A natural line on the screen is most likely the result of a hardware problem, such as a damaged relation to the show, according to tech review sites like TechRadar.
Some people believe a software upgrade might have caused the phones to heat up so much that it may cause a hardware problem or worsen one already existing one, leading to a clean line.
According to what others have said, it may happen after one drops their phone.
WHICH MODELS ARE MOST AFFECTED?
The clean lines seem to mostly change Samsung’s Galaxy S21 line phones, according to media reports from earlier this year.
In specific, the Galaxy S21 Ultra and S21 FE designs have been cited more often.
SamMobile, which publishes information about Samsung, said the problem has also been reported on designs including the Galaxy A73, Galaxy M21, Galaxy S22 set and Galaxy Z Flip 3.
In response to questions from CNA, Samsung said it was committed to providing , the best possible wireless experience.
” Product value continues to be one of our best objectives”, a spokesperson said.
However, Android Authority said devices made by companies like OnePlus, Oppo, redmi, live, Xiaomi, Huawei and Apple have also been affected in the past, with the primary cause also attributed to a technology fault.
” The only common thread between all reports on the green line issue on smartphones is that the phone has an AMOLED display”, the site reported, referring to a type of organic light-emitting diode ( OLED ) technology.  ,
It added that this issue does not appear to exist for phones with LCD or liquid crystal displays.
HOW CAN IT BE FIXED?
According to various guidelines, restarting the phone should be the first thing that needs to be done.
If the natural range disappears, it was definitely a software problem.
If it persists, equipment is likely to be involved, and the screen will need to be changed in a repair or service facility.
Buyers should go to an authorized service center, according to Samsung.
As long as there is no obvious physical or water damage, users who are still covered by the guarantee are likely to be able to get completely repairs or replacements, according to Android Authority.
Customers in India reportedly received a gratis, one-time screen substitute for some of Samsung’s Galaxy devices. Customers there are also offered a free lifetime display guarantee.
HOW TO AVOID THE Matter
There is no universally accepted solution to the natural line matter, which is unfortunate and impossible to fix.
The Tom’s Guide online tool does recommend, however, that mobile users delay application updates for the time being. If not, do the release in a nice and well-ventilated place to reduce the chances of the telephone overheating.
