Dear all first of all don’t buy xiaomo redmi note 4.
During just few months ago I have bought it. I have experienced great deal of severe problems with this device. From severe software bugs concerning clock falling out of sync do not being able to power the battery.
When talking about charging issue it is not upto software but its about hardware, micro usb charging port quity is extremely bad and it will stop functioning in just few months of daily use.
Sound issue: I m facing sound issue such as when playing mp3, video etc.it is very annoying to listen it. Its sound is like breaking the speaker.
