Hi Team,

I need quick assistance and resolution for my problem. Please have a look at the following details along with your query.

Request type : Display found red green blue dots at start. later on each subsequent hour the screen was not clear(dots were becoming darker). Now the dots found spread across the whole display. The mobile is perfectly fine except this dark display issue. all touch screen points working, no any wear and tear from front, back, left, right, top and bottom side on screen and mobile comes under warranty period.
I approached Ahmedpur samsung center(Service Centre:[protected] - - SHRI KRISHNA MOBILE SHOPEE) and they raised a call for it with the upper office(Bill No : [protected] from service center). Service center got a reply from the answer team as the phone has some damage from the customer side.

My Key Points are:-
1. How come damage is suspected without looking at the Handset condition with only images sent from Office.
2. My mobile has no damage and if you want you can refer to all the attached images from all angles.
3. My mobile was validated by ahmedpur samsung service center executive with respect to (water, electricity, and liquid damage by opening in service center and they did not find any such fault related to it)
4. Upper office was asking for the damage, I am pretty sure I have not caused any damage to the handset by any angle. there is not a single pinpoint scratch on the phone.
5. on what basis my display is not being replaced and my issue is not resolved even if it's appearing in full warranty period (Appointment Date 05.16.2022 (14:31:42))??
6. I need assistance to resolve this issue from samsung india pvt ltd. I can make any assistance with respect to handset condition, bill and any documentation for further evaluations.
7. I also wanted to bring to your attention that on 13th May, 2022 there was a 1970mb update from Samsung for my F41 headset, I did download that install and it was installed successfully. I am suspecting the ripple effect of that update as well.
8. There is not a single damage to my handset either from inside and outside the peripheral area as well. I need the Handset to be repaired by Samsung India Pvt. Ltd., in WARRANTY period and make assistance as soon as possible.
