A55 grainy issue

[Amr6]

I have something wierd in my Samsung a55 display that whenever i'm in home with meduim source of lighting there is like texture it's like dirty screen filter(grainy), and when iam laying in my bed it's actually dark room the screen its like 240p all screen is with textures or like pixels dots, this happens only like indoor or like somewhere is having medium lighting.. i went to samsung service they told me it's not an issue and i told them Samsung a52s and even  a30 don't exhibit this they told me every model have different characteristics of there panel... So this an issue on my unit or this is normal for a55 units . No eye shield is enabled or something makes the display behaves wierd

I'm guessing this is similar to the green tint some previous devices use to have. Also this grain that can occur with some display panels. If you are still within the return period, you can send it back for a replacement. Although you may get the same problem. I returned a tab s7 plus which the screen was uniformed, replacement was perfect.

Actually it's only visible when there is only low or medium source of light this issue exsist that there is texture filter in all screen but when like there is good source of light like in sunlight or mall it's magical gone no issue, and also when iam in street at night source of light is poor or like medium i can see that texture but less than when iam like laying on my bed and scrolling on facebook i see the textures

You will see it more in low light, also think it's more noticeable when brightness on the device is at a low percent.

Yes, exactly , so this an issue that Samsung service center will accept it or they need issue exsist all time ?!

I think samsung already answered your question. They will probably say it's ecceptable. But as you have paid out money and you are not happy with the device it's worth seeing if they can do something. As I said I returned a tab s7+ as I was not happy with the display, so I returned for a replacement. I only just received the device at the time. If you have had your phone over 14 says, it will be covered under warranty.

@Amr6: The AMOLED display applied on the Galaxy A55 series devices uses the self-lighting of each pixel, and it displays the screen by adjusting the current flowing on each pixel. It has a characteristic (benefit) which allows it to display very dark areas that LCD can’t express.

Recently, some feedback that noise or stains are visible on some Galaxy  devices is a phenomenon that appears according to the difference in brightness occurring in some pixel areas when displaying the screen in very dark environments, and it is a unique characteristic shown in most AMOLED components. This is not a product defect.

In particular, some areas of the AMOLED display may show differences in brightness and colour depending on the characteristics of fine currents flowing through each pixel when using the device in a low-light environments, and this may cause the appearance of noise or grain. To reduce the phenomenon, please try changing the display mode to ‘Light’ mode. (Settings > Display > then select the ‘Light’), or adjust the display brightness via Settings > Display > Adjust the Brightness slider to your preference.

But is this normal when like watching videos and content like having light color or gray color like in wall iam seeing like a rough color not smooth color like texture or like iam seeing pixel arrangement or like noise this happens in night or in dark environment or medium lighting but when seeing videos with good lighting nothing issued.. however when like moving screen to eyes( not for sure sticking it to my eyes like my nose is on the screen😁), is this normal?!! Cuz when comparing this to other models like a52s or even a30 nothing from this is issued! It's producing smooth color unlike a55 producing in certain condition like dark and so on rough colors(in light colors )

I hope u get what iam trying to express the situation
