T-Mobile is pushing a new update to the OnePlus 8 5G variant today that brings a few new features including support for two additional 5G bands. The device is currently sold by the carrier with support for only sub6 5G, since the model with support for both, mmWave and sub6 is sold by Verizon.
The OxygenOS update version 10.5.8.IN55CB is beginning to roll out to users that brings support for 5G bands 2 and 66. This is in addition to the bands 71, 41, and 5 that the T-Mobile version of the device already supported. The support for the two new bands does not bring any immediate benefits since the carrier’s nationwide 5G network runs on the 600Mhz low-band n71. However, as the carrier expands to offering more bands delivering higher speeds, the phone will be ready to leverage the benefits of the expansion.
The update also brings with it support for Google Live Caption. The feature helps transcribe the audio in media playing on the phone in real-time and is a nifty addition for those that are hard of hearing. The feature was made available to the unlocked versions of the OnePlus 8 in international markets (via XDADevelopers).
The update to the device is a minor one as per the changelog and comes in at around 306MB. It is beginning to roll out gradually to users, which means that it might be a few days till all users receive the update.
