I saw a similar(but little different?) issue.

My (2a) was blinking green line between its screen and bezel.
I reported this issue to customer support (in Japan) and exchanged,
but new one also started blinking in a few weeks

I think (2a) has a potential display issue.

    Thanks for the information and apologies if I have misguided anyone and well I was not aware of that. As you know many other companies have their authorised service centre all over India and it is not hard to get a solution to their issues.

    Myself am using a nothing 2 and I know nothing is a newer brand to this global markets. Just sharing my worries. If the phone has an issue most of them will have to find ways to reach this services centres which makes it more expensive. As you know the nothing has all its manufacturing works done in India, and they does not have much services centres in India.

    And also Samsung and OnePlus have made free screen replacement on this issue. Just curious to know if nothing will do the same for its customers. With all due respect sir, for many people accessing the above said centres won’t be easy as you might be thinking.

    RakeshBhasi Yes, I also noticed this issue on the very first day of using the phone. It happens when we turn on the extra dim mode. I ignored it as the phone 2A has an Amoled display, and it usually performs the same on other devices too.

      I am taking nothing2a 15 days completed , my problem is the same in lock screen become wierd in low brightness. Can service centre replaced it and the problem increases day by day or not..?

      *I think that’s the refresh rate problem like nothing 1 and 2*

      I think it’s fake news if you see notch and battery icon is broad compare to little bit thin it’s not nothing phone..

      RakeshBhasi it’s not an issue it’s common with flexible amoled displays just increase the brightness, think of it as a feature not an issue.

      I got almost same bug as Takumi Ando but the pixel were green and almost on all the top of the phone.

      I send it back and now I have to wait 3 to 6 weeks to have information about it….
