DROID Turbo to be Updated Straight to Android 5.1 (Droid-Life)
"According to Luciano Carvalho, an engineer at Motorola, the DROID Turbo on Verizon is to receive an update straight to Android 5.1, bypassing all versions of Lollipop before it. Not to waste resources, the reasoning to skip other builds is stated to be Verizon’s urge for the device’s software to highlight VoLTE (HD Voice), which is native to Android 5.1. Beyond that, no other reason is listed."
