If you live in America and own Galaxy Note 8, you have already downloaded the Android 8.0 Oreo – that is, unless you have bought your phone from T-Mobile. While the T-Mobile Galaxy Note 8 OS update was released in early June, T-Mobile withheld it soon after due to an unspecified issue. It is now unavailable, with neither Samsung nor T-Mobile providing an ETA. In other words, the update is unavailable and will not be available in a foreseenable future.
