One UI 9.0 Update Leaves Some Galaxy A57 Phones Stuck During Setup
Some Galaxy A57 owners have reported that their phones cannot finish setup after installing the stable One UI 9.0 release. The affected handsets may show an “Access Denied” message or raw XML instead of the normal setup screens. The problem is not affecting all devices, Samsung has not confirmed a fix, and an unofficial Safe Mode workaround may help some users.
The stable One UI 9.0 release is built on Android 17. Complaints surfaced as the rollout expanded outside South Korea, where the same handset is sold as the Galaxy Quantum 7 and reportedly updated earlier without a comparable cluster of reports. User accounts on Reddit and X describe setup screens being replaced by an error notice or unformatted XML.
Only a subset of Galaxy A57 units appears affected; many owners installed the software without trouble. Samsung has not issued a technical explanation or confirmed an official repair. An unofficial Safe Mode method may let some people get past the blocked setup stage.
For Galaxy A57 owners, a failed setup could turn a routine software update into a temporary loss of everyday connectivity, banking, messaging, and work access. Because the problem appears limited, broader disruption may stay low, but affected users could face stress, support delays, and reliance on unofficial workarounds. The episode may also make some consumers more cautious about installing major updates immediately, especially on midrange devices.
