57 owners only, there is a chance that the problem could affect other devices as well. Hence, Samsung owners are recommended to avoid the One UI 9.0 update for now, just in case.
The issue started appearing after Samsung expanded the stable One UI 9.0 rollout outside South Korea.
In South Korea, the Galaxy A57 is sold as the Galaxy Quantum 7, and that version received the update earlier without the same level of complaints.
Users Report XML and “Access Denied” Errors
According to reports from users on Reddit and X, the problem may be linked to an XML file error.
Affected phones can become stuck on an error page displaying either “Access Denied” or a raw XML document tree. In some cases, the device cannot move past the One UI 9 introduction or setup screens.

The problem does not appear to affect every Galaxy A57. Some users have installed One UI 9.0 without any issues.
However, there is currently no clear way to know in advance which devices will be affected.

No Official Explanation Yet
Samsung has not provided a detailed explanation of what is causing the issue or when a permanent fix will be available.
For now, users who have not yet installed One UI 9.0 may want to wait until Samsung addresses the problem.
Temporary Workaround
Some affected users say they were able to get their Galaxy A57 working again by booting into Safe Mode and then restarting normally.
This involves holding the Power and Volume Down buttons, opening the power menu, long-pressing Power Off, selecting Safe Mode and then restarting the phone normally once Safe Mode loads.
Several users say the workaround was enough to bypass the error, but it is unofficial and may not work for everyone.
Until Samsung issues a proper fix, installing One UI 9.0 on the Galaxy A57 carries some risk for users who have not updated yet.
