In addition to apparently linking the device to an operator, this update also prevents users from using two SIM chips. To make matters worse, the software also includes two applications considered bloatwares.
As you can see in the screenshots below, the Mi Telcel and Claro Música apps are added automatically after the update. This is somewhat contradictory, since we are talking about a phone with Android One.
For now, the Xiaomi did not manifest about what is causing this error. Anyway, the company’s forums in India are full of complaints, since there are cases where the device simply stops working after installing the update.
Therefore, we recommend that you exercise caution and avoid downloading any updates on your Mi A3. This is because it is best to wait to avoid unnecessary problems.
