Samsung M52 5G Display Artifacts line

[IrinaPihidchuk]

Ihave bought a Samsung Galaxy m52 6 / 128gb phone. 
When I turn on the camera for Full mode, a horizontal artifact line appears at the top of the screen. 
With this problem I turned to the service center and sent a video of the defect. 
After diagnosis, the service center issued a certificate of technical condition where it did NOT CONFIRM the problem. 
The act is written technically sound. 
However, the problem remained. 
I called them and during the conversation orally the Samsung service center reported that the whole batch from which the phone was purchased is defective. 
But they will not officially confirm this problem in the act of technical condition. 
And without the official conclusion of the service center, the store does not want to replace the phone.
I gave the phone back to the service center. But I have no hope. 
I am angry with the actions of the service and the attitude towards customers. 
How to act in this case. And is it really a problem party. 
I also want to ask the actions of the service center are legal and is this attitude of the official Samsung service center a policy of the company as a whole?

I had same issue, i got it replaced and replaced also had same issues. Amazon took back and they've refunded..

The official Samsung service center does not confirm the problem with the phone. Because of this, the store does not want to replace the phone with another

[IrinaPihidchuk]

I sent the phone to the Official Service Center and reported that the phone was working and returned it with this defect. I have a question about the competence of the service center specialists. Because they do not see a defect in the problem!

Sad.. Samsung is going down day by day.. Try again with Service center. They need to check your phone outdoor, then they can see those lines. Indoor, those line never appear

Which phone did you buy after that?

[Sid_Karna]

Oh I remember, you are the one who complained about camera quality issues on A52S. Did you replace your device?

[Dineshsagar]

Yes, bas decision by myself. I went with Samsung again despite bad experience with M52..

[Sid_Karna]

Did you check the photos I posted from the same phone?

[Dineshsagar]

I think it's just a software issue,.. it happens only when you open camera on direct sunlight
