How to Increase the Edge Screen Size on Samsung Galaxy Phones Without Root

While the Edge Screen function on the Samsung Galaxy S6 Edge, S7 Edge, S8, S8+, and Note 8 provides a useful way to to access your favorite apps, tasks, and more, it can be a pain to activate especially since the newer phones are so tall! The size (and recognition area) can be tweaked in Settings, however, the maximum size you can set there is not enough for some users. If you feel like the edge handle is too small on your phone, you can easily change it to a custom value without root or much effort required, thanks to a tutorial originally made by XDA Senior Member Pedroc1999.

It was originally tested on the Samsung Galaxy S8+, however, we have also confirmed that this works on the new Samsung Galaxy Note 8 as well. It should also work on custom TouchWiz-based ROMs with edge features enabled.

Increasing the Edge Screen Handle Size on Samsung Phones (ADB)

For this tutorial, as always, you're going to need to properly set up the Android Debug Bridge in your phone and your computer. Luckily, we've previously done a tutorial on how to set up ADB. Be sure to check that out before continuing, as it includes complete instructions on setting things up on Windows, Linux and macOS computers.

Once you've set up ADB on your computer, then, you'll need to open a command prompt/terminal and enter the following command:

  adb shell  

Finally, to change the edge screen handle size to your liking, use the following command:

  settings put global edge_handle_size_percent insertvaluehere  

where you change "insertvaluehere" for a custom value. In this case, we want the handle to fill up the whole edge of the screen, so we're changing that to"100.00″.

settings put global edge_handle_size_percent 100.00

The handle size is still the default, though, so in order to make this setting stick just go into the edge screen handle settings. You'll find that the edge screen handle size has now become full-size. You're good to go!

Increasing the Edge Screen Handle Size on Samsung Phones (Terminal + Root)

If you don't have a computer handy, or you simply don't feel like setting up ADB or using a computer, you can do it straight from the actual phone—only if your phone is rooted. You will need to download a terminal app like Termux beforehand and give it root permissions, so be sure to download it from the Play Store before starting.

Termux (Free, Google Play) →

Afterwards, fire up your terminal app of choice and give it root permissions using:

  su  

Since you're already in the Android shell, you can simply change the handle size using:

  settings put global edge_handle_size_percent insertvaluehere  

again, changing "insertvaluehere" for your value of choice. Go to the handle settings to find and set your custom size.

Explanation

You can actually tweak the screen handle size in Settings, with a slider that goes small/mid/large, however, some found it to be really small even at the largest setting, which could be quite annoying given how tall the newest Samsung flagship phones are. Digging through the Settings.Global database you will be able to find the "edge_handle_size_percent" setting, which can be easily tweaked using the device's shell interface.

While this tutorial was originally tested on the Samsung Galaxy S8+, as we said at the beginning of the article, we have also confirmed that this tutorial works on the Samsung Galaxy Note 8, and it will probably also work on both the Galaxy S7 edge and the S6 edge as they both have edged screens and, therefore, edge features. This will not work on flat-screened Samsung phones that don't have this edge screen feature. If, however, you're running a custom ROM which enables edge features on your flat-screened Samsung phone, you will probably be able to take advantage of this tweak as well.
