Hello. I have problems with my Mi Note 16 GB:
1. very often i have problems with call quality: i can't normally hear interlocutor - there are some interferences, etc. Interlocator also can't normally hear me.
And this problem appears when i make call to cellular phones. If i make calls to landlines (not for mobile phones) - this problem never appears.
2. ofter mobile network (internet) changes from 4G or 3G to E. And internet speed becomes very slow. There is only one solution: i go to "Settings" - "Mobile networks"- my network, "Operator networks" - i turn off automatical network selection, manually select 4G or 3G and apply changes. After that, i can set operator network to automatical select. This solution can work for few days, then the problem appears again.
How can I resolve theese problems ? I especially worry for first problem. Firmware: 6.5.26 from xiaomi.eu. I tried reflash my phone with firmware with wipes: system, data, cache, dalvik cache. I have changed sim-cards with new.
