OxygenOS 5.0/Android 8.0 Oreo update resumes for OnePlus 5
Apparently, issues with some European carriers have been blamed for halting the roll-out of the update as well. A few days ago, OnePlus announced that it's already working on OxygenOS 5.0.1, which is supposed to contain fixes for the bugs mentioned earlier.
If you haven't yet updated to Android 8.0 Oreo, your OnePlus 5 should soon receive OxygenOS 5.0.1, which contains all the changes of the first build and the necessary fixes. According to OnePlus, this is an incremental roll-out, so it will take a few days to reach to all OnePlus 5 devices.
