It’s all well and good being able to rotate your device’s screen between portrait and landscape orientations, but sometimes you can trigger this action without intending to and then get trapped in a cycle of trying to correct it. If you know that you are only going to require one screen orientation for the time-being, then fortunately you are able to lock it in one of two ways.
Firstly, you can swipe down from the top-right corner of the screen to access your quick settings pane and then tap on the Auto Rotate option. Alternatively, you can launch your Settings app and then tap
on the Accessibility option (listed under the System section). Once inside the Accessibility options, you can then tick or untick the ‘Auto-rotate screen’ option to allow it to rotate based on its position or to remain fixed in the current orientation – which is particularly handy if you are reading on your device and are likely to go through a range of positions. It’s easy enough to unlock if you need to rotate it at a later point.
