Problem #1: Galaxy S6 Edge battery drain issue after water damage

Hi. I dropped my S6 EDGE in a water bucket just for a split second, which i know doesn’t matter if the phone got wet anyways, and i dried it with a towel right away. But well I try turning it off but the power button didn’t respond. so i tried to close all the apps and the home button stopped working, so i just waited for it to go to sleep and put it in a container with rice for 48 hours. Then after 48 hours of rice therapy, lol, i tried to charge it but only the battery icon showed up. It appeared not to be charging, so i took it to this CPR shop for a checkup, and they got it to start. They changed the battery, power button, and changed the charging port which made the home button worked again, as they told me. But now my phone won’t charge more than 10 percent, and it immediately starts going down like magic, from 10 to 1 like in minutes. What can i do? And what might seem to be the problem. PLEASE HELP. — William

Solution: Hi William. Well, first of all, we can’t know what the problem is. The specific hardware issue can only be identified by an attending technician and never by armchair speculators like us. There’s a chance that other hardware components may be damaged and escaped the attention of the technician.

Secondly, we don’t think the problem is due to bad software but you can try to factory reset the device and observe it for a day without installing any app. If the same battery behavior happens, that’s a clear sign of an on-going hardware failure. Again, we would like to make it a point (and we’ve been repeating this in all water damage-related issues) that electronics and water don’t mix. Getting an electronic device wet almost always result to hardware problems —  most of them permanent. If you can’t make the device work after doing basic software troubleshooting, the phone is most likely toast. In this case, you can bring the phone back to the repair shop so further hardware check can be done. The best resolution though is to simply invest in a new phone. Repaired phones usually have shorter shelf life than non-damaged ones, especially if corrosion has already started in the logic board.

Problem #2: Galaxy S6 stops charging after some time

I’ve been experiencing a problem with my Galaxy S6 for a couple months now. It is a “like new” refurbished phone. The problem began with the original fast charger and USB cable. Over time the cable began to work less and less with my phone until my phone wouldn’t even recognize it anymore. So I switched to a different regular USB cable and it seemed to solve the problem until the same thing happened again a month or two later. Now, I have gone through about 5 different cables and am starting to experience problems with the battery jumping percentages during the time it is off the charger. I am hoping you might be able help me in some way or have an answer. Thank you for your time. — Jacob

Solution: Hi Jacob. The first thing you want to do is to ensure that the charging cable and/or charger set is working. The USB cable in itself can get damaged if you don’t take care of it properly. We haven’t heard of a Samsung device gradually damaging a USB cable over time so the issue may only be on how you take care of your charger or charging kit. Try another known working Samsung USB charging kit to see if it works. If the new charging kit won’t work at all, then that should give you an idea that the problem may lie on the charging port or on the device itself.

If you think the problem is on the phone in itself, the next steps you should take is to isolate whether it’s software or hardware in nature. To do that, you simply have to do the basic software troubleshooting that we usually provide in our articles, namely wiping the cache partition, booting in safe mode, and factory reset. If nothing will change after doing all of these procedures, you can bet that the main cause of the issue is hardware in nature.

Since we don’t provide hardware troubleshooting in this blog, you must find a way to have the phone checked by a competent technician.

For reference, below are the steps on how to wipe the cache partition, boot in safe mode, and factory reset.

Wipe cache partition

  • Turn off the Galaxy Note 4 completely.
  • Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  • When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  • When the Android System Recovery shows on the screen, release the Vol Up key.
  • Using the Volume Down key, highlight the option ‘wipe cache partition’ and press the Power key to select it.
  • When the wiping of the cache partition is finished, highlight ‘Reboot system now’ and hit the power key.

Boot in safe mode

  • Turn off the phone completely.
  • Press and hold the Power key and the Volume Down key.
  • When the phone starts to boot, release the Power key but continue holding the Vol Down key until the phone finished restarting.
  • Safe mode will be display at the lower left corner; you may release the Volume Down key now.

Perform a factory reset

  • Turn off the Galaxy Note 4 completely.
  • Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  • When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  • When the Android System Recovery shows on the screen, release the Vol Up key.
  • Using the Volume Down key, highlight ‘wipe data / factory reset’ and press the Power key to select it.
  • Now highlight ‘Yes — delete all user data’ using the Vol Down key and press the Power key to begin the reset.
  • When the master reset is complete, highlight ‘Reboot system now’ and hit the Power key.
  • The Note 4 will restart but it will be longer than usual. When it reaches the Home screen, then begin your setup.

Problem #3: Galaxy S6 screen won’t work and remains black

I have been having an issue with my Galaxy S6 Edge that last night. It was working totally fine. I was on phone. In the morning i checked my phone and there was nothing but green light showed on the phone. I tried to restart the phone but failed to do so. I couldn’t see anything on the phone. i put the cell on charging; after a while the screen went black and i was only getting notification and nothing else. And it’s been 12 hours my phone is unresponsive and i am only getting notifications. My phone is showing nothing on the screen, the screen is black. i can feel the touch, and attend the calls but phone displays nothing, even if i try Skype. The camera is also not working. What has happened to my phone? Any idea. — Sabeen

Solution: Hi Sabeen. That the phone continues to receive notifications and even calls, that means that the issue is only isolated to the screen. This issue usually happens when the phone is dropped or exposed to water or elements. If any of these things happened on your device before, you can assume that there’s a hardware malfunction involved. Unfortunately, there’s nothing much that you can do on your end to fix this. Contact Samsung or your carrier so you can have the damaged part repaired or replaced.

Problem #4: Galaxy S6 bootloop issue after it got wet

Hi. I dropped my Galaxy S6 phone in water for a about 5 sec. I got it out, dried it, it was on when it fell in, and it seemed to be working. I tried tapping water out, and with a bit of tissue as well, in charging socket and headphone plug. While I was using it, I accidentally pressed the power button and it went into a bootloop. I tried turning it off/on with power button but just kept looping, then also screen was going green and some lines while looping. My mom tried holding it above radiator to dry it. then we put it in rice. I also tried holding down the home button, volume down and home, volume down and power, and now screen is blank but light in corner is still fading from lighter blue to darker blue. I don’t know what to do?

I have pictures on there that I forget to back up from a trip I just got back from, do you think they will be retrievable? I also just remembered I tried to connect to laptop when it just started doing bootloop to see if I could get pics, but then quickly stopped… I didn’t pay attention to corner light then though. also have taken out SIM card. and front cam seem to have condensation. I don’t know the android version but it is an S6 so I assume it is 6.oish… — Bonny

Solution: Hi Bonny. As mentioned above, water damage usually leads to hardware damage. The immediate procedures that you tried (such as wiping  the phone, putting it inside a bag of rice, etc.) are simply first aid steps to mitigate initial damage. You’re not supposed to turn the phone back on unless you’re 100% sure that no internal component is still wet. You are even required to immediately remove the power source, that is the battery, from the unit (we know this is not practically possible in a Galaxy S6 as the battery is difficult to remove). The fact that you attempted to power the phone back on while water may not be fully drained yet may have resulted to hardware malfunction. To answer your question on what to do, we say you have it repaired. That’s it.

As far as file recovery is concerned, that depends whether or not you will still be able to power the device normally. The current bootloop issue is due to bad hardware so unless the device is fully repaired, there’s just no way to access your files.

Problem #5: Galaxy S6 won’t connect to Wi-Fi

Both my phone and my tablet are having the same issue where they’re trying to connect to the Wi-Fi at my home that they’ve both been connected to before. They’ve both been connected to this Wi-Fi for over 6 months now and I don’t know why today is been any different. They will try to connect again and when it looks like it’s about to connect it will just start over and it keeps going in the cycle over and over with them just trying to connect to the Wi-Fi. I’ve tried turning both devices off and on after the Wi-Fi off and on I’ve reset the connection settings so that they forgot that this was their Wi-Fi and even re-entered the password and nothing seems to work. Is there something I’m missing here? What do you think I should do next to try to fix this problem? Thank you. — Brandon

Solution: Hi Brandon. If you are the administrator of your Wi-Fi network, which means that you have access to the router graphic user interface (GUI), make sure that the devices in question are allowed to connect. In a router’s GUI, an administrator can either allow or block devices using any available filtering system. If you don’t know what we’re talking about, contact your internet service provider (the provider of your home internet service) and ask for direct assistance regarding this matter.

If you are not the administrator of your Wi-Fi network, make sure that you let the proper person know of your connection problem so he/she can check if your devices are being blocked from connecting to the internet. Keep in mind that the Wi-Fi signal (the signal bars) you’re seeing in your phone is not an indication that connection to the internet is possible. The signal bars is only an indication that your phone or tablet is talking to the router, but the router does not allow it to connect beyond it, that is, the internet.

Problem #6: Galaxy S6 screen not working | Galaxy S6 screen not working properly

Hello! I am desperate for help. A few weeks ago, the weather was very hot. Like, 95 degrees almost every day. One day, my phone stayed on longer than it was supposed to (I have it set to turn off automatically every five minutes or so) And I found it on with the screen scrolling up nonstop. I immediately looked online, and it said to take out the battery and wait for it to cool down. I did this, and it worked. Throughout that week, my phone kept “overheating?” and doing this screen scrolling, and sometimes the screen would go black. However, after the weather cooled off, my phone stopped glitching, so I stopped worrying. Today, it happened again. Only this time I could not get my phone to work again. The screen stays black, sometimes it will turn on and I can use it for a minute or two before it goes black again. Sadly, I went into recovery mode to attempt and see if it could be a third party app issue, and somehow accidentally deleted everything on my phone.

So, for one, if there is any way for me to recover that data, it would be amazing to know. But there is still the issue of my phone, as of right this moment it will not even turn on. The phone still makes sounds as if its working, so clearly the touch screen is still responsive, but the screen is staying black. Thank you so much for any help you can give me. I am at college, and thus have no idea where I can get my phone checked on, plus I really can’t afford a new one. Thanks! — Tiana

Solution: Hi Tiana. First of all, if your files were only saved locally, that is, they were only kept on the phone and not anywhere else (like in a cloud service or to another device), then there’s no way to recover them. They’re gone for good.

For the second issue, the main one, kindly refer to our answer for Sabeen above.
