Galaxy S7 Edge not charging after an update

It seldom occurs that a firmware update can result to a not charging issue but it could happen. The thing about it is that it’s not entirely an issue with the firmware, in fact, we don’t know for sure if the new system has something to do with it. Here’s one of the messages we received from our readers that best describes it:

Hi guys! I have the new Galaxy S7 Edge that was working fine and got no issues. When the update came, it stopped charging. When I plug it in, the phone just won’t respond to it. Normally, there’s a light that will be lit up and the charging icon would show. Can you guys look into this?

Usually, when we troubleshoot not charging issues like this, we go straight to the accessories and the hardware, i.e. charger, USB cable, utility port, battery, etc. However, in this case, we need to rule out the possibility that the recent update messed up the phone. That said, the very first thing you should do is delete the system cache as it often gets corrupted.

  1. Turn off your Samsung Galaxy S7 Edge.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 Edge 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 wiping the partition. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

If the problem remains and your phone still has enough battery to backup your data and perform the master reset, then you should do it:

  1. Turn off your Samsung Galaxy S7 Edge.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.

NOTE: It doesn’t matter how long you press and hold the Home and Volume Up keys, it won’t affect the phone but by the time you press and hold the Power key, that’s when the phone starts to respond.

  1. When the Samsung Galaxy S7 Edge shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  2. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.

NOTE: The “Installing system update” message may show on the screen for several seconds before displaying the Android system recovery menu. This is just the first phase of the entire process.

  1. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  2. Once highlighted, you may press the Power key to select it.
  3. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  4. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  5. The phone will now reboot longer than usual.

If the reset failed as well, then it’s time you went after the accessories first and then the hardware.

Step 1: Troubleshoot the charger or power adapter you’re using. You don’t have to open it, you just have to look into the port to see if there’s a lint or debris that’s preventing proper contacts between receptors. The best way to check if it’s the charger is by using a different one. If the phone charges with other chargers, then you know what to do.

Step 2: Check the USB cable for some breakage. Just run your fingers through it to see if you can feel a lump that’s an indication something is not right beneath the cover. Whether you can feel something or not, it’s also wise to use a different cable. If it’s the problem, you can buy just the cable or you can buy a new charger, which comes with a cable.

Step 3: Check the USB or utility port of your phone. Just like how you inspect the charger, try to see if there are debris and lint in it. Also, take into consideration the possibility that a pin may have been bent. For debris, you can remove them with a blast of compressed air or by using a toothpick. If one of the pins is bent, you can actually straighten it out using a toothpick. After you’ve check it, try to plug your phone and hold it at a certain angle. If the phone charges if held a certain angle, then it’s a loose connection and you need a technician to fix it for you.

Step 4: Seek help from a technician. You’ve done what you need to do so if the problem remained after everything, you need someone who can open the phone up and perform further tests.

Galaxy S7 Edge started to charge very slow

Slow charging issues are very common and more often than not, they are firmware- and app-related problems. It is imperative that you take one step at a time in troubleshooting this issue as it may just save you from a lot of trouble. That said, here’s what you need to do:

TDG guys, I hope you can really help me. For some reason my Galaxy S7 Edge started to charge very slow, which is a big turn off considering I bought this phone because if its fast charging feature. Now, it takes more than five hours to reach 85% from 10% and it just can’t complete it. What gives?

Step 1: First and foremost, boot your device in safe mode. It is necessary to isolate the issue to know if downloaded apps have something to do with it. If the phone charges fine in safe mode, then our suspicion is confirmed, otherwise, do the next procedure to probe further.

  1. Press and hold the Power key.
  2. As soon as you can see the ‘Samsung Galaxy S7 EDGE’ on the screen, release the Power key and immediately hold the Volume Down key.
  3. Continue holding the Volume Down button until the device finishes rebooting.
  4. You may release it when you can see ‘Safe mode’ in the bottom left corner of the screen.

Step 2: Turn your Galaxy S7 Edge off and plug it in to charge. This is another way to test if your phone charges normally when everything is powered off because if so, then the problem is undeniably with the firmware. In this case, you can proceed with the wiping of the cache partition and/or doing the master reset. Please refer to the instructions above.

Step 3: Send the phone in for further checkup and repair. In case the reset didn’t fix the problem, then it must be a hardware problem and you can’t do something about it except find a technician to take care of it for you.

Galaxy S7 Edge won’t turn back on after it shutdown due to battery drain

System crashes are very common and they occur without apparent reason. Fortunately, this issue can easily be fixed, in fact, all you got to do is force reboot your phone. Here’s the actual message we received from our reader:

I got my S7 Edge about a month ago and so far so good. Last night I was with friends and I got the battery empty so the phone turned off. I connected the charger and it charged fine. I didn’t try to turn it on until it was in 20% but when I did, it just won’t turn on. So, I unplugged the phone and tried again, still nothing. When I plugged it again, it won’t charge anymore. What happened to it? Does this mean I broke my phone just by charging it? Help me please. Thanks.

It happens all the time that the phone crashes during boot up especially if some services failed to load. It’s nothing serious, actually. All you got to do is press and hold the Volume Down button and the Power key together for 10 seconds to reboot the phone. I believe just this procedure along can fix this problem as nothing significant actually happened that could have led to this issue.

Galaxy S7 Edge won’t charge after taking photo under water

The following issue is apparently caused by water and when it comes to this thing, there’s not much we can do about it. To give you a clearer picture how this issue happens, here’s the actual message from our readers:

Let me tell you in detail how this problem started. I had to go with friends to the beach and I had my S7 Edge fully charged the night before. We took some pictures while taking shower in plain water and the phone has been working fine after that. Then we took some pictures while swimming in the sea and we were actually able to take more than 30 shots. About a couple of hours after taking pictures, the phone’s screen started to flicker then it rebooted on its own once. It drained its battery a bit quicker than expected and when I plugged it, it just won’t charge. Is it possible that water ruined it? It’s supposed to be waterproof, why is this happening?

If this happens to you, have your phone powered off and don’t charge it again. Then send it in so the technician can clean and dry it out before turning it on again. At this point, everything depends on the skill of the technician that handles the case.
