Samsung Galaxy Z Fold 7 is a significant improvement from past generations of foldable devices with respect to durability, aesthetics, and protection.
One of the hot topics surrounding this device is its IP48 rating, which indicates a level of water resistance not often found on foldable devices. There remains a lot of confusion about what this actually means in practical terms for the end-user.
According to this information it’s already been demonstrated that while the Galaxy Z Fold 7 can withstand up to 30 minutes of exposure to water, it is not fully waterproof, and therefore it isn’t ideal for use in swimming pools, at the beach, or to take pictures underwater without some form of protection.
Below you will find everything you need to know regarding the Galaxy Z Fold 7’s water resistance, limitations, and safety guidelines. When discussing water-resistant foldable smartphones, the Google Pixel 10 Pro Fold stands out as a top choice. It offers an IP68 rating, which provides significantly better protection compared to the IP48 rating on the Galaxy Z Fold 7.
Additionally, the Pixel 10 Pro Fold is expected to be priced more competitively, making it a strong value proposition. On the other hand, the Vivo X Fold5 also positions itself ahead of the Galaxy Z Fold 7 in terms of durability. It features an IP5X rating for dust resistance and an IPX9+ rating for superior water protection, offering enhanced resilience compared to Samsung’s offering.
Understanding the IP48 Rating
The IP48 rating is made up of two key components: protection against solids (dust) and protection against liquids (water).
Water Protection (IPX8)
The “8” in IP48 indicates that the Galaxy Z Fold 7 can withstand submersion in freshwater up to 1.5 meters (approximately 5 feet) for up to 30 minutes. This level of protection is impressive for a foldable smartphone, as earlier foldable devices struggled with water resistance due to their hinge mechanisms.
In practical terms, this means the device can handle:
- Accidental drops in water
- Rain exposure
- Splashes from daily use
- Spilled drinks like coffee, tea, or soda
However, this does not mean the device is waterproof. It is designed for emergency situations, not intentional underwater use.
Dust Protection (IP4X)
The “4” rating for dust protection means the device is protected against solid particles larger than 1mm. While this offers some defense against debris, it is not fully sealed against fine dust or sand.
This is particularly important because:
- The hinge mechanism remains a sensitive component
- Fine particles like sand can still enter and cause damage
- Dust accumulation may affect long-term durability
Why the Galaxy Z Fold 7 Is Not Fully Waterproof
Despite having strong water resistance, calling the Galaxy Z Fold 7 “waterproof” would be misleading. The device is engineered to survive accidental exposure, not continuous or extreme conditions.
Here’s why:
- Saltwater and chlorinated water (pools, oceans) can corrode internal components
- High-pressure water (showers, jets) can break protective seals
- Repeated exposure can degrade water resistance over time
- The foldable hinge introduces additional vulnerability
Samsung itself advises users to avoid intentional submersion and to use protective accessories when necessary.
Real-World Water Resistance Performance
In real-world testing and everyday scenarios, the Galaxy Z Fold 7 performs well under controlled conditions.
What It Can Handle
- Up to 30 minutes in freshwater (up to 1.5 meters deep)
- Rain and splashes during outdoor use
- Accidental spills from beverages
- Light exposure to flowing water (with proper cleaning afterward)
What It Cannot Handle
- Beach environments with sand and saltwater
- Swimming pools with chlorine
- Long underwater usage
- High-pressure water exposure
Even though some tests show the phone surviving river water exposure, it’s important to note that these are controlled scenarios, and regular exposure can still lead to damage.
The Importance of the Hinge Mechanism
The hinge is the defining feature of the Galaxy Z Fold 7—and also its most delicate point.
While Samsung has improved hinge durability significantly, it is still:
- Vulnerable to fine dust and sand particles
- Sensitive to trapped moisture
Prone to long-term wear if exposed to harsh environments
If water or debris enters the hinge, it can affect:
- Folding smoothness
- Structural integrity
- Internal components
That’s why proper care after exposure is essential.
Practical Water Safety Tips
To ensure the longevity of your Galaxy Z Fold 7, following basic water safety practices is crucial.
1. Avoid Intentional Submersion
Even though the phone can survive underwater briefly, avoid using it in pools, rivers, or oceans without protection.
2. Stay Away from Sand and Dust
Beaches and construction sites pose a serious risk due to fine particles that can enter the hinge.
3. Clean After Liquid Exposure
If the phone comes into contact with:
- Saltwater
- Sugary drinks
- Coffee or tea
Rinse it gently with clean water and dry it thoroughly.
4. Dry Before Folding
Never fold the device while it is wet. Moisture trapped inside the hinge can lead to long-term damage.
5. Avoid High-Pressure Water
Do not expose the phone to showers, taps with strong flow, or water jets.
6. Use a Protective Case
If you plan to use your phone near water, especially outdoors, a waterproof case is highly recommended.
7. Keep the Hinge Clean
Use a soft cloth to remove debris and avoid scratching or blockage.
Can You Use It for Underwater Photography?
The Galaxy Z Fold 7 may support advanced camera features like Ocean Mode, but using the device underwater without a case is not recommended.
For underwater photography:
- Always use a certified waterproof case
- Avoid saltwater environments
- Ensure the device is completely dry before folding or charging
Final Verdict
The Samsung Galaxy Z Fold 7 has a remarkable durability boost compared to other foldable phones with an IP48 rating, which means this phone should help to protect against water damage from spills and accidental drops from rain, as well as very brief exposure to water (i.e. sprinkles or wet hands).
It is essential to note that there are limits to the use of this phone, as it was not designed for use while swimming or participating in underwater activities. Additionally, environments that may expose the phone to a lot of water (such as the beach, pool, and outdoors) create a greater possibility of damage. Proper handling and responsible usage can assist in helping the Samsung Galaxy Z Fold 7 remain at its peak performance for a longer period of time.
In summary, the Samsung Galaxy Z Fold 7 is an excellent option for an investment; however, when utilizing the IP48 rating as a guideline for safe and responsible usage, you are getting a protective safety net rather than a justification to take risks, but using your new phone in a less than acceptable manner would cause damage that will affect the functionality of this phone.
FAQ
Is the Samsung Galaxy Z Fold 7 good for all users?
The Samsung Galaxy Z Fold 7 is not ideal for all users, but it excels for a specific audience. It is best suited for productivity-focused users, multitaskers, and tech enthusiasts who benefit from its large foldable display and advanced multitasking features. However, casual users or those seeking a compact, lightweight, and budget-friendly smartphone may find it less practical due to its premium price, heavier form factor, and foldable durability considerations.
Can you take the Samsung Galaxy Z Fold 7 into oceans or sea areas?
No, it is not recommended to use or submerge the Galaxy Z Fold 7 in oceans or sea water. Even if the device has water resistance (such as an IP48 rating), this protection is tested in controlled freshwater conditions—not saltwater. Saltwater can corrode internal components and damage seals over time, leading to permanent damage.
What happens if you don’t turn on the Water Lock on the Galaxy Z Fold 7?
The Galaxy Z Fold 7 does not include a standard “Water Lock” feature like smartwatches. If the device gets wet:
- The touchscreen may behave erratically due to water interference
- Speaker sound may become muffled temporarily
- Charging may be disabled until the USB port is dry (a safety feature)
However, these protections are automatic, and no manual water lock activation is required.
