Hello everyone. I have a MI MAX 3, Chinese version with Xiaomi Global ROM stable v10.0.1.0 (OEDMIFH), android v8.1.0 . The phone calls drop after 15 minutes of talking, but only when I’ve active voLTE on the SIM card. I haven’t any configuration to limit data. My operator is Vodafone Portugal. Does anyone have a solution for this? thank you.
