Xperia XA colour screen appear when charging

[dero]

I have this issue with my new phone. It happens whenever I plug in for charging. when screen is off, it turns on itself with colours appear on screen from red to green, like rainbow. After I turn off, it appears again after an hour. It happens only when I am charging the phone.

When charging, it becomes warmer, I thought it is because of this screen colouring. Because it turns on and consumes battery during charging. I have to stand nearby the phone to turn off the screen whenever it is charging.

I will be happy to hear any useful advise about it.
