Proximity sensor fault

[Arulkumaran]

It's full of manufacturing defects,
And sony will not make replacement,
I had bought a new sony Xperia m5 dual only one month before,
The proximity sensor doesn't work properly,
When I ask replacement they are telling that they will repair and give it to me,
Is it my fate to use a repaired phone where it has manufacturing fault.

@Arulkumaran

I'm sorry to hear about your issue, but are you saying that users should NOT buy the Xperia M5 because you have a defect with the proximity sensor and that Sony is going to repair it but you don't want it to be repaired? 

[Arulkumaran]

I want my mobile to be repaired when it has fault on my usage within warranty period and (warranty terms and conditions),
But it is fault on manufacturing,
I'm saying it is a manufacturing fault because when I opened the mobile phone from the box and made a call but the red light in the proximity sensor doesn't glow and also the screen doesn't turn on when I remove the mobile phone from my ear during the call.
If it is a manufacturing fault they must replace and not to repair.
They should repair it only when it is not a manufacturing fault.
I didn't bought a new mobile to be repaired,
I've bought a new mobile only to be used.

1. Are you aware that this is a user based forum 

2. If that happened when you first opened the box, why didn't you returned it to the store?

I bought this mobile in online website with sealed and With bill okay,
I found that the proximity sensor problem after twenty days.
It is not necessary to deeply check and I also don't know about this on box opening time.

I thought that this device proximity sensor works without a red light glowing when I opened the box,
But after twenty days I've called sony Xperia helpline number and asked them my screen doesn't turn on and Also I asked them whether the mobile has red light glowing during call or not glowing? They told it will glow,then only i confirmed the fault

What do you mean by Red LED light?

AFAIK proximity sensor works when some object come closer to the phnes surface (covering proximity sensor).

You can check the sensor's working in service test menu *#*#7378423#*#*

You can also use Diagnostics app by Sony for this.

Which mean that the phone was working out of the box and then the phone started having issues, I'm still confused about which issue your phone is having but follow @ppgsk17 suggestion and also test the phone in >>> safe mode and repair the phone with XC

Dear @Arulkumaran

The red light you mentioned is notification light and there will be no such light visible when proximity sensor works. As said earlier you check it in diagnostics and if you encounter problems while calling, test in safe mode, if not resolved, perform software repair
