T-Mobile has had a pretty bad track record when it comes to updating their phones, especially Samsung devices. We first saw it in (in)action when T-Mobile indefinitely delayed the Galaxy Note 8’s Oreo update for several weeks, citing ‘bugs’. This time around, the April security patch was rolled out on the 13th and put on hold the next day, due to some users’ devices boot looping. However, T-Mobile’s website stated nothing about the delay, and we’re getting to know about it only now. The likelihood of the update being resumed is low, considering that there are newer security patches available and it would be an exercise in futility to push a two-month-old update to a device.
