Orientation setting in app.json does not fully lock orientation (ex: status bar)

I have a clean installation of an expo app and I noticed some weird behaviour. While testing the App on the Expo App on iOS 11, I turned the phone landscape and saw the status bar move with the orientation even though the orientation is set to portrait in app.json. Also because of this, the tab navigation shrinks too.

Environment

System:
    OS: macOS 10.14
    Shell: 3.2.57 - /bin/bash
Binaries:
    Node: 11.4.0 - ~/.nvm/versions/node/v11.4.0/bin/node
    npm: 6.5.0 - ~/.nvm/versions/node/v11.4.0/bin/npm
IDEs:
    Xcode: 10.1/10B61 - /usr/bin/xcodebuild
npmPackages:
    expo: ^31.0.3 => 31.0.6 
    react: 16.6.3 => 16.6.3 
    react-native: ^0.57.8 => 0.57.8 
    react-navigation: ^3.0.8 => 3.0.8
App:
    iOS: 11

Steps to Reproduce

1. Turn the device landscape

Expected Behavior

The status bar should stay in a portrait orientation if the device is moved into a landscape orientation.

Actual Behavior

The status bar changes orientation to landscape.

I am experiencing this issue also, the orientation is locked on android but refuses to lock on ios, tested on real device using app.json to set orientation and screenorientation api and neither have any effect on the devices ability to switch orientations this is using SDK 35

Same issue here. This leads to unwanted behavior on Expo Camera module.
