Yes that is the light leak issue Elephone have. Or more precisely, the screen module's problem.

It doesn't affect any basic use, the light appears on the edge of the glass not the screen. So the display bit of the screen isn't affected. And the "leak" mostly visible when ambient light is dark and screen is bright (like having some white content)

Perhaps for some manufacturer it's not an issue as it doesn't affect use at all and only can see under certain circumstances.

But we decided to try to fix it. The process is not the easiest as we are not involved in the manufacturing of the screen module but we managed to make it to the way it should look like. And then a series of verification and reliability test needs to be performed again.

A lot of extra costs but this is our determination and promise to the customers.
