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.\r\n\r\nLet 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.\r\n\r\nThe 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.\r\n\r\nNow 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.\r\n\r\nAlso Read: How to enable Developer Option in Xioami?\r\n\r\nDeveloper option have some more advance setting options that you can use to customize the layout, animations, apperance, etc. of you android system. But here we are talking about the settings that would help us to change the aspect ratio of a mobile phone display.\r\n
What these options (Developer options) will do?
\r\nWe are going to use some developer options as well as some basic settings that may available to any android phone. These settings will change the aspect ratio of your mobile phone viewable display. What they actually do is that, they narrow the screen (viewable) of your android phone. These don't affect the width of the screen so that you can get a change in the aspect ratio. Below are the setting to do so.\r\n\r\nSetting via which you can change the aspect ratio of your android smartphone?\r\nNotch Hide Option
\r\nNowadays 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.\r\n \r\nTo apply this setting :\r\n\r\n1 - First go to Display Options in the settings of your phone.\r\n\r\n2 - And search for the notch option, click it.\r\n\r\n3 - Now click on Hide Notch option.\r\n\r\n4 - Now there may be many options inside the Hide Notch option depending on your mobile brand.\r\n\r\n5 - Select the hide and move status bar option.\r\nThrough display cutout
\r\nDisplay 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.\r\n\r\nThese 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.\r\n\r\n1 - Enable the Developer Option on your phone ( How to enable Developer Option on any phone ).\r\n\r\n2 - Go to Developer Option.\r\n\r\n3 - Search for the display cutout in the developer options.\r\n\r\n4 - Click the display cutout option and you see 3-4-5 options in it.\r\n\r\n5 - Select the Double Cutout option.\r\n\r\n6 - Exit the Developer Options.\r\n\r\nAfter 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. Now you have also to apply notch hiding setting on your android phone to change the whole aspect ratio of android system and indirectly of your mobile phone viewable display and also the apps or games that you open on it.\r\n\r\nFollow the above steps to hide the notch on your phone :\r\n\r\nOR\r\n\r\nYou can also follow the combined steps below to reduce the height of your mobile phone viewable display\r\n\r\nRELATED : How to enable developer option in MIUI 12?\r\nHow to change the aspect ratio of your mobile phone?
