Many people recommended me to buy this phone as it is known to be a high-quality, cheaper version to iPhone.I certainly agree that it is a very stylish device.
Nevertheless, already after some months I had to deal with several problems regarding the functionality of this Xiaomi Mi 4i.
In irregular temporal distances I was not able to charge the device anymore, it was completely dead.Then, after some time it was suddenly working again. This issue was especially inconvenient when I urgently had to contact somebody.
Additionally, I have a lot of hazzles with downloaded and existing applications on this phone. They constantly crash down and I have to restart them again.
Also the camera focus for middle distances deteriorated after some months.
Due to these inconveniences I would not buy the Xiaomi Mi 4i again and I would also not recommend it to others.
