People carrying around a Galaxy Tab S 10.5 on T-Mobile's network should soon see an over-the-air update come to their devices, and it's bringing Android 5.0. This news comes shortly after AT&T's announcement of the same update for its version of the tablet last week. The Wi-Fi model received Lollipop back in March.
T-Mobile's update starts today, and it bumps devices up to software version T807TUVU1BOE1. The full download comes in at 1.1GB, so it could take a while. But you're used to waiting by now. What's a few more minutes?
