Xiaomi Mi 4 — Unethical behaviours in the newly bought mobile phone

Address:

Kanchipuram, Tamil Nadu

I bought a mobile through online booking and it was delivered on[protected].For the past 4 or 5 days the display of the mobile is not bright.I have checked all my settings but it doesn't work out.within 5 or 4 seconds after started using the mobile the brightness of the mobile dims off and it s very difficult for us to use the mobile.The drainage of battery is very often and the production of heat during charging is very heavy.And frequently I find some problems like the screen being paused, and not responding to the user.I don't know why these kinds of problems are arising within this much short period after buying.So please i really request to meet my needs as soon as possible.Please reply to my complaint at your early times ..I also wish to exchange my mobile of the same model if so possible. order ID: OD[protected]fe
