How to fix Galaxy S7 Edge that doesn’t charge properly after the Nougat update [Troubleshooting Guide]

Performance and power related issues are among the most common problems any smartphone owner might complain about. However, in the case of some of our readers who own a Samsung Galaxy S7 Edge, it seems like the problem started after the most recent Nougat update.

This, of course, left us thinking that may be the problem is due to some issues with the firmware itself, which includes corrupt system files due to interrupted download or obsolete system caches. In short, we don’t know why the phone no longer charges properly after its firmware has been updated to Nougat. That is why it is imperative we try to troubleshoot your device to know exactly what caused it not to charge properly anymore.

If you own a Samsung Galaxy S7 Edge and are currently bugged by a similar problem, then read on to understand why these kinds of problem happen in the first place and learn what needs to be done in order to fix the problem.

All other problems I tackled here either started without any cause or after a firmware update.

Galaxy S7 Edge charges intermittently after Nougat update

Problem: After update, when plugged into charger, the charging intermittently starts and stops forever. This only happens when my phone is turned on. When I turn it off and plug it in, it charges normally.

Solution: If the problem started after system update, then the firmware might had been messed up or the battery itself is defective. On the other hand, if you downloaded an app from Play Store prior the update was made that could be one of the factors why the issue is happening. So, to isolate the problem all you need to do is to perform the basic troubleshooting procedures and observe closely if there are changes on the performance of your phone. Here are the procedures that you should do:

Step 1: Connect it to the charger to check if the battery is not defective

Usually, due to battery malfunction users assume that the device has a firmware issue not knowing it is just a battery problem. In this method, we have to check if the battery is defective or not by connecting the device to the charger. So, while in this state let the device charge for 15-20 minutes and see if it is responding. But if the device is not charging, bring it to the nearest shop in your area and let the technician check it for you.

Step 2: Force reboot the device

Assuming that the device is charging properly, this time try to check if it is just a glitch in the system by pressing and holding the Power and Volume Down keys at the same time for 10-15 seconds and wait until the device reboots. If your phone turned on, then obviously it is a glitch in the system. However, if the problem persists after the procedure you can proceed to the next step.

Step 3: Restart in Safe mode

This method is an Android environment wherein the third-party apps will be stopped from running in the system. Through this, we can identify if one of your downloaded applications is culprit and triggered the issue. If that’s the case try to uninstall every suspected app until the device performance will back to normal. Here’s how to boot your phone in Safe mode:

  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.

If the phone charges while in this mode, then it’s confirmed that the problem is due to one or some of your third-party apps. Find that app and then clear its cache and data and if that won’t work, uninstall it.

  1. From the Home screen, tap the Apps icon.
  2. Find and tap on Settings.
  3. Touch Applications and then Application manager.
  4. Swipe to ALL tab.
  5. Find and touch suspected.
  6. Tap Storage.
  7. Tap Clear cache and then Clear data, Delete.

You may need to do this to all other suspected apps until the problem is fixed. To uninstall an app, just follow the same procedure but hit uninstall instead.

Step 4:Wipe the System cache of the phone

Although we are not sure what caused the issue to occur, it is imperative that the cache directory of the phone should be cleared out especially after a firmware update. There are two types of caches your phone have; the apps caches, which are created by the apps themselves and the system cache, created by the firmware. But if those caches were corrupted there is a possibility that the firmware could not function normally, so, through deleting it the device could create newer caches that could run smoothly in the system. Here’s how to delete the system cache of the device:

  1. Turn off the phone.
  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 cache partition. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

So, after performing the procedure connect your phone to the charger and observe if the issue occurs. If so, you can proceed to the next step for further troubleshooting.

Step 5: Bring back the device to its default settings

If the battery is fine and the procedures don’t fix the issue, then your last resort is to reset your phone. However, before following the steps make sure you transfer all files to your SD card or to your personal computer because all will be erased and cannot retrieve it. Here’s how to do:

  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.
  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. 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.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes — delete all user data’ 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.

Galaxy S7 Edge stopped charging and no longer turns on

Problem: Hi I have a Samsung Galaxy S7 edge.  My phone starts to have problem after it updates to android 7.0.  First, it was flashing green and blank/white screen.  After I did a factory reset, it flashed green screen when it was in the lock screen and the screen kept on flickering on any other screens/apps.  The same issues happened in safe mode.  I couldn’t get into the recovery because it also stopped showing the “Samsung Galaxy S7 edge” screen, so I didn’t know when to release the power button.  Now, it stopped charging and wouldn’t turn on.  Is there a fix to this?

Solution: As you stated that the problem occurred after system update, then there is a chance that the issue will be fixed. The first thing that you should do is to do the forced reboot procedure to figure it out if it is a glitch in the system. But if the problem persists, try to use another charger and leave it for 15-20 minutes and observe if the device responds. If not, then obviously the battery is defective and that would be the reason that your phone cannot boot up completely.

On the other hand, if the device responds the next thing that you should do is to wipe the cache partition ( just follow the procedures above) of the phone to delete those all old caches stored in the cache directory. But if all those procedures failed to fix the issue, you can bring your device to the nearest shop in your area and let the technician check it for it might be a hardware issue.
