Sony has started pushing out a new update to its Xperia X smartphone. Arriving as version 34.3.A.0.206, the update is currently hitting single SIM variants of the smartphone, although dual-SIM models should also get it soon. The only visible change is a bump in security patch level - it says July after the update. No information on what other changes (if any) are included as a detailed changelog isn't yet available. Via
