LG V30 Split Screen & Multi Window Mode

Updated 6 November 2026 · Standard formula, shown below

The LG V30 supports split screen and multi window mode, letting you run two apps side by side on its 6-inch display. You can start it through the Recent Apps screen, the QSlide floating apps, or the dedicated multi-window tray, and you can adjust how much space each app gets. This guide explains every way to use it, what to do when it misbehaves, and how it compares to newer Android multitasking.

What Is Multi Window on the LG V30?

Multi window is Android’s built-in feature for viewing two apps at the same time. On the LG V30, which shipped with Android 7.1.2 Nougat and later received Android 8.0 Oreo, the feature works in two forms:

Split screen – two apps share the screen, one on top and one on bottom (or side by side in landscape).
QSlide – a floating window that hovers over another app, with adjustable transparency.

LG also adds a multi-window tray that slides out from the edge of the screen, giving you quick access to apps you can drag into the split view. Not every app supports multi window; developers can disable it in their app’s manifest. When an app doesn’t support it, you’ll see a notification saying the app doesn’t support multi-window.

How to Start Split Screen on the LG V30

There are three main ways to enter split screen on the V30. All of them work on both Nougat and Oreo, though the exact menu text may differ slightly.

Method 1: From the Recent Apps Screen

Tap the Recent Apps button (the square icon at the bottom right).
Swipe through your open apps and find the first app you want in the split view.
Tap and hold the app’s icon at the top of its preview card.
In the menu that appears, tap Split screen or Multi window.
The app will jump to the top half of the screen, and the bottom half will show a list of other recent apps.
Tap the second app you want to use.

Method 2: From the Multi-Window Tray

Open the first app you want to use.
Tap the Multi window icon in the navigation bar (if you haven’t customized it). If you don’t see it, go to Settings > Display > Home touch buttons > Button combination and add it.
The app will shrink to the top half, and the multi-window tray will slide out from the right edge.
Tap an app in the tray to open it in the bottom half.

Method 3: Using QSlide

Open the app you want to float over another.
Tap the QSlide icon in the notification shade (it looks like a small rectangle with a line through it).
The app will turn into a small floating window. You can drag it around, resize it, and adjust its opacity using the slider that appears.

QSlide only works with a handful of LG apps (Calculator, Calendar, Email, Messaging, Video, etc.) and some Google apps like YouTube and Maps. Third-party apps generally don’t support QSlide.

How to Adjust the Split Screen Divider

Once you’re in split screen, you can move the divider to give one app more space:

Drag the black bar between the two apps up or down to resize them.
To swap the apps, tap the two arrows icon on the divider.
To exit split screen, drag the divider all the way to the top or bottom edge, or tap the X on the divider.

On Oreo, you can also switch one of the apps by tapping the Recent Apps button while in split screen – the list will appear in the half that was last active.

Common Problems and Fixes

Users often hit a few snags with the V30’s multi window. Here are the most common ones and how to solve them.

“App doesn’t support multi window”

Some apps (like banking apps or certain games) disable multi window. There’s no way to force it on a non-rooted V30. You can try the QSlide version if the app is in LG’s supported list, but otherwise you’re out of luck.

Multi window button missing

The multi-window tray button is not on the navigation bar by default. To add it:

Go to Settings > Display > Home touch buttons.
Tap Button combination.
Drag the Multi window icon into the active button area.

Split screen not working after an update

After a major Android update, some users report that multi window stops working. A simple fix is to clear the cache partition:

Power off the phone.
Press and hold Volume Down + Power until the LG logo appears, then release.
Use the volume keys to select Yes twice to confirm.
Choose Wipe cache partition and confirm.
Reboot.

This doesn’t delete your data, just temporary system files.

Multi Window vs. LG’s Dual Screen Case

If you’re considering the V30’s multi window, you might also wonder about the LG Dual Screen case (sold separately for the V60 and later models, not the V30). The V30 itself doesn’t support a dual-screen case. Its multi window is purely software-based, splitting the single display. The Dual Screen case on later LG phones gives you a second physical screen, which is a different experience – you can run apps independently on each screen without the divider constraint. On the V30, you’re limited to the software split, which is still useful for watching a video while texting, or comparing two documents.

Tips for Getting the Most Out of Split Screen

Use split screen with YouTube (in the app, not the browser) to keep watching while you browse the web.
Pair Google Maps with Messaging to keep directions visible while texting.
For reading and note-taking, put a PDF reader on top and a notes app on the bottom.
If an app doesn’t support split screen, try opening it in a pop-up window using the Popup Window option in the Recent Apps menu (on Oreo). This works for more apps than QSlide.

Frequently Asked Questions

How do I turn off split screen on the LG V30?

Drag the divider bar all the way to the top or bottom of the screen, or tap the X icon on the divider. You can also press the Back button – on some versions it exits split screen entirely.

Can I use split screen with any app?

No. Apps must declare support for multi-window in their code. Most Google apps, browsers, and messaging apps support it, but many games and some banking apps don’t. You’ll see a notification if an app can’t be used in split screen.

Why doesn’t the multi window button show up on my navigation bar?

It’s hidden by default. Go to Settings > Display > Home touch buttons > Button combination and add the Multi window button. If you don’t want to add a button, you can still use the Recent Apps method.

Does split screen work in landscape mode?

Yes. In landscape, the two apps appear side by side instead of top and bottom. The divider can be dragged left or right to resize.

Will split screen drain my battery faster?

Running two apps at once uses more CPU and screen power, so battery drain is slightly higher than using one app. It’s not a dramatic difference, but you’ll notice it if you’re streaming video and browsing simultaneously.

Can I save a split screen pair as a shortcut?

On the V30, there’s no built-in way to save a specific app pair. You’ll need to set up the split each time. Some third-party launchers offer this, but they require accessibility permissions and may not work reliably on all Android versions.
