Xiaomi India — phone charging

Address:

Jaipur, Rajasthan, 302017

My redmi note 4 was working absolutely normally, but as soon as i updated the software 6 days bake which was provided by mi itself; the phone started mis behaving.

Problem comes when i connect the charger. If the phone is on it won't charge, it will only charge on when i switch off the phone. What is this...

I have been using this phone for around 18 months never had any problem but now it a mess...

So please resolve the issue.
