There were similar problems in the past, but now many users have reappeared, complaining about a green bar appearing on their phone screen.
A frequent error in AMOLED screens is the appearance of a vertical green line on them, which does not disappear even after restarting. We usually hear about this in relation to Samsung phones, but it has also happened with other manufacturers in recent years.
This time around, mainly Galaxy S21 series owners have encountered something similar, according to reports, and unfortunately, the exact reason is not yet known. Some people's screens were damaged after the latest update released in April, while others may have experienced more intense usage (such as prolonged gaming) and the associated heating. Most of the cases are associated with the Galaxy S21 Ultra and Galaxy S21 FE mobile phones, but of course this can also happen with other models.
We don't yet know how common the issue is, and it's also possible that only a few isolated cases have emerged, but there have been a fair number of complainants, and this isn't the first time similar bugs have appeared. If someone encounters this, it's definitely worth reporting the bug to Samsung.
