How to dry out a Samsung phone

Last Update date : Dec 27. 2021

Have you accidentally dropped your device in water but can’t visit your local service center immediately? First, it is crucial to power off your device. This is due to the potential damage or corrosion that can occur in the internal mainboard from the heat that is generated by your device. Keep reading to find out more about the measures you can take if you drop your device in water.

Check 1. Turn off your device

If your device is waterlogged, make sure to turn off (shut down) your device. Moisture in the device can cause serious damage or corrosion to the mainboard. If the battery is removable, quickly remove the case, battery, USIM, etc. If your device is a newer model without removable batteries, immediately turn off your device.

Note:

To turn off Galaxy devices with non-removable batteries, press and hold the Volume down and Side key simultaneously for 3-4 seconds.

Check 2. Remove moisture

After turning off your device, quickly dry off your phone. Remove as much moisture as possible from the battery, USIM, memory card, etc. using a dry towel or a clean cloth. Be especially thorough when drying areas where water can enter, such as the earphone jack or charging port. Use a cotton bud to ensure complete moisture removal.

Check 3. Remove foreign debris

If liquids such as drinks, seawater, or chlorinated pool water, etc. get in your device, it is extremely important to remove the salinity or impurities as soon as possible. This is because the foreign debris may speed up the corrosion of the mainboard. After turning off your device, take out any removable parts, soak in clean water for approximately 1~3 minutes, then rinse. Afterwards, follow Check 2 and thoroughly dry your device.

Check 4. Air dry

After removing the moisture or impurities, leave your device to dry in a well-ventilated area or in the shade with cool air (from a fan). Air drying is recommended for devices that are waterlogged. Please note that attempting to rapidly dry your device using a hair dryer or hot air may damage your device. Moisture may be present in your device even after a period of drying, so it is best not to power on your device until you visit a service center to have it checked. After air drying, please bring your waterlogged device to a Samsung Electronics Service Center as soon as possible.

Check 5. Check the waterproof rating

Most Galaxy models are dustproof and waterproof and feature the highest rating of IP68. Although the highest ratings support up to 30 minutes of waterproofing at a depth of 1.5m, it should not be used in deeper areas or areas with high pressure. Your device may become waterlogged if it is at a depth of 1.5m for longer than 30 minutes.

Note:

• Dustproof and waterproof support may differ based on the device model, so be sure to check the device’s User Manual.
• An IP (Identification code for Protection) rating refers to the protection code of solids and liquids, and is a grade established by the International Electrotechnical Commission (IEC) regarding the durability of electronic devices against external impact and foreign debris. The first digit represents the dustproof grade (0~6) and the second digit represents the waterproof grade (0~8). In general, a waterproof rating of 4 or higher is classified as water-resistant.
• Device screenshots and menus may vary depending on the device model and software version.

If you’ve ever gotten your phone wet in the rain, dropped it in water or spilt liquid over it, you’re not alone. One study suggests 25% of smartphone users have damaged their smartphone with water or some other kind of liquid.

Liquid penetrating a smartphone can affect the device in several ways. It could lead to:

• blurry photos, if moisture gets trapped in the camera lens
• muffled audio, or no audio
• liquid droplets under the screen
• an inability to charge
• the rusting of internal parts, or
• a total end to all functionality.

While new phones are advertised as “water resistant”, this doesn’t mean they are waterproof, or totally immune to water. Water resistance just implies the device can handle some exposure to water before substantial damage occurs.

Samsung Australia has long-defended itself against claims it misrepresents the water resistance of its smartphones.

In 2019, the Australian Competition and Consumer Commission (ACCC) took Samsung to Federal Court, alleging false and misleading advertisements had led customers to believe their Galaxy phones would be suitable for:

use in, or exposure to, all types of water (including, for example, oceans and swimming pools).

Samsung Australia subsequently denied warranty claims from customers for damage caused to phones by use in, or exposure to, liquid.

Similarly, last year Apple was fined €10 million (about A$15.5 million) by Italy’s antitrust authority for misleading claims about the water resistance of its phones, and for not covering liquid damage under warranty, despite these claims.

How resistant is your phone?

The water resistance of phones is rated by an “Ingress Protection” code, commonly called an IP rating. Simply, an electrical device’s IP rating refers to its effectiveness against intrusions from solids and liquids.

The rating includes two numbers. The first demonstrates protection against solids such as dust, while the second indicates resistance to liquids, specifically water.

A phone that has a rating of IP68 has a solid object protection of 6 (full protection from dust, dirt and sand) and a liquid protection of 8 (protected from immersion in water to a depth of more than one metre).

Although, for the latter, manufacturers are responsible for defining the exact depth and time.

The popular iPhone 12 and Samsung Galaxy S21 phones both have a rating of IP68. However, regarding exposure to water, the iPhone 12 has a permissible immersion depth of a maximum of 6m for 30 minutes, whereas the Galaxy 21’s immersion limit is up to 1.5m, also for 30 minutes.

While IP ratings indicate the water-repellent nature of phones, taking most phones for a swim will land you in deep trouble. The salt content in oceans and swimming pools can corrode your device and cost you a hefty replacement.

Moreover, phone manufacturers carry out their IP testing in fresh water and Apple recommends devices not be submerged in liquids of any kind.

Luckily, water resistant phones are generally able to survive smaller liquid volumes, such as from a glass tipping over.

Checking for liquid damage

Exposure to water is something manufacturers have in mind when designing phones. Most Apple and Samsung phones come with a liquid contact/damage indicator strip located inside the SIM card tray.

This is used to check for liquid damage that may be causing a device to malfunction. An indicator strip that comes in contact with liquid loses its usual colour and becomes discoloured and smudgy.

A discoloured strip usually renders your phone ineligible for a standard manufacturer warranty.

If you have any of the more recent smartphones from Apple or Samsung, then your device will be able to detect liquid or moisture in its charging port and will warn you with an alert. This notification only goes away once the port is dry.

But what should you do if this dreadful pop-up presents itself?

Fixing a water-logged phone

Firstly, do not put your phone in a container of rice. It’s a myth that rice helps in drying out your phone. Instead, follow these steps:

1. Turn off the device immediately and don’t press any buttons.

2. If your phone is water resistant and you’ve spilt or submerged it in a liquid other than water, both Apple and Samsung recommend rinsing it off by submerging it in still tap water (but not under a running tap, which could cause damage).

3. Wipe the phone dry with paper towels or a soft cloth.

4. Gently shake the device to remove water from the charging ports, but avoid vigorous shaking as this could further spread the liquid inside.

5. Remove the SIM card.

6. Use a compressed aerosol air duster to blow the water out if you have one. Avoid using a hot blow dryer as the heat can wreck the rubber seals and damage the screen.

7. Dry out the phone (and especially the ports) in front of a fan.

8. Leave your phone in an airtight container full of silica gel packets (those small packets you get inside new shoes and bags), or another drying agent. These help absorb the moisture.

9. Do not charge the phone until you are certain it’s dry. Charging a device with liquid still inside it, or in the ports, can cause further damage. Apple suggests waiting at least five hours once a phone appears dry before charging it (or until the alert disappears).

If the above steps don’t help and you’re still stuck with a seemingly dead device, don’t try opening the phone yourself. You’re better off taking it to a professional.
