when taking photo with light at the background with the rear camera of my iPhone 6s plus, there's a light blue colour square will appear (somewhat like a reflection of the light).
anyone has any idea what's going on?
iPhone 6s Plus
The blue square is the area the camera is setting focus and exposure on.
Tap on the area you are actually taking a picture of. For example, if you are taking a picture of a someone int eh room and the background is very bright (or dark), tap the face of the person to set the camera to that.

I was referring to this blue square. However the shape of the reflection tend to change with shape of source of light
Looks like the lens/camera is messed up.
Take me it to an Apple Store
Those are internal reflections. aka ghosting or lens flare.
If under warranty, make an appointment to have it looked at.

This recall as about different 6+ behaviour, but it's worth plugging your serial number in...
