Dimensions.get('window').height not consistent in Android 14 and Android 15

Description

Hi React Native team

There seems to be issue with the latest Android 15 release,

The Dimensions.get('window').height seems not consistent in the model device Pixel6a , i think its same for other pixel devices which has latest android 15 recently

Android 14 (pixel 6a - emulator)	Android 15 (pixel 6a - real device)

I tried using the react native boiler plate which is running on 0.75.4
as you can see the numbers in the screenshot for height are different, so any idea whats causing the issue why Android 15 has different results from android 14, even if their model device is same?

Steps to reproduce

create new project from via npx react-native init projectname and begin running it
Use two android version for this test , particularly use Android 14 Pixel 6A , and another Android 15 Pixel 6A
i think any pixel version will do
Add this text as the content <Text style={{ fontSize: 30 }}>HEIGHT: {Dimensions.get('window').height} and begin comparing the two

React Native Version

0.75.4

this below is the Android 15 (pixel 6a) - Emulator version

but still its same with physical device , but idk why android 14 and android 15 has different height but it same model??

Same for me on Pixel 6 API 34 vs Pixel 6 API 35
Using height from useWindowDimensions() :
Pixel 6 API 34 height => 841.5238.....
Pixel 6 API 35 height => 914.2857.....

not sure but i think it was the bump of height in the bar found in the bottom of devices for pixel devices , idk 🤷 if im correct

I also use the hook useWindowDimensions height value
-> e.g const {height, width, scale, fontScale} = useWindowDimensions();

, and the differences is much bigger now , i think there is an issue with calculating the dimension for android 15?
any thoughts on this?

@alanleedev

@alanleedev could you take a look at this one when you have a minute?

@cortinico

@cortinico
This behavior is not well documented but seems like on Android 15 height for window and screen is returning the same.
Systems bars appear to be ignored.
Emulator screenshots. Left is Android 15 and right is Android 14 on same device type.
~~Looking into fixing this to match existing behavior.~~

Although we do not call this directly and is supposed to be deprecated since API 30 but there is some info in Display.getSize() documentation which may be relevant: https://developer.android.com/reference/android/view/Display#getSize(android.graphics.Point)

- API level 35 and above, the window size will be returned.
- API level 34 and below, the window size minus system decoration areas and display cutout is returned.

I guess this could be correct if forced edge-to-edge is enabled.
It does seem like same values is returned on Android 15 regardless of it is forced edge-to-edge or not.
Seems like it could be bit tricky to handle and not completely sure if this is something we should try to fix.

@alanleedev

What method could replace in place of Display.getSize() method ? If that is the case @alanleedev

so it seems bug in the api of react-native?, if thats the findings as well
hmm what should be the workaround for the meantime

any suggestions?

thanks

It is not a bug in react-native. It is actually how the Android API works currently. It behaves differently between Android 14 and Android 15. The question is should we do additional work on top of it to make it work like we expect it to. Doing this can get bit tricky is what I meant.

@mahishdino

@mahishdino @arnoldc We do not actually call Display.getSize() directly. I just found hints on what could be happening in its doc. The code that does the widow or screen height calculation is DisplayMetricsHolder.kt.

We are discussion what we should do about this. Will update once we have direction.

Fix Dimensions window values on Android < 15 (#47554)

Fix Dimensions window values on Android < 15 (#52481)

Fix Dimensions window values on Android < 15 (#52738)

Note that previous PR was reverted and we still need the fix.

I had the same issue and I solved it by using useSafeAreaFrame as explained here: #41918 (comment)

WOW! The most easiest Fix. Thanks a lot!

@alanleedev

@alanleedev is there a planned fix for this? Is the current dimensions api still inconsistent?

I see 3b185e4 has been included in a release, does this mean this issue can be closed?

@SimpleCreations

@SimpleCreations No, the dimensions are still inconsistent.
