Have you dropped your phone in the water or spilled some liquid over it, resulting in your touchscreen not working even though the phone does power on?
To fix your touchscreen after your phone got wet, try these steps: turn off your phone, remove the SIM and microSD card, dry the device thoroughly with a cloth, put the phone in front of a fan, use silica gel packets (not rice) to absorb moisture.

Can water damage cause unresponsive screen?
A smartphone’s touchscreen can become unresponsive after suffering water damage.
As the phone is dropped into water, the liquid enters into the components and hardware and can result in the device no longer functioning. Water can also badly affect the touchscreen and make it unusable.
The screen may become unresponsive due to short-circuits resulting from minerals in the water, which affect the touch control circuit on the screen’s assembly. In many cases the screen will need replacement.
Does water damage a capacitive touch screen?
Most Android smartphones now use a capacitive touch screen, and water will typically damage its performance and precision.
When your finger touches the screen, a very small electric charge flows to the finger; which completes the circuit that results in the action being performed on the screen.
A drop of water, sweat, rain, or even extra moisture can result in the screen acting like it’s a “touch”, like when using your fingers.
Water also provides an added channel for electricity and interferes with the screen’s accuracy.
Why does a touchscreen not work when it is wet or the user’s fingers are wet?
A smartphone touchscreen won’t work properly when wet or when the user’s fingers are wet.
As water is relatively conductive, the screen will no longer correctly detect your wet fingers and correctly read touch gestures.
Water tends to make the screen “confused” and respond in an unpredictable manner.
How do I know if my phone screen is damaged?
If your phone has suffered from water damage, here are common signs that your screen is affected:
- Water droplets or moisture showing underneath the screen. This is often a clear sign of water damage.
- Blurry or foggy screen: the screen, or portions of it, may appear blurry, foggy, or cloudy.
- Dim or black screen: the screen may become hard or impossible to read.
- Lines on the display: there may be horizontal or vertical lines appearing on the screen.
- Liquid damage/contact indicator changes color: many Samsung Galaxy phones and Apple iPhones have a liquid damage/contact indicator inside the SIM card tray. If the device is water damaged, the indicator goes from white to solid pink, red, or purple on Samsung devices, or red on Apple devices
How do I fix an unresponsive touch screen after water damage?
You can attempt drying your phone after water damage and see if it dries completely and whether the touchscreen is working normally.
If your phone hasn’t dried completely or the touchscreen is not working, you need to take your phone to an experienced mobile repairing technician or the manufacturer’s service center.
The technician will open the phone and perform steps such as cleaning the motherboard and the connectors using a Printed Circuit Board (PCB) cleaner.
Also, the circuit around the screen and the board will be examined and cleaned or jumpered as needed.
You may have to purchase a screen replacement. Warranties given by smartphone companies sometimes do cover damage that occurs by accident, including for water damage.

What to do if my phone got wet and touch is not working?
You need to power off your phone immediately as this can cause short circuits in the phone’s internal components and lead to further damage.
Then you can attempt complete drying of your phone as described in the section “How do you fix a phone that fell in water and won’t turn on”.
How to unlock screen if my phone won’t swipe due to water damage?
If your phone has been dropped in water and has suffered damage, you should not make further attempts to unlock the screen if the swiping is not working.
It’s best to power off your phone to avoid shorting out internal phone components. Then, try these steps:
- Dry the phone with a soft cloth.
- Remove anything removable such as SIM card, SD card, battery.
- Allow the phone to dry completely for at least 1-2 days using an effective drying agent (e.g. silica gel).
- Don’t turn your phone on or try to charge it during this period
Does water damage cause ghost touch?
Water damage can cause ghost touch on your phone due to short circuits or damaged internal contacts due to water inrush between the phone’s middle body and screen assembly, or from ports such as micro-USB ports.
Ghost touch involves your phone responding to gestures you never made, causing things like text being typed or apps being launched on their own.
Ghost touch may also involve some parts of the screen becoming entirely unresponsive to your touch.
Water can also damage the digitizer, which is a thin layer made of glass on top of the screen that converts your actions to a digital signal that the phone can understand.
This can cause the digitizer controller to register fake touches or fail from detecting touches.

Can water droplet damage a phone’s touch screen?
Most Android or iOS smartphones use a capacitive touchscreen. These are prone to damage when exposed to water.
Water has its own capacitance and conductance. A high number of large-sized water drops can confuse the screen and affect its functioning.
That said, a very small number or small-sized drop normally will not affect the screen – simply wipe your screen with a dry cloth.
Can rain damage a touch screen?
Rain can damage your phone screen and other components if the device is exposed for a long time. Abundant rain may cause ghost touch, or make the screen unresponsive or simply defective.
In rainy weather, consider protecting your device from rainwater with a waterproof casing or pouch.
How do you fix a phone that fell in water and won’t turn on?
If your Android phone fell in water e.g. in a swimming pool or the toilet bowl, and won’t power on, here are steps you can take:
- Keep the phone powered off; don’t try to turn it on, press keys, or charge it.
- Remove the casing if any, and wipe the phone’s body with a dry and soft cloth.
- Shake the device in a gentle way to bring out water from the phone.
- Remove the microSD card, SIM card, and battery (if possible).
- Allow the phone to dry in a cool place in front of a fan.
- Avoid using an air dryer as this can cause overheating and further harm your phone.
- Do not put the phone in rice! A common myth is that rice will absorb moisture and help dry the phone. Instead, put the phone in a closed container filled with silica gel packets, which will act as a drying agent.
- Leave the phone alone for at least one or two days.
- If you believe your phone is completely dried, try to turn it on. Only if it turns on and everything seems to be working should you attempt charging your phone.
If the phone still doesn’t turn on, however, your best best is to take it to a professional.
