Google’s far from done with Android 5.0 Lollipop. Because things move fast around here (for the most part), they’ve just pushed Android 5.0.1_r1 (build LRX22C) to AOSP. Typically, factory images will be published before an OTA can begin, so be on the lookout as we figure out exactly what’s changed in the latest update to Lollipop.
We heard word that a future update to Android 5.0 Lollipop would introduce T-Mobile’s WiFi calling baked right into the OS, but whether or not Android 5.0.1 is that update remains to be seen. We’ll keep you posted.
