A bug had reportedly been hitting some devices which caused them to randomly reboot.
Due to that, Samsung has decided to press pause on the Android Oreo rollout, as noted by moderators on Samsung’s forums. The statement said, ““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 minimised and the rollout of the update can resume as quickly as possible.”
Earlier this year, the company stopped the rollout of the Oreo update to the Galaxy S8/S8+ due to similar rebooting issues. The company fixed the bugs and resumed the rollout a couple of weeks later.
As of now, there is no information on when the Android Oreo rollout will resume on the Galaxy S7 and Galaxy S7 Edge.
