Xiaomi already working on the Mi A3
Xiaomi released Mi 2 and Mi 2 Lite phones in the summer, and now they seem to be preparing for the new Mi A generation. Mi A3, under the code name orchid_sprout, found his place at the user interfaces on Mi 8 and Mi Mix 3 based on the Android Pie system.
Our assumption is that it is really Mi A3 because code name for Mi A1, while it was developing, was tissue and spring, for Mi A2 the name was jasmine_sprout, for Mi A2 Lite it was daisy_sprout. Get acquainted with all of your devices from Android One, so believe that orchid codename belong to the Mi A3 model.
However, now we know very little about the specifications of this phone. As soon as the NFC chip is heard, which means that Mi A3 will be the first Xiaomi Android One NFC phone. Most likely because of the NFC, the new Mi A3 will have a glass back. On the other hand, we do not know for sure when this phone will be carried out in the testing phase and will see the light of the day.Source
