The curved displays will have it worse. This is because the flexes are bent and stressed all the time and this will lead to early delaminating and failure of the ACF connection. This is why Samsung top models get it worse, as most of their models are curved displays. People in the industry know curved displays have a shorter lifespan. And these lines are there since s8/s9. They do nothing much about it because it makes people buy new phones just like you don’t mind the battery going kaput.

iPhones using displays from Samsung also suffer from this but much lesser occurrence because of their flat surface being less stressful to the flex cable and joints.

Also, I believe even up to today they will still provide free repair on pretty old iPhones with green / pink / blue lines. But don’t quote me on Malaysia as we are a dump site.

I used to buy S series because it was great value but exynos is really Samsungs gift of sh!t to the whole non US world and telling us to eat it hot.

What’s worse is recently I was planning a move back to android after having a deteriorating experience with iPhones, and was browsing in a store. There were pixels, vivos, honors and lastly Samsung on display. The worst phones in terms of performance, lagging and response was the latest S series. You don’t get software right, hardware right, warranty right, then what for?
