Visible black lines and noise (for grey color) on lowest brightness

[OtakuKenz]

Hi!

I just noticed on my A73 that when brightness is set to lowest, I can faintly see marks (thick black lines) noise like thing when the screen is showing grey (such as the background in the menu when in dark mode).

It's only visible in a room with no light so it's not really a problem for me.

Just wondering if this is normal? I did not experience this with my A71 so I'm not sure if this is a defect or common with some superAMOLED? This screen does go more dimmer than the A71 so it could just be a problem with amoled at super low brightness?

I have the same "issue". It's not issue, its just as it is, manufactoring uperfection.

I see horizontal lines, couple of them, only in total dark room with less then of 5% brightnes.

It's normal for AMOLED, don't worry.
