Alongside the OnePlus 5 OxgenOS 4.5.5 update, OnePlus has also rolled out an update for OnePlus 2 users as well. Before you rejoice thinking it’s an out-of-the-blue Android 7.0 update, this one brings the much waited 4G VoLTE fix for all OnePlus 2 users, and is still based on the dated Android 6.0 Marshmallow.
The latest OxygenOS 3.5.9 update for OnePlus 2 users fixes an issue with 4G VoLTE reception. The 4G network option seems to disappear from phones sporadically for some users. This issue was first seen after the OxygenOS 3.5.5 update was released in December last year, which also brought along 4G VoLTE support.
OnePlus is gradually rolling out the OxygenOS 3.5.9 update via OTA to OnePlus 2 users. If you haven’t received a notification about it yet, check for the update manually by heading to Settings > About Phone > System Update on your OnePlus 2 smartphone. To recall, the OnePlus 2 OxygenOS 3.5.8 version was rolled out in March, and it was supposed to bring the VoLTE fix, but that didn’t happen.
Last month, OnePlus confirmed that the OnePlus 2 will not be getting Android Nougat update, indicating that the owners of the phone will have to stay content with Android Marshmallow. This came as a bit of a surprise as it was previously claimed that the smartphone will be provided the Android Nougat update. In any case, OnePlus 3T and OnePlus 3 are guaranteed to get the future Android O update.
As mentioned, OnePlus 5 users got the latest OxygenOS 4.5.5 update, and it brings bug fixes, performance improvements, Wi-Fi connectivity improvements, voice calling improvements, and much more.
