How to change aspect ratio of visible mobile phone screen?

A mobile phone display is a hardware thing that could not be changed through software or settings. But the visible screen on which we see content on our android phone can be changed by software or settings.

Let me explain it more deeply. Let’s take A4 size paper on which we could do anything, but think that you have to make a painting on it. Then you have multiple choices whether you can make a painting on the whole paper or you can also choose some part of it as the center only, or the sides, or anywhere in the page to make a drawing.

The same thing applies on the smartphone display. On the display you can draw anything on any part. Like if you wants to show the content of the android system on some part of the display like your mobile phone display’s aspect ratio is of 18:9 so you can change it to 16:9 aspect ratio or any other aspect ratio. Or like if we have a software or system which could make some part of the screen not usable and only some part of the screen show the whole content.

Now one more thing that there is no setting on the android system via which you can change the aspect ratio of the mobile phone visible screen. Hope so that it could be possible someday via any app or settings on android.<But wait we have some basic developer options that can do this. We will discuss them below.

Setting via which you can change the aspect ratio of your android smartphone?

Notch Hide Option

Nowadays many smartphones comes with a notch display (any type of notch). Now you may know that there is a setting on android through which we can remove the notch of the display not by physically but with a software we can hide the notch to show and make a black edge on the display of the mobile phone which hides the notch. This will reduce the height of the viewable display so that the screen looks more vertical while the width remains the same.
 
To apply this setting :

1 – First go to Display Options in the settings of your phone.

2 – And search for the notch option, click it.

3 – Now click on Hide Notch option.

4 – Now there may be many options inside the Hide Notch option depending on your mobile brand.

5 – Select the hide and move status bar option.

Through display cutout

Display cutout is one of the options that we can find under the developer options, with display cutout we can change the position of the icons like battery indicator, time etc on the notification panel. Also icons like navigation buttons (back, home, and recent). Display cutout consists of some options which can change the positions of the buttons differently like they made the icons a little bit above from the original position or a little bit down from the default one.

These basic settings are available to fit the screen icons and to adjust the size of the viewable screen according to different mobile phone’s display.

1 – Enable the Developer Option on your phone ( How to enable Developer Option on any phone ).

2 – Go to Developer Option.

3 – Search for the display cutout in the developer options.

4 – Click the display cutout option and you see 3-4-5 options in it.

5 – Select the Double Cutout option.

6 – Exit the Developer Options.

After applying above settings you will see some changes on your screen which indicates that you have done it right. But the overall process won’t get a cut here, some more steps you have to follow. And also the aspect ratio of your phone doesn’t change.
