M55 Proximity Sensor Issue

[Kolos]

I have been using M55 5g for a month and experiencing terrific problems with the proximity sensor.

The proximity sensor response at a very weak point above the bezel near to speaker. A slightest of the movement during a call will light up the display. Moreover, if I use a spigen back cover, it covers the top portion and proximity sensor will not work at all. 

Is this issue only for me or is it a common issue with M55 5g?

Hi I tried this.
The proximity sensor works, but only at a very weak point.

A slightest of the movement during a call will lit up the display.

Using a case, it will not eork at all.

My question is, whether it is my unit is faulty or the whole series have such an issue.

Oh I must say, the proximity sensor works only if I touch, else it will not.
As per the desciption in the test, I should not touch it.
