According to reports, it seems that the update has been halted temporarily due to the fact that users have been complaining that the update has been causing reboots. This is according to a report from Samsung’s European help forum in which a rep posted a comment which reads, “Following a limited number of cases where Galaxy S7 devices have rebooted unexpectedly with the Android 8.0 Oreo, we have temporarily stopped the rollout of the update. We are investigating the issue internally to ensure that the impact to the affected devices is minimized and the rollout of the update can resume as quickly as possible.”
This is similarly reflected on the Notices section on Samsung Canada’s website which reads, “S7/S7 edge Android O upgrade is pending a fix for a technical issue discovered post initial rollout, Updates will be shared as available.” No word on when the update is expected to resume but we guess Galaxy S7 and S7 Edge users will have to be patient and wait.
