What to do if your Galaxy S6 is exposed to saltwater, other issues

S6 got wet

Hello everyone! In this post, one of the issues we address is an important issue about water damage. Unlike its predecessor, the Galaxy S6, the more recent #GalaxyS6 does not enjoy water resistance protection. This means that even a quick water bath may be enough to kill it for good. We hope that this post will enlighten those looking for concrete things to do in case their own S6 gets wet.

Problem #1: Galaxy S6 screen is black and won’t turn on

I did not do anything with my phone. It was a normal day with about 37 degrees C… i was charging my 5-month old S6 and suddenly it started vibrating like crazy…i immediately plugged it out and the screen was flickering a lot for about 5 minutes… i tried to boot it up but nothing worked… i tried rebooting it, pressing down on the sound and power and all the combinations possible but it will not boot up… i went to some forums to see wha’ts going on but all of their solutions were what i did already and did not work… my phone is charging fine, red, light blue and dark blue lights up at the LED corner but the screen is absolutely dead just like a person who is brain dead… sorry for the long text i just really need help on a clear explanation of what’s going on with my phone. — Norman

Solution: Hi Norman. We don’t know either. The information you share with us won’t change anything at all. If the screen remains unresponsive and black after doing any hardware button combination, the best course of action for you is to call Samsung or your wireless carrier so they can run some tests to check the hardware.

The screen assembly may be damaged resulting to this failure right now. Some of the common causes of screen failure includes shock from a drop, liquid damage, or temperature extreme exposure (either too much cold or heat). We are yet to encounter a case wherein a screen assembly fails without any of these causes. Because we don’t know the full history of your device, we can only speculate about the causes. You must have the hardware checked so the right resolution can be applied.

Problem #2: What to do if your Galaxy S6 is exposed to saltwater

So.. I’ll try to refrain from being dramatic but I apologize in advance for sounding whiny. I’ve been going through some serious problems in my life. I was recently terminated unlawfully, got some debt piling up and now my phone is in a terrible condition.

I accidently dropped it in some salt water. I immediately pulled it out and tried to power it down. Of course, as you know, it’s impossible to pull the battery out in a quick enough response. So I took off the casing and the SIM card as fast as I could. I immediately tried to power the device off but wasn’t fast enough. The phone’s screen lightened and had some flickering. I held the power button down and after some duration the device’s screen went black. I hoped it had cut off but as I got inside my house I noticed the notification blue light was still flashing.

Since I knew I was already going to have a long wait trying to dry everything out, I did what I figured was the best thing to do to try and remove other damage from future corrosion I moved to the next step. So to try remove any salt that could be lingering within, I ran my phone under a faucet to wash away all the debris. I’m not great at taking apart phones so I didn’t even try to remove the back to open everything up. I would of just ended up breaking the casing or the motherboard or anything else.. you get it.

So I put my phone in a zip lock bag (ones used in lab) designed for absorbing liquids within the bag itself that I also filled with instant rice. I know it’s considered a myth but I had to give it a shot. I then sat it under a rather small lamp that out puts a small but considerably enough heat to help pull all the moisture into the rice and the absorbent sheet. I made sure to turn the bag making sure that too much heat didn’t beam on any particular part of the phone. I couldn’t sleep for about 44 hours due to all the shit that I’d just gone through so I was able to tend to this project persistently.

Every hour or maybe longer( I’m not sure to be sure ), when I’d check it I would notice quite a lot of condensation or that the absorbent sheet slightly saturated. I’d change the rice and bag when needed.

Once I noticed that it was no longer dampening the sheet and condensation wasn’t accumulating I decided to give boot up a try. I turned it on and it turned on just fine. Once it booted to the home screen the background picture didn’t load but two figure tiny messages prompt on both the left center and the right center of the screen. The first message was just a notification of something like ifunny or some shit. Then another message would pop up immediately after stating something like “Battery in critically condition”. I’m not sure the rest because it faded rather quick. Soon after a message would appear that says “Charging paused, battery temperature too high” then it would turn off.

Well I’ve tried a number of things to try and see if I could get the device to charge or just get the device to bypass the error and use the device while plugged in. So when I plug the phone in it just simply flashes red rotating screen display from the lightning bolt (gray) and a triangle with a red thermometer. I can start the phone in Odin mode without any issues of it shutting down. I can do the same in system recovery with no issue of it shutting off. (This is of course while plugged in )

Now.. I still can’t get the phone to boot entirely.. Now when I boot it I can get it to passed the Galaxy load screen all the way to the Sprint load screen. it lingers on the Sprint load screen for about 20-30 seconds then darkens for a few seconds then completely shuts down. Then it repeats the flashing red light with the lightning bolt and triangle.

I have performed a cache clear/factory reset but neither worked. I’ve cleaned the USB port thinking maybe there was an issue there messing with the temperature sensor. No results. I’ve gone to best buy and attempted to charge the battery on the wireless pad but no results there either. So.. I’ve decided that I don’t think that it’s the usb port but I do believe the battery is compromised and needs to be replaced.

My question for you, which will help me make my next step, is where exactly is the temperature sensor in the S6? I’m thinking that it is in the battery itself in the part the connects the battery to the USB port. Maybe not. Please advise.. I’m up for any suggestions. There have been a few more things I have tried and a few more questions with ideas as to how I might be able to diagnose the phone as to what exactly was damaged to see whether it’s worth fixing or just scrap. Please help. — Andrew

Solution: Hi Andrew. We are not sure how a Galaxy S6 reads a temperature reading from its battery, though we would like to think that it still uses the cost-effective thermistor, a tiny special chip that keeps track of heat changes, inside the battery itself. Almost all smartphone  batteries today use thermistor to measure temperature and apps that claim to provide temperature reading are actually simply using thermistor’s data. The error saying that the battery is in critical condition may actually be accurate… or a sign of something worse. We don’t know how knowing where the thermometer is located can help fix the issue but we don’t think an S6 has one. We don’t fix hardware for a living so we don’t have hardware specific information that you need.

The things you did after the device was exposed to water were right but may not be enough to prevent damaging some components including the battery. One of the lowdowns of having a non-removable battery pack is what happened to your device. In an ideal world, a user is supposed to cut the power right away after an electronic device got wet to prevent further damage. Not doing so will put the entire circuit at risk of being shorted, damaging it permanently. This means turning off the phone or removing the battery immediately. Leaving a running power source connected to the circuit is almost always a death sentence for any electronic device. Liquid, much more saltwater, can cause corrosion in the motherboard if not dried properly. Even a tiny amount of saltwater in a hard-to-reach component can lead to rust later on, causing eventual demise of your phone. Saltwater causes corrosion faster than ordinary fresh water simply because it leaves minerals in the circuit board. Such minerals will damage a circuit board in a matter of hours so time is of the essence when it comes to saltwater exposure.

Now, putting a wet electronics in a bag of rice is not exactly a myth so long as you prepare the device properly before doing so. Rice can serve as sort of a  desiccant, though we recommend that you use Silica — the adsorbent substance you find in shoe cases– instead. A liquid exposed device must be thoroughly cleaned first, the thing that you were not able to do because you cannot open the back part, with a special type of alcohol to remove debris and water before leaving it inside a bag of rice to dry. Not doing this defeats the purpose of leaving the device inside that ziplock bag.

Needless to say, you did the right things an average user needs to do when faced with the same circumstance although the effort was simply not enough. To put it simply, you did the first aid procedure but the case needs more advanced care. That the phone is still showing problems as we speak is a strong indicator that you need to have the phone checked by a professional.

Problem #3: Galaxy S6 won’t turn on

Phone won’t turn on, it was working fine yesterday night, but suddenly just shut down due to low battery (it was the Samsung shut off logo screen that appeared so I know it was out of juice). But then right after it shut down, a small sliver on the right side of the screen glitched/flashed. didn’t think too much of it, just brought it upstairs to charge.

now it won’t respond to anything. won’t turn on, and sometimes when I try to turn it on the right side of the screen flashes the weird glitch again. The only indication I have that the phone is still alive is the light on the top left corner flashes blue and red sometimes. I haven’t figured it out but it seems like its blue when I have it charging, and when I press on some buttons it turned red, but that doesn’t always happen.

I’ve tried all the button combos and nothing is working!!! Please help!!! — Zoe

Solution: Hi Zoe. The problem may be similar to Norman’s screen issue above. A red LED light on top is an indication of any of the following:

  • glows red when the device is connected to a charger and is charging.
  • blinks red when the device is connected to a charger but there is a problem with charging.
  • blinks red when the battery is low.

On the other hand, a blue LED light may indicate:

  • pulses in multi-tone blue while the device is turning on or off.
  • blinks blue for a missed call, message, or other notification.
  • blinks blue when you are recording voice.

If your phone’s screen does not respond when you try to turn it on, there may be a problem with the hardware. The only thing that an average user can do is to see if the phone can boot up in other environments. If you can not restart the phone in safe mode, recovery mode, or Odin mode, that’s a clear sign that software is not to blame. We think that your S6’s screen has failed at this time and the best thing that you can do is to ensure that it’s checked or replaced.

Problem #4: Galaxy S6 connectivity problems after Marshmallow update

Hello. I hope you have had a great week thus far.

The issues started on one fine evening when I had access to wi-fi and the annoying – “update software” symbol finally had the best of me. I succumbed and allowed my phone to update to the new Marshmallow software. Prior to this time my phone was fine.

However, once I downloaded the new software I noted significant issues with my phones connectivity to wi-fi and data. Wi-fi calling through Whatsapp and Facebook and other apps is impossible, it disconnects shortly after the calls connects. I can also not refresh apps such as a Facebook, either on wi-fi or on 4G. My Google Maps is not functioning either.

I think the issues I primarily have are more so pertaining to internet connectivity. I have wiped the cache on my mobile, but it has not done anything to improve my phones condition. The last straw is a factory reset… so I would be really grateful for your help!

Thank you! — Susan

Solution: Hi Susan. If these issues started occurring after a Marshmallow update, then the first two solutions that you must try first are wiping the cache partition and restoring phone and OS settings by doing a factory reset. There are no other “advanced” troubleshooting or solutions that you can do on your end as a user. Problems following an update can be caused by a c

corrupted system cache or a bad firmware. If this is the case on your phone, these two solutions should work.

If they won’t change anything, the problem must be related to an app, most probably an incompatible one. This is a common cause for post-update issues but one that most Android users don’t realize. Incompatible third party apps can create conflicts with an operating system which may result to instability or performance problems. If you have plenty of third party apps, there’s a chance that one of them may not yet be coded to work properly with Android Marshmallow at this time, or it may need to be updated first to become stable. Make sure that you observe how your phone works after a factory reset without installing any third party app to know the difference.
