New Delhi: Nowadays, instead of buying a new phone, many people prefer buying an old phone, and that is why the market of second hand phones is also increasing day by day. Whether you are buying the phone from an online platform or from a local shop, finalizing the deal without proper verification can cost you dearly. It is very important to be especially cautious about the phone screen, because this is the part with which you interact on a daily basis.
The life of any smartphone resides in its display. From making calls to watching videos, everything is done through this screen. In such a situation, if the screen is not seen properly while buying a second hand phone, then it is possible that you may get a phone with a bad display in your hands. Therefore, it is not right to be satisfied just by looking at the body of the phone, because even if the phone looks perfect from outside, any hidden defect in the screen is not detected.
What is screen burn?
When used for a long time, some pixels in the display of the phone gradually start weakening. The result is that a faint glimpse of an old app, icon or image remains visible on the screen forever. This is called screen burn. Many times this problem is so minor that it is not easily detected during normal use, hence it should be specially checked while purchasing the phone.
How to check your screen while sitting at home
The method of checking the condition of the screen is very easy. Just open YouTube on your or the shopkeeper's phone and search White Screen Test or Gray Screen Test and play any video there. As soon as the video starts, the entire screen will change to a uniform color. Now look carefully to see if there are any stains, different colored areas or the shadow of an old icon. If something like this is visible, then understand that there is a fault in the display.
By adopting this small trick, you can know the real condition of the phone screen in a few minutes. This will not only save your money, but you will also easily avoid the mistake of buying a phone with a bad display.
