Can water damage affect touch screen

Phone wet and wont turn on? Heres what to do with water damage (hint: putting it in rice wont work)

If youve ever gotten your phone wet in the rain, dropped it in water or spilt liquid over it, youre 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

• ruffled 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 doesnt 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 the 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 10m (A$15.5m) by Italys 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 devices 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 21s 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. Its a myth that rice helps in drying out your phone. Instead, follow these steps:

1. Turn off the device immediately and dont press any buttons. 2. If your phone is water resistant and youve 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 its 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 dont help and youre still stuck with a seemingly dead device, dont try opening the phone yourself. Youre better off taking it to a professional.
