Make Android 10’s Hidden Desktop Mode more useful on the OnePlus 7/7T and Essential Phone
Sorry Pixel 4 owners, this won't work on your phone
One of the most talked-about features prior to the release of Android 10 was desktop mode. When we first heard that Google’s next major Android OS would natively support desktop mode, we were hoping it would be something akin to Samsung DeX or Huawei Easy Projection. Sadly, it was anything but. Google built a barebones launcher for external displays so developers can test what their apps might look like on large displays, but they didn’t even bother adding display out support on the Pixel 4. Sadly, this means that Android 10’s hidden desktop mode is unusable on the latest Pixel smartphone, but if you have the Essential Phone, OnePlus 7/7 Pro, OnePlus 7T/7T Pro, or any other phone with video output over USB-C, then there’s a way to make it more useful.
First, here are some requirements that you have to meet:
Next, here’s how to set it up:
- Enable Developer Options on your phone. Go to Settings > About phone and tap on “build number” 7 times.
- Go to Settings > Developer options and scroll down until you reach the “APPS” section. Turn on “enable freeform windows” and “force desktop mode.”
- Reboot your phone.
Install this APK. It’s a customized version of the popular Lawnchair launcher with TaskBar integrated into it. This APK was made by XDA Senior Member farmerbb as a proof-of-concept to show custom launcher developers how they can add desktop mode support*.- Go to Settings > Apps & notifications > Default apps and set Lawnchair as the default launcher.
- Plug your phone into your monitor/TV using the adapter.
- In a few seconds, you should see the custom Android 10 desktop interface appear on the screen. You’ll have to grant TaskBar permission to “display over other apps” as requested in order to show the bottom bar. If you also want TaskBar to show your recent apps in the bottom bar, you should also grant it the “usage access” permission as requested.
I would wager that everything looks way too big on your monitor/TV right now. That’s because the default DPI for desktop mode in Android 10 is 320, which makes everything look huge. Also, the navigation bar/Android 10 gestural navigation pill probably looks unsightly on your display. There’s a way to fix this, but it requires the installation of another app by farmerbb.
- Disconnect your phone from your monitor/TV and connect it to your PC.
Download and install ADB on your PC.- Install SecondScreen from the Google Play Store. Make sure you’re on version 2.9.1 of the app with support for Android 10 Desktop Mode (as noted in the changelog.)
- Run the following command from your PC, as instructed by the app:
adb shell pm grant com.farmerbb.secondscreen.free android.permission.WRITE_SECURE_SETTINGS - Now you can control the UI of the external display using this app! It uses the hidden WindowManagerShellCommand to tweak the density to make UI elements appear smaller, overscan to hide the navigation bar, and/or resolution to match that of the external display. Play around with these values until you get something you’re comfortable with.
That’s it! Enjoy desktop mode on your Android 10 smartphone. We’re not sure why Google disabled DisplayPort Alt Mode functionality on the Pixel 4, so we reached out for comment and will update you if we hear back. If you’re a custom launcher developer interested in integrating TaskBar into your launcher, you can find the instructions here.
Update 1 (11/1/19 @ 2:17 PM ET): This article was updated to simplify the instructions on how to tweak the UI of the external display.
