A vertical white line suddenly appeared after plugging my S21 FE to charge... I used it for a while before charging it was all good. I thought it would have been a temporary glitch but booting it up and trying other gimmicks didn't resolve this for me. Another thing was I recently updated my cell phone and people faced the same issue post the update. I haven't caused any physical or virtual harm to my phone. I even considered the odds of voltage spikes but the charger used was of Samsung itself... in any case if it's from the charger that's on Samsung. I don't know what contributed to the issue, the update or the minor voltage event though I have been using the same provided charger as a loyal companion.
Scouring the Internet shed light that this issue is widespread and is mostly due to the hardware misalignment or display connector. Diagnostics confirmed persistent screen fault. I have been using this smart phone for a while now and I found it pretty great in terms of its functionality and ease of usage...however I can't tolerate issues like this come up without a definite cause. I would like Samsung to resolve this issue and others if near in distant future. Make sure you enable at least free screen replacement(excluding labour charges) for all users as buying a phone for a good price do not really bring peace if such issue arises out of nowhere.
As per your concern, we would request you kindly visit the service centre and inspect your device with the technical team end, they will provide you with all the information in a better way after inspecting the device physically.
I have bought my cell phone from Kuwait, however the label says its manufactured in India. The differing factor seems to be the Trading ID and other stuff. What keeps me apart from changing my display in India? Where can I do it if I want to resolve my "vertical line" issue? Because the centres keep denying from handling my phone saying "yaha ka piece nahi hai".
