On Samsung phones that have one, you can hide the notch, i.e. the 'notch' whose shape varies according to the model but basically we can say that it is drop-shaped, as it houses only the front camera. This is found on Galaxy A10, Galaxy A20, Galaxy A30, Galaxy A40, Galaxy A50, Galaxy A70 while the exceptions are Galaxy A60, which has an angular hole, and Galaxy A80, which has a fullscreen display without notch. The Galaxy S10e|S10+|S10 smartphone line, on the other hand, has been equipped with a more or less large 'hole' to house the front camera, two in the case of the S10+ and S10. Not all users may like the notch or hole, so they may be happy to know that it is possible to hide the 'notch' or 'hole'. As? Thanks to a simple option that Samsung has implemented in the phones.
Explaining how you can hide the notch/hole is very simple: with the 'Hide Front Camera' option active, the software simply adds a black bar to the top of the screen so that the front camera is not visible, therefore all the pixels to the left and right of the notch are colored black.
It is possible to hide the notch on Samsung devices that have the 'Hide Front Camera' option, found in Settings>Display>Applications in Full Screen: here it is possible to press on the switch to activate/deactivate 'Hide Front Camera ' and then handle the notch break/hole hole as you like.
