Android 12 is going to bring a new feature called one-handed mode which will reduce the phone screen content and make it feasible for one-hand use.

In the last few years, the smartphone industry has witnessed huge growth across the globe. From thick bezels to edge-to-edge display designs, smartphone brands like Samsung, Xiaomi, OnePlus, Apple, and more have come a long way. During this journey the size and height of the smartphones has also increased for better media consumption. However, tall smartphones are always a bit difficult to use with one hand.
It seems that the problem of tall phones is soon going to be resolved as the upcoming Android 12 is reportedly going to bring a new feature called one-handed mode which will shrink the phone screen content and make it convenient for one-hand use. 
According to a report from XDA Developers, Google is developing a “one-handed mode” feature in the open-source codebase of Android. Further, the report suggests that the feature is capable of shrinking the screen size to 40 percent. Users can activate the one-handed mode by using gestures or with the three-button navigation mode. 
How to Activate One-Handed Mode on Android 12

• First, head to the setting app on your smartphone
• Then select the System setting option
• Tap on Gesture 
• Toggle on the One-Handed mode

Google is planning to add this feature to Android 12, but OEMs have already made their versions which used to be the same. Smartphone brand Huawei has also tried submitting its version of one-hand mode to AOSP, but for some unknown reasons the search giant Google rejected its addition.
