Things you need to do if your Samsung Galaxy S7 Edge fell in water and won’t turn on after that

First off, the Samsung Galaxy S7 Edge (and S7) is water-resistant, not waterproof. While the IP68 rating is one of the selling points of the device, it’s more of an insurance assuring users the device may still work if it accidentally got submerged in water for a short period of time. That’s a fact, otherwise we won’t be receiving issues of water-damaged S7 Edge.


Just for the information of those who own this phone, when the device got wet and turned off on its own NEVER attempt to turn it on as that might make things worse. Somehow, circuit boards have minimal protection against moist but it’s very minimal that a drop of water may damage some chips, which can lead to more serious hardware issues including permanent hard bricking.

Water damage is also very unpredictable. The device may have gotten wet today and it may take a week before the small amount of moist can cause damage. Such is the case for some of the users who reported their devices just turned off and won’t turn back on or the so-called “black screen of death.”

As owners of expensive phones, it is imperative that you know what to do–and what not–in case your device gets wet, starts to act crazy and turned off after snapping underwater pictures. Liquid damage isn’t usually covered by warranty and it’s the kind of problem you don’t want to take lightly. Read on as I will explain concisely why you have or don’t have to do the things below.

Before we go any further, if you have other concerns with your device, make sure you visit our S7 Edge troubleshooting page for we have addressed a lot of problems with this phone since its release. You may also contact us through our Android issues questionnaire if you need further assistance. It’s a free service but we’re asking you to give us as much information about the problem as possible so we can give you more accurate solutions.

Step 1: Turn off your phone immediately / do not turn your phone back on

Once your phone gets wet or submerged in water, three things could happen; it might not be affected especially if all the ports are secured, it might stay on with screen randomly dims out or flickers, it might turn off the moment the water gets into it.

If the phone continues to work without having any issues, you’re lucky but closely observe it for a week to see if it will start to do unusual things like random reboots or shutdowns. If so, then somehow the liquid has gotten inside. Have the device cleaned up immediately to prevent it from getting worse.

Should the phone start to show some signs of possible liquid damage like flickering screen, random dimming of the display, random reboots and shutdowns, etc., turn it off immediately. It is common knowledge that electricity and water don’t mix well but when they do, your phone will be caught in a crossfire and it should be the one that gets damaged.

If your Galaxy S7 Edge, however, turned off the moment it got in contact with water, DO NOT turn it back on. Normally, if there is a short circuit, the phone will automatically turn off as the flow of current got disrupted. If you force it to turn back on, some components may be damaged and there’s no easy way to determine which chip got busted and that’s the easy part. The difficult part is to determine whether it can be fixed or not. The worst part is to replace it, which can only be done by expert technicians and sadly, there’s only a few techs that can do that.

Step 2: Never ever attempt to charge your water-damaged Galaxy S7 Edge

If we are discouraging you to turn off your phone that you just fished out of the water, then we strongly recommend you don’t charge it as you may damage both your charger and your phone due to short circuit and that’s a very bad situation to be in.

Personally, I saw a battery explode due to overcharging and I know it could happen if the battery is charging and there’s a short circuit somewhere. Typically, when this happens, the phone may heat up and so is the charger. If you’ve already plugged in the wet phone, immediately unplug it for safety.

Step 3: Do not shake the device instead unmount both SIM and microSD cards

Shaking the device isn’t the best way to get rid of the water from within as it goes both outwards and inwards. So, it might even makes things worse. The best thing to do at this point is to remove your SIM card and your SD card and leave the tray unmounted. Both the SIM and the SD cards can easily be damaged even by little water.

Step 4: Hold the phone upright to let the water out

There are no ports on the sides of your phone and the 3.5mm headphone jack has a little opening from the inside. It is more likely that the water will enter through the USB or utility port and that’s also the best way to let it flow out.

DO NOT use a hair blower to attempt to dry the phone out as water is trapped inside so it can’t really escape even if you’ve successfully evaporated it. The device has to be disassembled before using hot air to dry out its components.

Step 5: Put the phone in a bowl of rice

In case you can’t have the device checked by a technician yet, remove any third-party cases if any and then bury it in a bowl of rice.

For those who don’t know yet, rice grains are a good water absorbent. In fact, it absorbs water faster than a piece of cloth. Depending on when you can have the device checked, it’s recommended you leave the device buried for a day or two.

After this, you can try to turn the phone on and see if it does or if it shows signs of water damage and depending on how your device works, you can decide whether or not to send it in for repair.

Wrapping it up

For minor water damage cases, these steps will surely work. In fact, we technicians follow these simple ways to fix similar issues. The only difference is that we have tools that can make the drying quicker like blowing hot air. Besides, we are authorized to open the phone and closely inspect the components that might have been affected.

Therefore, if your Galaxy S7 Edge suffered liquid damage, try the steps above and then seek assistance from authorized technicians.
