The high-end of Xiaomi this year comes with the Xiaomi Mi 10, Mi 10 Pro, and Little F2 Pro. These three terminals share the use of the Snapdragon 865, the latest chipset created by Qualcomm to offer the best performance.
This chipset arrives standard-bearer with 5G technology that allows higher speed and lower latency in internet connectivity. The Xiaomi Poco F2 Pro has begun to be marketed in Europe and the first users who have acquired this new Poco terminal have begun to see that with SIM cards from at least Vodafone and T-Mobile, the phone incorrectly shows that it has 5G. Regardless of what the software says, it is not a 5G connection, Xiaomi spokesman Esteban Jing said in an interview with Tweakers. “The phone only has a 4G connection.”
This error is due to a configuration in the software that controls the Snapdragon 865’s X55 modem. “The software standard states that it supports 5G via DSS,” said Jing. That is dynamic spectrum sharing, a technique in which the transmission mast frees up a small part of the frequency space to communicate with a phone through 5G technology. At the rear, that 5G band also uses the core network of 4G infrastructure, but the radio technology used is part of 5G.
The Poco F2 Pro only supports 5G in the 3.5 GHz band, which will not be available in the Netherlands for years to come. The Xiaomi Poco F2 Pro cannot use 5G in other frequency bands, although it supports 4G in the frequencies that Vodafone uses for DSS. This error also happens with other providers and Oppo or OnePlus flagship smartphones.
According to Jing, displaying a 5G icon while users don’t have a 5G isn’t ideal. “It can be confusing for users,” he says. “When 5G is a little more established, I think people will understand better why it works that way.”
In response, Vodafone admits that users may see a 5G icon, while the connection is not via a 5G technique. Suppliers can choose from four configurations by displaying a 5G icon, as documented by the GSMA. The least stringent of these allows a phone to display a 5G icon when the mast and phone support it, while the phone and cell tower have a normal 4G connection.
