Problem #1: Water-damaged Galaxy S7 won’t charge

So I’ve had my Samsung Galaxy S7 for quite a few months now and I’ve always known that it’s water resistant. I’m still an adolescent so my parents pay for my phone (so I can’t really go anywhere to get my phone checked out and make my parents pay even more seeing as I’m on a plan with my 3 siblings and my mother and my phone alone is about $650/month, if I remember correctly). I’m a bit of a…neat freak but not neat freak like I have a organized mess in my room (yes this has to do with it) and even if something isn’t clean as long as it feels clean to me I’m ok (like i may wash my hands a few times, or even rinse my hands even though all the germs aren’t gone). Yeah, I’m kind of weird. Anyway, I’ll connect the dots now so you can follow my train of thought.

So because I know that my phone is water resistant and all and because once when it fell in the toilet I washed it with soap and water and it didn’t mess up, when I feel or my phone looks dirty I wash it. In this case I rinsed it and after I did, I realized that it was about to die, like at 12% (I know you usually have to let it dry to charge it) but I rarely let my phone die. you know “this generation never gets off their phones” etc. Well yeah, I rarely let my phone die so I used a blow dryer. I wasn’t sure it was ok to blow dry it, until I was looking on this website and saw that it was, so I first put it at medium power and at “cool” but it wasn’t quick enough, so I left it at medium power but changed the temperature to “warm”. It still didn’t help (this was the first time I ever need to charge my phone after washing it and I do realize that I should have just let it dry and die…or turn it off (but I didn’t know this would happen so I didn’t). And I tried different chargers, outlets, moving my charger AND my phone in different angles but nothing worked. I think i did a soft reboot but I’m not really sure (looked up how to online) because my phone died and if a soft reboot would’ve work. then I didn’t because it still didn’t charge after dying. Oh and I tried my best to make sure no debris was in my charger port and on my charger. And also for a split second it responded to me changing to a different outlet but it disappeared like in the beginning when it was responding every few seconds (off and on) getting worst with time. In the beginning it wasn’t charging due to water in the port but then it just wasn’t charging and yes this is the original charger and cord.

Also I checked for water damage (I read how to on this website I think) and that wasn’t the case. In the past the only problem I had was my phone randomly turning off when I first woke up and took it off the charger but that problem only really lasted about a week then it went away. Please help. Soon I start school tomorrow and really can’t survive without my phone/music….I know y’all probably won’t reply by tomorrow but yea please hurry. Thank you and sorry for this long paragraph and how my thoughts are a bit scattered and no this was not proofread so sorry. — Esther

Solution: Hi Esther. While Samsung’s latest flagship is IP68 certified, which means that it has dust proof protection and water resistance for over 1.5 meter for over 30 minutes, it doesn’t mean that the phone is fully water proof. Keep in mind that the added layer of water resistance may not work if you move the phone through water, or if you subject the device to high-pressure water source like faucets. Dropping a Galaxy S7 into a pool, toilet, or sea water can create unnecessary pressure around the device’s vulnerable ports (headphone jacks, speaker box, charging port) making water resistance protection useless. The general rule when dealing with possible water damage issue is simple — if issues occur after water exposure, you must assume that some hardware component must be affected. If the charging issue happened after you dropped your phone to water or liquid, the best thing that you can do right now is to have the phone’s hardware checked. That may be difficult given the financial situation you’re in, but this is the only way to arrive at a permanent fix. Unless you have the necessary skill set and tools, we highly discourage you to do a do-it-yourself repair. Water damage can result to all sorts of hardware issues so you need to use a number of electronics tools to check if every component is working normally.

If you have access to a nearby Samsung service center, we recommend that you bring your phone there so it can be checked. Water damage constitutes user mishandling so it automatically voids the device’s warranty but letting Samsung do the potential repair is way better than having a third party shop do it.

Problem #2: Galaxy S7 won’t connect to the internet via wifi and mobile data

My Samsung Galaxy S7 will not connect to the internet. It doesn’t matter if I go through my home WiFi or through the network, either way it’s not working. I have tried rebooting – many times – with no improvement. I have also tried shutting down completely for about half an hour before powering back up, but that did not help, either. Given the model of the phone, I cannot drop the battery out of it as I have no battery access. The phone’s attempts to connect with the internet have been rapidly draining the battery. It has occurred to me to see if letting the battery run completely down would help, but I’d like to keep trying other options as well. This problem started late last night. I made no changes to the phone at that time – no new apps or configurations. The most recent app I’ve added was a Cub Foods member app, and that was a couple weeks ago. There was an Android update this morning, but since the problem started last night, I don’t think that’s the cause. I’ve tried searching solutions online, but have yet to find anything helpful to me. Any suggestions would be very welcome. Thank you! — Alison

Solution: Hi Alison. The first thing that you want to do here is to check if the problem is caused by third party apps. This is done by booting the phone to safe mode. Safe mode blocks third party apps and services from running so it’s a good way to see if something changes when it’s enabled. Basically, safe mode helps you by using simple comparative analysis; if the issue won’t occur while it is on, then one of the apps must be to blame. In order to boot the phone to safe mode, follow these steps:

      1. Turn your Galaxy S7 off.
      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. Observe the phone for a few hours to see any difference.

    If the issue remains while safe mode is enabled, a good old factory reset may help. When you factory reset a phone, all software settings are restored to their known, working state, at the same time deleting all user-introduced changes from the device. In other words, factory reset reverts all software settings to stock condition. If the issue persists even right after a factory reset, that should tell you that the reason for the problem does not lie on the software but rather on the hardware department. If you think bad hardware is to blame, you must find a way to have the unit replaced.

    For reference, below are the steps on how to factory reset your S7:

        1. Create a back up of your irreplaceable files.
        2. Turn off your Samsung Galaxy S7.
        3. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
        4. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
        5. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
        6. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
        7. Once highlighted, you may press the Power key to select it.
        8. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
        9. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
        10. The phone will now reboot longer than usual.

      Problem #3: Galaxy S7 slow in sending SMS | Galaxy S7 “Unfortunately, Messenger has stopped” error

      I own a Samsung Galaxy S7 through AT&T. All was fine until recently, when texting one of my close friends (we have been messaging a long time before with no problems) the texts that are long enough will not come in as one message, but rather be separated into little messages. I also notice that when I hit send, the sending animation is not smooth and will often not show the message “sliding” from the input box to the sent area. It will rather momentarily freeze and the sent message will just appear. (Not a big deal, just included for completeness). On top of that, if I am typing a message in response, and my friend sends another message, the messaging app will crash with an error message reading: “Unfortunately, Messenger has stopped.” The message I was typing is completely lost and not saved as a draft either. What is most unusual is that this problem only occurs when texting this specific person. For completeness, my friend uses an iPhone 6 through Sprint. — Jbinkowski8

      Solution: Hi Jbinkowski8. The cause of the problem may be a bug in the system cache or the messaging app  so the first thing that you want to do is to wipe the cache partition. Installing system updates and apps can sometimes corrupt the system cache, which, in turn, can lead to all sorts of problems. To fix the issue, simply wipe the cache partition in order to refresh the system cache. Here’s how:

          1. Turn off your Samsung Galaxy S7.
          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. Once highlighted, you may press the Power key to select it.
          7. Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
          8. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
          9. The phone will now reboot longer than usual.

        If the problem remains, you can also wipe the messaging app’s cache and data. Here’s how:

            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.

          Any of these two processes should fix the problem but should the issue continues, don’t hesitate to do a factory reset.

          Problem #4: Galaxy S7 showing battery overheating sign when charging

          Hi! Over the last two days or so, the charging hasn’t been very efficient even with the fast charger. I tried multiple cords and blocks and also a portable charger. Just now, my phone died while i was on video chat and I plugged it in and it says it’s fast charging now but when i go to turn it on, it blinks a thermometer at me which I’m guessing, means the battery is overheating again, but the phone actually feels cold. I’m not able to do the soft reset as i don’t have the tools to remove the back of my edge. Is there anything else i can do? Many thanks! — Emma

          Solution: Hi Emma. If the phone shows the overheating battery sign when it’s connected to a charger, the problem may lie on the battery itself. If you want to try soft reset or the equivalent of a “battery pull” follow these steps:

              • Press and hold the Power (located on the right edge) and Volume down buttons (located on the left edge) for 12 seconds.
              • Use the Volume down button to scroll to the Power Down option.
              • Press the Home key to select.

              Keep in mind that your phone may not turn on at all if the battery level during soft reset is below 5%. If you won’t be able to turn the phone back on because of this reason, try charging the phone using another Samsung charger. If it flashes the battery overheating sign once more, consider using a wireless charger. Using a wireless charger is obviously not a permanent fix so you should consider having the phone checked by Samsung so they can examine if the issue lies on the charging port or the battery.

              Problem #5: Galaxy S7 won’t connect to Bluetooth speaker

              I have a Galaxy S7 that has worked well since I purchased it. The bluetooth started malfunctioning by going on and off and telling me that ‘unfortunately bluetooth share has stopped.” This did not happen all the time. Then it stopped scanning for new devices, which I learned in a rental car when the phone couldn’t find the car. Then it stopped pairing with my small home bluetooth speaker, which seems to work with other phones.

              Tried to hook up phone to home speaker, which was already paired, but it would not connect. I read on-line that I should clear the cache, which I did, as well as the data. I also read that I should un-pair, but the speaker disappeared from the phone altogether, and now it won’t scan for new pairings at all. I press on ‘pair’, and it does not scan. At all.

              I really need Bluetooth in my car. Is there any hope? And while you’re helping me, if I were to buy a new phone, which do you recommend as being the most problem-free? I have an iPhone for work, and much prefer the Galaxy phone for my personal use.

              Thank you so much, I’ve been admiring your efforts for a long time and subscribe to your emails. — Lesley

              Solution: Hi Leyley. When faced with Bluetooth-related issue, there’s usually a need to troubleshoot not just the phone but also the other device. Bluetooth connection is a two-way street so you must consider both sides in order to arrive at a solution. In your case, there’s a chance that the problem may not be on your phone at all but rather on the other device that you’re trying to pair with it. As far as troubleshooting the phone is concerned, the most effective step that you can always do is factory reset. This will force all software settings back to their factory state. If a bug has been introduced during the course of your normal usage, factory reset should eliminate it. Assuming that the other device is compatible with your S7’s Bluetooth version, re-pairing both devices should work. If pairing won’t work still even after you’ve factory reset your phone, the issue must be on the other device. Bluetooth system, like Android, is constantly evolving so there’s a chance that incompatibility can play a role. Keep in mind that smartphones regularly receive more updates for Bluetooth than “older” versions like those in car kit systems. Put simply, you must also ensure that the other device you’re trying to pair with your phone is running the latest Bluetooth versions.

              If I were to buy a new phone, which do you recommend as being the most problem-free? We don’t want to give a particular brand or model but if you can afford the latest flagship phone from any major Android manufacturers, grab one.

              Problem #6: Galaxy S7 wifi won’t turn on

              Hello Droidguy. My name is Nana and I saw your article about wifi which are not able to turn on. I am using an S7 which has this problem since I started using it. One day,  I noticed that the wifi has turned on and I was very happy about that. I turned it on and off several times to confirm that it has started working alright and it was. About four days later, when I turned on the wifi, I noticed it has malfunctioned again as it was at first. Attached are screen shots I snapped when it started working alright. When I turn it on now, it looks as if its turning on then it goes off. I want to bring this problem to your attention since you are the Droidguy so that you can assist me with a solution. I look forward to a solution. Regards. — Nana

              Solution: Hi Nana. Like most Android issues, your problem can be caused by a software or app glitch or by bad hardware. We recommend that you try all relevant software troubleshooting for your case like wiping the cache partition, observing in safe mode, and factory reset. If they won’t help improve the situation, then you can assume that there must be a hardware issue somewhere. It can be a bad wifi antenna or other unknown parts. In this case, you want to consider repair or replacement.
