The touch and tap method of navigation employed by modern smartphones generally poses a challenge for left-handed users. Left-handers only make up about ten percent of the population, which means they typically have to use things made for the majority, i.e., right-handed people. These simple tips should help make your Android device more suitable for left-handed use, especially when using the device with one hand.
First you need to get into your developer options, then you can enable the layout change. Here's how:
Go into Settings > About Phone.
Scroll down until you see "Build Number" and tap it seven times in quick succession. This will enable developer options (if they're not enabled already.)
Once your phone tells you you're a developer, hit the back button to go to the main settings.
At the bottom, right above About Phone, you'll now see "Developer Options" where it wasn't before. Tap it.
Scroll down and tap the box to enable "Force RTL layout direction".
Your layout should instantly switch, giving your left thumb better reach to tap everything you need without so much strain. In addition, you'll see the layout direction of your home screen has changed, making the basic functions of your smartphone a whole lot easier.
