No matter how strong the display is in your phone, still you should definitely apply tempered glass over your phone. Because no matter how strong the phone’s display is, there are always scratches on it. And the display can also break if it falls down. Friends, many such phones come to me, which are very clear to see from above, but due to falling, the display of their phone gets spoiled. And friends, there is a lot of difference between the price of the phone’s display and the price of tempered glass. You can get the tempered glass changed many times, whereas you cannot get the phone’s display changed again and again, because it costs a lot.

The same is saved because of the cover.
