Problem 1: Things to do when Galaxy S6 got water damage

Dear Droid Guy, I went on a run with my Samsung S6 edge in my running short pocket, I had a plastic case on. Whilst on my run it began to suddenly downpour. I was drenched (as if i had jumped into a pool). When i found some shelter i pulled my phone out and it was working fine. I then returned home and that’s when i realised that my volume from my mobile speaker was not working. I turned the mobile off and then back on again. To my surprise the volume worked again. However i went to use my mobile later in the evening and now the screen flickers and lots of lines  run through the screen. I believe its suffering some water damage. So i Currently have the mobile submerged in a airtight bag of rice. If this doesn’t work….what should I do? oh and as well as this ..the front camera has some moisture in it…so when the front camera is on ..the picture looks cloudy. Thank you for your time Kind regards.  — Yannick

P.S. How do i find out what Android version my mobile is? — Yannick Pakeeree

Solution: Hi Yannick. As you may have known by now, a Galaxy S6 is not waterproofed or even water resistant at all. It’s not uncommon for it to fail to work properly even when its internal parts are exposed to a tiny bit of moisture. If your phone was working normally before you got it wet, it’s safe to say now that water must have shorted a component/s. The best thing that you can do is to let a technician take the phone apart so internal components and/motherboard can be dried professionally. Of course, you also want to let a technician check the entire system for other abnormalities that can come from water damage. If you don’t have solid knowledge about electronics and about Samsung devices in particular, you may miss other hardware malfunction.

As far as basic rescue of a wet phone is concerned, here are the things that any user can do on his/her end:

Ensure that you take it out from water ASAP

A non-water resistant electronics like your S6 usually don’t have much time to protect itself from leaks. In general, it’s always recommended to stop potential water leaking into the hardware within 30 seconds of exposure. We don’t know how long your phone was exposed to water or moisture but we know for a fact that enough water had seeped inside to cause the speaker and the screen to go bad.

Remove the battery

Leaving the power source or battery inside your wet phone can be disastrous. Exposing the battery to water can damage it. However, a powered on phone that’s exposed to water can lead to more serious, permanent hardware malfunction. We know that the battery pack of your Galaxy S6 cannot be removed easily so that might have contributed to, if it was not the main reason of, the problem.

Take off any covers and external connectors

This is to prepare the device for the eventual drying process. You don’t want let some tiny moisture still in the gaps or crevices of the phone after you’ve dried the internal components.

Keep in mind that taking the phone apart on your own will void the manufacturer warranty. That means that Samsung may not accept the device for repair later on, even if you’ll them to fix it. If you have no choice though, you can go ahead and open the phone up to prepare it for drying. Make sure to separate the motherboard from other removable items such as the battery, screen, etc. You also want to disconnect the flex cables so you can dry them together with the rest of the disconnected parts.

Dry the device as thoroughly as you can

We assume you don’t have the tools used by professionals to dry wet electronics so drying your device on your own requires some effort and time. First, you want to remove any water from every part by gently shaking each component. You also want to wipe each part with a clean soft cloth or paper towel to remove as much water as possible. When it comes to the device’s lens or screen, try using a soft cloth or microfiber cloth to avoid scratching them.

Once you’ve already wiped each component (including the case, removable external storage device, and SIM card), use a hand vac to draw residual moisture from the main board and other circuitry. Be extra careful when using a vacuum cleaner or hand vac for this purpose as holding the device too close can generate static electricity which may damage it.

If you don’t have a portable vacuum to use, you can use “dry soaking” technique. This is done by utilizing materials with high affinity to absorb moisture such as rice or silica gel. Just put the dismantled parts in a bag of rice for at least 24 hours, making sure to turn them every 2 hours. If you’re using silica gel, put the parts and the gel inside a sealed bag for the same length of time.

Another drying technique you can do is to put the dismantled parts near a heat source such as the back of a powered on TV. Make sure not to put your phone directly over a warm device or direct heat like fire, hair dryer, or oven to avoid damaging components. Water generally evaporates in a few hours so putting your device near gentle heat source can hasten the process.

Let a professional check your device

Keep in mind that the steps above are meant to prevent hardware damage from occurring and won’t fix any existing damaged component. If your phone continues to show problems after doing all the steps above, let someone who does repair for a living check your phone.

Problem 2: Galaxy S7 won’t boot normally after exposed to hot environment

2 days ago, it was over 100 degrees where I live, which is really unusual. My phone said it was shutting down and would not charge or power back on until it had cooled. After a few hours, it still wasn’t turning on even though it wasn’t hot. When I tried charging it, the charging light wouldn’t go on and it would get warm. Now when I try to charge, it doesn’t charge, but it’s not warm any more.

I tried power/volume down, but when I select any option, nothing happens. Even though the charging light isn’t on, I think it must be charging some because otherwise my phone would be dead by now. Please help! — HelpinCali

Solution: Hi HelpinCali. Like water damage, exposing your phone to direct or ambient heat can lead to problems. We know you did not do this intentionally but as much as possible, you want to keep your phone in normal room temperature. The most that it can tolerate as far as ambient temperature is concerned is 95 degrees Fahrenheit. Beyond that, there’s a chance that the battery’s chemistry may change and lead to problems. The phone’s circuitry and main board may also be affected, which can cause other components to malfunction.

If your phone still powers on because the screen lights up, you may still be able to fix the problem by restarting the device to other modes. Below are the different hardware combinations that you can try as well the follow up steps for each of them:

Boot in Recovery mode

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  3. When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  4. Wait until the Download screen appears.
  5. If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  6. Use Google to look for a guide on how to do it.

Boot in safe mode

  1. Charge the phone for at least 30 minutes.
  2. Press and hold the Power button.
  3. Once the Samsung Galaxy logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  6. The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

If your phone still fails to boot back normally, or if you won’t be able to boot to any of the above alternate modes, there may be a hardware issue causing it. The reasons for an issue like this includes a bad battery, a malfunctioning power management IC, or an unknown motherboard failure. Contact Samsung or bring the phone to an independent service so the hardware can be checked.
