Problem #1: How to deal with a wet Galaxy S6

Hey there. I came across your post in response to my device not charging. My phone has gotten some water damage today as it got wet for the first time. At first, my speakers were not working as well but that problem has been solved. Then, my phone would charge to about 7-9% but then fall back to 1%. The home and lock button were not working as well; this problem comes and goes but was last working when it was on. After that, my home button must have been jammed a little as the phone would operate is if i was pressing it. That problem solved itself out after a while as well however, it comes and goes. Just before my phone died, my screen would turn into a rainbow color as I plugged it in to charge. I would have to press the screen or home button to get rid of this. After a while it continued however, it would stop charging after this screen. It is currently dead now. Please let me know if you have any idea as to what I should do to fix this. Thank you and I greatly appreciate it. — Josh

Solution: Hi Josh. If all these problems occurred after the phone got wet, the best thing that you can do is to send the phone in so it can be dismantled, cleaned, dried, and repaired if necessary. Your phone clearly is suffering from bad hardware so there’s no software tweaks that you can do about it.

Ideally, you’re supposed to do a few important “first aid” procedures after your phone got wet.

Firstly, you want to immediately remove the power source, that is, the battery, to prevent shorting other components if they get in contact with water or moisture. Leaving a battery connected to a wet electronics almost always leads to problems. By using your phone after some water got in the logic board must have damaged some components at this time. We know that removing the battery pack in older Samsung Galaxy S phones is easy but not in an S6. Failing to do this critical first step must have already affected a number of metallic contacts and components.

The second thing to do after removing the battery is to dismantle the logic board and other components connected to it for easier cleaning and drying. The cleaning process in this situation must be done before cleaning to remove dirt and as much water as possible. An ordinary rubbing alcohol can be used but if you have a special cleaning fluid like the one used by technicians, that’s much better. The cleaning process is simple but you should not overdo it to prevent damaging the logic board.

Once you’ve cleaned the entire phone thoroughly with alcohol, the next step would be to dry the dismantled components. A popular way to do it is by placing the phone inside a bag of rice to allow the rice to absorb all the water and alcohol. This process cannot be hurried and may require a minimum of up to a week of waiting. Once you’re sure that the phone and its components are dried, you can then connect everything back up so you can test if it works normally.

In some cases, a phone will work normally again after doing all the steps above , but if your device will continue to exhibit a problem, you can assume that something must have been damaged. You must then send the phone to a service center to see if  it can be repaired. If repair won’t solve the issue, have the phone replaced.

Problem #2: What to do if your Galaxy S6 edge won’t back on

Hello! I have a Samsung Galaxy S6 Edge that will not turn on at all. I was driving around all day and using the Google Maps App to find where I was going, so by the end of the day my phone was about to die. Before I got home I went to check it and it was dead a bit sooner than I expected but I wasn’t worried and plugged it in when I got home. It’s been charging for a little more than 15 minutes and it’s still not responding to me at all… there is a little red light flashing at the top left, but if I click any of the buttons the battery picture with the charge percentage does not show up at all. 

I tried to reboot it a few different ways, following all the instructions on your web page, but the screen remains completely black no matter what I do. The Samsung logo doesn’t come up or anything, the little red light just keeps flashing and that’s literally all it will do. Please help! I am waiting on a potential job offer to call me this evening or tomorrow and I cannot afford to miss that call! Thank you so much for your help and time. — Alissa

Solution: Hi Alissa. The only thing that you can do in this situation is to see if your phone will respond if you boot it to other modes. If the phone remains unresponsive, you should have it checked by a professional.

For reference, here are the steps that you can do and the follow up troubleshooting the you must do for each boot mode:

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 S7 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. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. 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 S7 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 S7’ 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.

Problem #3: Galaxy S6 won’t start back up after repair

Hello. Yes I dropped my phone off of the top of a building I was roofing and when it hit, it shattered the screen so bad you couldn’t even read what was on it. Well after I took it apart, you could tell the back was bent so I ordered a new back and digitizer LCD. well after spending about an hour switching all the components from one back to the other, then from old LCD to the new one, I put it together and plugged it in. It came on just like always, everything worked, but the front camera ear piece, every thing that was on the front camera ribbon. So I took it back apart and sure enough it was cut and after looking at the ribbon attached to the old LCD, that ribbon was cut too from glass off digitizer LCD. So long story short, I left it like that and ordered a ribbon.

Well, two days later the touch screen started working when it wanted to. So, I was using my Bluetooth wireless headset to answer and hang up but so then every time I want to use the touch screen I would have to twist out one way or the other and turn it on and off and before long no response at all.

so I ordered another screen set for it; it came yesterday. And I just got done installing the new screen and the new camera /hearing piece/proximity sensor/and flash  ribbon, aggravating little things if you don’t hold your tongue just right.

But anyway turned it on and no screen response at all. I turned it off and back on by holding both buttons down and when it came back on it worked long enough for me to unlock the screen and change the desktop page and that was it. I didn’t get it to work since.

I haven’t took it back apart yet though I might see if yall had any ideas what to focus on inside. I changed everything from one phone back to the other and couldn’t tell ya what I changed but I did it just like the Youtube video and I thought everything went according to plan, no extra parts. The only thing I can figure maybe I put a screw that wasn’t the right size somewhere that didn’t tighten down all the way cause it was too long or not long enough. Can you point me in a direction to start at? Thank you  — Darinb41

Solution: Hi Darinb41. We can’t tell you where to focus as there’s a long list of possible reasons for the problem. The best thing that you can do right now is dismantle your phone once again and make sure that everything is in place, especially the connectors to the battery and to the logic board. You also want to inspect the power button and make sure that it’s not damaged. In other words, try to check the obvious components that can prevent the phone from booting. If you can’t figure it out, bring the phone to a service center so a professional can help you.

Problem #4: How to get files from a dead Galaxy S6

Hi. On the 12th Feb my S6 fell into the toilet and was then, unknowingly, urinated on! Once retrieved I immediately pressed the home key but the handset was unresponsive – pressed the power key but again nothing. So I sealed it in a container of rice for 4 nights. The power still wouldn’t come on so I then took it to a local phone repairer (regretfully, not Samsung authorized); it was returned after one week and I was told that the phone is dead. I’ve already got a replacement handset so my enquiry is not re the phone; what I’m DESPERATELY seeking is a way to retrieve the pictures and videos of my 1 year old daughter which I thought I’d backed up but have since discovered I hadn’t. Is there any way at all that I can get a chance of retrieving these? Best regards Abigail.

FYI my carrier is EE but I don’t know the android version. — Abigail

Solution: Hi Abigail. Unfortunately, there’s no way to access a Galaxy S6 phone’s internal storage device if you can’t turn the power back on. The Nand chip or the storage device of your phone, requires power the operating system can access its contents. If your phone is totally dead at this time, you’re out of luck.

Problem #5: Galaxy S6 reboots randomly

Hi, I have had my Galaxy S6 for a year and 7 months and I have loved it. On 6 March my phone had gone through a system update and it was good for a few days, but then I started to notice my battery draining faster than normal and at random times my phone would freeze and restart itself. Now, it will freeze and restart, but will not restart all the way and will just stay on the powered by Android start up screen and my LED blinker will show a blue and then fade into a lighter blue/almost white and go back to the other blue. I went to the Sprint store the other day and they hooked it up to some machine for an hour and did a factory reset, and they said I should be fine, but it kept doing the shutting off thing about an hour after I got it back from them. I am not sure if my phone is still on Marshmallow or if it updated to nougat. — Hannah

Solution: Hi Hannah. If the phone continues to shut down randomly after a factory reset, a hardware malfunction may be to blame. It can be a bad battery or an issue with the logic board so make sure that you have it checked by Samsung. If you can’t send it to a Samsung service center, try a good independent service to do the job.

Problem #6: Galaxy S6 messaging app very slow in sending SMS, keyboard app keeps lagging

My phone has been doing this weird thing where it shows that my message is still working on being sent for a while, but i guess it gets sent right away because people will respond but their response will post as if it went through before my message ever even sent. Sometimes it doesn’t matter but sometimes I’ll be having a conversation and get confused because i don’t know what message they are responding to because my phone shows them as if they went through later than i sent them.

Also sometimes the texting gets really slow…even typing? Can you please help!? I’ve had the phone for over a year so I’d rather not factory reset.  — Maria

Solution: Hi Maria. We recommend that first try app-level troubleshooting in this case. There may be a bug causing performance issue of the messaging app or the keyboard. To troubleshoot the involved apps, kindly do the steps below:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6.0.
  3. Once in there, click on an application.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the Clear Data and Clear Cache buttons for the application.

If the problem returns after wiping the cache and data of both messaging app and keyboard app, do a factory reset. Here’s how to do that:

  1. Turn off your Samsung Galaxy S6 Edge.
  2. Press and hold the Volume Up, Home and Power keys together.
  3. When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
  4. Wait until the Android Recovery Screen appears after about 30 seconds.
  5. Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
  6. Press the Volume Down button again until the option ‘Yes — delete all user data’ is highlighted and then press the Power key to select it.
  7. After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.

Problem #7: Galaxy S6 sends message to self when replying to MMS in group text

Hello. I have a problem with my Samsung Galaxy S6. When I send out an MMS message in a group text, the phone recognizes me as another person. So let say there are three people in the group text and I reply to something they mention. I send out my reply and I receive my reply back within seconds. Why? Who knows. But it just keeps happening. As well as regular SMS messages. The phone does not recognize my phone number and will assume that there three people in the message and I will receive my own reply back. Can you please help me? It’s very frustrating. Please. Thank you. Laura P.S. I don’t know if it makes a difference or not but the phone use to be Verizon. It’s unlocked and my service provider is AT&T. — Laura

Solution: Hi Laura. We don’t think this is an app-related issue so wiping the messaging app’s cache and data may not work at all. Nevertheless, we recommend that you try that first (refer to the steps above) to see any difference. If nothing changes, try to use another messaging app when sending and replying to a group message to see if it’s an issue with the current messaging app you’re using.

If using another messaging app won’t help either, talk to your carrier to see if they’ve heard of this problem.
