Samsung Galaxy Book4 (Gray, 16GB RAM, 512GB SSD)| 15.6" Full HD Screen
1. Master "Multi Control"
This is arguably the "magic" feature of the Galaxy Book4. It allows you to use your laptop’s keyboard and trackpad to control a nearby Galaxy smartphone or tablet.
What it does: You can move your cursor off your laptop screen and onto your tablet/phone screen seamlessly. You can drag and drop files between them or type a text message on your phone using your laptop keyboard.
How to enable: Ensure both devices are logged into the same Samsung Account and have Bluetooth/Wi-Fi on. Open Samsung Settings > Connected Devices > Multi Control and toggle it on.
2. Turn Your Tablet into a Monitor (Second Screen)
If you own a Galaxy Tab (S7 or newer), you don't need to buy a portable monitor.
* What it does: It wirelessly extends your Windows desktop to your tablet, giving you a dual-monitor setup instantly—perfect for working in coffee shops.
* How to enable: On your tablet, swipe down the Quick Panel and tap Second Screen. On your Galaxy Book4, press Windows Key + K and select your tablet from the list.
3. Extend Battery Lifespan with "Protect Battery"
If you mostly keep your laptop plugged in at a desk, keeping the battery at 100% constantly can degrade it over time.
* The Tip: Samsung includes a smart charging limit feature.
* How to enable: Open the Samsung Settings app (search for it in the Start menu) > Battery and performance. Turn on Protect Battery. This limits the maximum charge to 80%, significantly prolonging the battery's physical lifespan.
4. Bridge Your Phone with "Phone Link"
Stop picking up your phone every time it buzzes. The Galaxy Book4 comes with Microsoft’s "Phone Link" pre-optimized for Samsung devices.
* What it does: It lets you make/receive calls, send texts, view notifications, and even stream your phone’s apps directly on your laptop screen.
* How to enable: Search for "Phone Link" in the Windows Start menu and follow the prompts to pair your Android phone.
* Pro Tip: You can set up "Instant Hotspot" here, allowing your laptop to connect to your phone's mobile data with a single click in the Wi-Fi menu, no password needed.
5. Use "Quick Share" for Instant Transfers
Forget emailing photos to yourself. Quick Share is Samsung's version of AirDrop, and it is incredibly fast.
* The Tip: Use this to send massive video files or documents from your Galaxy Phone to your Book4 (or vice versa) in seconds, without quality loss.
* How to use: Right-click any file on your desktop, select Quick Share, and choose your nearby Galaxy device.
6. Enhance Video Calls with Studio Effects
The Galaxy Book4 series leans heavily into AI features. One practical application is the Windows Studio Effects for your webcam.
* What it does: It uses the NPU (Neural Processing Unit) to apply background blur, Eye Contact (which makes it look like you are looking at the camera even when reading notes on your screen), and auto-framing.
* How to enable: During a video call (Zoom, Teams, etc.), click the battery/Wi-Fi icon in the taskbar to open quick settings, then click Studio Effects.
7. Locate Your Laptop with SmartThings Find
Laptops are easy to misplace. Samsung’s SmartThings Find network is built into your device.
* The Tip: This allows you to locate your laptop using your phone, even if the laptop is offline (using Bluetooth scanning from other nearby Galaxy devices).
* How to enable: Open the SmartThings app on your laptop and ensure "SmartThings Find" is configured.r
8. Optimize the Dynamic AMOLED 2X Display
Your screen is one of the best on the market, but it might not be set to its full potential out of the box.
* The Tip: Ensure you are using the 120Hz refresh rate for smoothness and HDR for media.
* How to check: Go to Windows Settings > System > Display > Advanced display. Ensure the refresh rate is set to "Dynamic" (60Hz-120Hz) or "120Hz". Also, check Samsung Settings > Display to tweak color profiles (Vivid vs. Natural) depending on whether you are editing photos or watching movies.
