Samsung has suspended global rollout of its One UI 7 after a serious bug was discovered, one that reportedly caused issues with unlocking devices.

Samsung has been under pressure to deliver One UI 7 after a month-long delay. Unfortunately, Samsung suspended the rollout shortly after it began. The issue appears to be a bug that was discovered by the company’s Korean user base.

Samsung provided a statement to CNET, saying the software’s “new timing and availability will be shared shortly.”

“The One UI 7 rollout schedule is being updated to ensure the best possible experience,” the company added.
