Hi! I have a Samsung J7 2015 and my problem started 2 nights ago. It's true that temperature is a factor to this issue, as we are having low temperatures for the first time this year. But still, and after reading a lot about this, I can find a specific solution to this (kind of) annoying problem. If what jclovis31976 Flickering screen on low back light say is true (very interesting info), then what should be done to solve a corrosion problem? Because mine should be a mild one, as I take care not to expose my devices to extreme humidity. And if its a power related issue, is there a way to fix it? Is it related to the corrosion mentioned before?

And I couldn't find if any other user said this before, but should be taken as another "clue": To me, the flickering takes place from the lower 80/85% portion of the screen, and not the upper section, like a failure of some sort.

Thank you all for your time.
