I have purchased redmi note 8 pro from Amazon on November 6th delivered on November 9th, this is my secondary phone so I didn't used a lot and didn't noticed first that incoming call voice is not hearing everytime am only calling back to people from this redmi note 8 pro.i raised this issue to customer care twice they told me to go to service center as i did, in service centre they said uninstall truecaller and i did, again same problem continues, again i went to service centre they took my mobile inside without any jobsheet(Velachery mi service centre 100ft road Chennai) ..then one day is fine.. again the problem is started today... Just disappointed with these phone..and Xiaomi cheating every redmi note 8 pro customers or just me...i dont want a repaired phone...i need a replacement..
