Xperia X Dual Sim Dual Standby (DSDS)

Why does the xperia x dual model not offer 4G + 3G dual sim dual standby?
I think the third-party smartphone that uses Snapdragon 650 has 4G + 3G dual sim dual standby function, but it does not seem to be a hardware problem.
Also unofficially, the xperia xa dual model confirmed that the 4G + 3G dual sim dual standby feature was enabled through latest update.

Hi @renjun, welcome to the forum.

As you say, the Xperia X does not support having one SIM card connected to 4G and the other to 3G. I'm afraid I don't have any information regarding decisions taken during development but I will forward your thoughts about this as user feedback.

Thank you for sharing.
