Information on technical model names of Xperia 10 III products (HQ-BT52 / XQ-BT52)
You may have noticed that on the back side of your Xperia 10 III, a technical model name is printed at the bottom, being either HQ-BT52 or XQ-BT52.
In other places, such as on the packaging or in the smartphone’s Settings menu under “About Phone”, XQ-BT52 should be displayed.
These 2 technical model names are actually product synonyms namely used for service, compliance and other purposes. Both represent official, standard issue and identical Xperia 10 III products.
