I also had several issues with this and I have sent several emails to Xiaomi.
Xiaomi phones are good quality, though they have very poor support systems.
In one of my experiences, I emailed over 20 emails and waited about 6 months!!!!!
And in the biggest Xiaomi photography competition I was really disappointed with this company.
