How to fix Samsung Galaxy S7 charging and texting issues that occurred after the Nougat update

Charging and texting issues are among the most common problems many Samsung Galaxy S7 owners encountered shortly after the Nougat update. While completely different, both of these issues are connected one way or the other since they occurred after the new firmware is installed.

Galaxy S7 not charging properly shortly after the Nougat update

Problem: Hi! I just updated to nougat on my Galaxy S7 and am having a problem with the charging.  It seems to stutter and cycle between “Charging” “Fast Charging” and then “Not Charging” for about 30 seconds before finally settling on “charging”.  However, if I pick up the phone to use it while it’s charging – the cycle will begin all over again. I’ve tested my phone on multiple chargers as well as multiple plugs so that is not the problem.  I can also say with 100% certainty I did not have this problem before installing the new software. Please let me know if you’ve heard of this problem or if you have any tips for how to fix it!  I’ve shut down and restarted the phone but no help.

Solution: If the device doesn’t have hardware problem, then most probably the newly installed firmware triggered it. In fact, when Nougat was first rolled out, a lot of users complained about several issues that occurred. But the good thing is that there are workarounds that you can do to help you fix the issue on your phone. On the other hand, if you downloaded an app prior or after the update that could be one of the factors to consider that the device function abnormally. To troubleshoot your device, here are the methods that you should do:

Step 1: There might be third-party apps that’s causing the issue

This method will help you identify if an app you downloaded from Play Store have something to do with the problem. In this mode, the third-party apps will be stopped from running in the system and if the issue is not anymore happening, then it should be one of your apps caused it. You can uninstall suspected apps one after another until the issue is fixed. And this is how you boot your phone in safe mode:

  1. Press and hold the Power key.
  2. As soon as you can see the ‘Samsung Galaxy S7 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: Wipe the cache partition of the device

Due to firmware update it is possible that the system cache became obsolete or geo corrupted and that’s the reason wiping the system cache is recommended especially after system update. Don’t you worry, this method won’t delete your  files and data stored on the device but rather it will force your phone to create newer caches that is compatible to the new system. Here’s how:

  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 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.

If the issue is not happening after the procedure, then obviously the system caches were corrupted or obsolete. But if the issue persists, you can proceed to the next step.

Step 3: Bring back your phone to its default settings

After booting the device in Safe mode and wiping off the system cache and the issue is still the same, then your last chance is to reset your phone. This procedure will delete everything so, backing up all your files and data stored on your phone is recommended. But the good thing is resetting will make your phone as good as when you first bought it and there is a big chance that the issue will be fixed after the procedure. Here are the steps that you need to do to reset your phone:

  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. 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 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.

Samsung Galaxy S7 text messaging (SMS) issue

Problem:My Samsung Galaxy S7 recently just got the newest phone update. Then just this morning I got a long text message that was converted into a multimedia message. At the bottom of the short version of the message, it says view all, I click view all and it goes to a new screen, but it doesn’t actually show the message. I tried restarting my phone, and clearing the cache and the data from the messaging app and nothing is working.

Solution: Since, you already delete the system cache but still no avail, then it might be a serious firmware issue. But before jumping to the conclusion the first thing that you should do is to know whether it is a firmware issue or just a downloaded app that complicates the device’s system. The purpose of this method is to identify if one of your apps is the culprit by stopping all of it from running in the system. So, while in Safe mode try sending a text message to your phone number and see if the problem is the same. If so, then you don’t have a choice but to reset your phone. Take note, that all stored files and data will be erased, so, before you proceed to the procedure try to backup all of it because you cannot retrieve all of it once you are done on the steps.

Moreover, you could also try turning on mobile data as it’s required to download necessary attachments. If it’s already enabled, try to check the APN settings to see if they conform with the settings of your carrier. Going through the Messages settings and making some chances where deemed necessary is also advisable.
