First! Sony rolls out the February security patch to its Xperia X family, beats everyone else
Great news for you, then! It seems that Sony is currently updating said devices with the February Android security patch. Rolling under build number 34.2.A.0.311 for the Xperia X and X Compact and 39.2.A.0.417 for the XZ and the X Performance, this update essentially makes Sony's latest crop of phones the most secure ones in the Android lineup — even Google has not rolled this one to the Pixels yet.
Anyways, good job, Sony.
