I had two xiaomi phones and I had a terrible experience with both of them:It's impossible to tranfer files from phone to pc. There are many bugs in this procedures and the phone gets stuck while transfering.There are hundreds of bugs in the regular use of the phone, in the interface and in the software/hardware: the notification bar is badly designed, the wifi does not connect (despite being in front of the router) and things like this.Every system app is bugged in some hindering way, from the text editor of notes to the camera.It is impossible to see my notes online, something that all phone brands seem to try to deny you.There are other more serious bugs for which the screen goes black and the launcher keeps rebooting indefinitely, effectively blocking the phone. In this situation, it is hard even to reboot the phone.Sometimes, the phones produce noises even when their screen have been shut down for a long time, proving that the application is in fact still active. This makes me very concerned about my privacy.Lastly, it's incredibly hard to file a bug report and send it, as almost always this results in a non better specified error.I am never buying Xiaomi again. If I could, I'd give no stars at all.
