Full screen mode does not work for me on my phone

Hi, this can be fixed in a C++ project. First of all, go to the Source/PROJECT_NAME folder and create the CustomAndroidManifest.xml file with the following code inside:

<?xml version="1.0" encoding="utf-8"?>
<root xmlns:android="http://schemas.android.com/apk/res/android">
    <androidManifestUpdates>
        <removePermission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
        <removePermission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

        <loopElements tag="activity">
            <setStringFromAttribute result="activityName" tag="$" name="android:name"/>
            <setBoolIsEqual result="isTargetActivity" arg1="$S(activityName)" arg2="com.epicgames.unreal.GameActivity"/>
            <if condition="isTargetActivity">
                <true>
                    <addAttribute tag="$" name="android:maxAspectRatio" value="2.8"/>
                </true>
            </if>
        </loopElements>
    </androidManifestUpdates>
</root>

Then go to the PROJECT_NAME.Build.cs file and add the following code:

if (Target.Platform == UnrealTargetPlatform.Android)
{
    var manifestFile = Path.Combine(ModuleDirectory, "CustomAndroidManifest.xml");
    AdditionalPropertiesForReceipt.Add("AndroidPlugin", manifestFile);
}

This worked for me in UE 5.5.1
