OnePlus 6 update optimizes call quality, fixes various issues

It's not even one month since the OnePlus 6 went on sale in select countries, and the flagship killer has already received several updates that added (or removed) features and improvements. The newest one doesn't necessarily bring any major changes, but it does fix some issues that some OnePlus 6 owners highlighted in the past few weeks.

If you've already received a new update tagged OxygenOS 5.1.8, then you should expect better call quality. According to OnePlus, the update is meant to optimize this feature, as well as fix some stability issues affecting the OnePlus 6.

Also, OxygenOS 5.1.8 update should improve network stability and adds some general bug fixes. Finally, OnePlus mentions that this specific build includes all the features that have been added in the OxygenOS 5.1.7 update (for India region).

Keep in mind that since the update is pushed out in waves, it might take up to a few days to reach all OnePlus 6 devices, so it's not available yet on your phone, give it one or two more days.
