🧠 What Is RAM Plus (Extend RAM)?

RAM Plus is a memory management feature from Samsung (One UI) that allows a device to use part of its internal storage as additional virtual RAM.

📌 Important points to understand:

RAM Plus is not physical RAM
RAM Plus uses storage (UFS) as temporary memory
Its function is to assist the system when physical RAM is nearly full

🔧 Where RAM Plus Comes From & How It Works

RAM Plus comes from:

The device’s internal storage
Dynamically allocated by the One UI system

The basic working process:

When physical RAM is nearly full
The system moves background apps to RAM Plus
Physical RAM is focused on currently active apps

Result: multitasking becomes more stable and apps are less likely to close unexpectedly.

⚙️ Main Functions of RAM Plus

RAM Plus is designed to:

Keep applications active in the background
Reduce app reloads
Assist multitasking (split screen, floating window)
Stabilize overall One UI system performance

On foldable devices like the Galaxy Z Flip, RAM Plus is especially useful when:

Switching between apps quickly
Using Flex Mode
Performing light to medium multitasking

👍 Advantages of RAM Plus

✔ More stable multitasking
✔ Apps close less frequently
✔ Useful on devices with 8GB–12GB RAM
✔ More optimized on newer One UI versions
✔ Suitable for daily use and productivity

⚠️ Limitations & Drawbacks of RAM Plus

❌ Slower than physical RAM
❌ Does not significantly improve heavy gaming performance
❌ Uses storage (very small potential wear)
❌ Less effective on older devices
❌ Can have a negative impact if allocated excessively

📌 RAM Plus improves stability, not raw speed.

⚙️ How to Enable and Configure RAM Plus on Samsung Galaxy Z Flip

RAM Plus on Samsung Galaxy Z Flip devices can be enabled and configured directly through the One UI settings menu. Available options may vary depending on the device model and One UI version.

✅ Steps to Enable RAM Plus

Open Settings
Go to Battery and device care
Select Memory
Tap RAM Plus
Choose the desired RAM Plus size (for example: 2GB, 4GB, 6GB, or 8GB)
Confirm your selection
Restart the device for the changes to take effect properly

📌 After restarting, the system will begin using RAM Plus according to the selected capacity.

📊 RAM Plus Size Options & Recommendations

Available RAM Plus options usually depend on:

Physical RAM capacity
Internal storage capacity
One UI version

General guidelines:

2–4GB → light usage, standard applications
4–6GB → daily multitasking, social media, web browsing
6–8GB → intensive multitasking, split-screen usage

⚠️ Setting RAM Plus too high is not always better.

🔁 How to Disable or Adjust RAM Plus

If the device feels less responsive:

Go back to Settings → Battery and device care → Memory → RAM Plus
Select a smaller size or choose Off (if available)
Restart the device

This is useful for users who:

Focus on heavy gaming
Have nearly full internal storage
Experience performance drops after enabling RAM Plus

❗ Important Notes

RAM Plus does not increase physical RAM
Its benefits are more noticeable for multitasking, not heavy gaming
Not all Galaxy Z Flip models have the RAM Plus option
On some older models, availability depends on region and firmware

📌 Recommended RAM Plus Usage Tips

✔ Enable RAM Plus if you frequently switch between apps
✔ Use a moderate size (4–6GB) for balanced performance
✔ Avoid forcing the maximum size without real need
✔ Make sure sufficient internal storage is available
