Why can't the horizontal screen of the mobile phone be turned over?

Taking Huawei P40, EMUI 10 1.0 as an example, the reasons why the horizontal screen of the mobile phone cannot be turned are as follows:

1. Is the mobile phone set to not allow horizontal display? If yes, you can set the horizontal display and brightness through the menu to see if you have set the position. If the location is closed, click Open.

2. There may be a problem with gravity sensing on the screen of the mobile phone, so you can enter the experimental mode of the smart phone for monitoring.

This answer applies to most mobile phone models such as Apple, Huawei and Xiaomi.

The adjustment methods and precautions for horizontal and vertical screens of mobile phones are as follows:

Method 1: Open the home screen page of the mobile phone, then pull down the notification bar from the top of the mobile phone, continue to pull down the icon position above the notification bar, expand the notification bar icon, and then light the auto-rotation icon to automatically switch between horizontal and vertical screens.

Method 2: Turn on the phone, enter the phone settings, click on the screen and font, and turn on the automatic rotating screen. You can adjust the horizontal screen and vertical screen of your mobile phone in these two ways.

Matters needing attention

It should be noted that different mobile phones have different names for the adjustment of horizontal screen and vertical screen. Some mobile phones automatically lock the screen, some vertically lock the screen, and some rotate the screen.
