How to troubleshoot Galaxy S7 Edge that slowed down after the Nougat update

Problem: Nougat is supposed to make my phone faster, right? Such is the purpose of updating the firmware aside from security patches. However, my Galaxy S7 Edge seems to have slowed down noticeably after I downloaded the Nougat update. It’s not the first time that I updated this phone so I know that this time the update seems to have failed to improve my phone’s performance, which is really bad since I’ve been expecting it to even make it better. Powerful as it may seem, my phone not takes forever to open my email or text messages. What shall I do?

Troubleshooting: There are a lot of factors we need to consider when troubleshooting this kind of problem. However, we have to consider first that this problem occurred shortly after the Nougat update, which means that it could totally be just a firmware issue since Nougat is a major update and many of the cache and data may not be compatible with the new system anymore. There are a couple of procedures I want you to do, so continue reading below:

Step 1: Reboots your phone in Safe Mode to see if it becomes faster

Obviously, this is not the fix but it will give us an idea to know whether the problem is with your third-party apps or not. If the former have something to do with the slowing down of your phone, then you just have to find the culprits and uninstall them and probably download new versions of those apps again. However, if the problem still persists even in safe mode, then it must be the firmware that we have to look into. Here’s how you boot your S7 Edge 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.

I am hoping that this problem is not as serious as it seems and can only be fixed by uninstalling some apps. However, if the issue is with the firmware, then the next step should take care of it.

Step 2: Backup your data and do the Master Reset

I understand the phone is so slow and it might take forever to backup everything in it but please try, at least, salvage your important files first because one the reset is done, they will be deleted and can no longer be retrieved. After the backup, do this procedure:

  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.

I hope this helps.

How to troubleshoot your Galaxy S7 Edge that started to freeze randomly after the update

Problem: What are you guys going to do if your phone starts to randomly freeze while you’re using it? I have the Samsung Galaxy S7 Edge and it freezes whenever I use it but honestly, I don’t know if it also freezes when idle. When I’m using it and while I’m in some apps, it would start to freeze at will. Sometimes the freeze will take a minute or two and sometimes just a matter of seconds but very annoying nonetheless. So if you guys can help me out a bit here, that would be great. Thanks.

The Samsung Galaxy S7 Edge is an impressive device in terms of specs and performance, but that will be gone if there are several apps running at the same time, especially the heavy one. To experience the performance that you wanted to see in your device, it is best advice to close those unnecessary apps right after you use it. If you are playing and the same time your chrome browser is running at the background, it will affect the performance gravely, since browsers sometimes can use a lot of memory.

Now, speaking memory, keeping the memory usage at normal level is best advice. If it will reach to a critical level, it will start to lag or freeze. There are apps and services are running in the background that you won’t notice because there’s no level indicator displayed. The applications that mostly using a lot of memory are games (online), browsers, anti-virus, third-party apps (auto-update on), etc..

The apps that turns on the auto-update are the ones using a lot of RAM, it would be frustrating to close the apps everytime after using it. So, turning off the auto-update is the solution for that issue. You will need to go to the Google play store to successfully turn off the auto-update. It’s not only improving your device performance, it will also makes your battery life longer. Here’s how to turn off the auto-update:

  7. Choose “Do not auto-update apps”, tap it
  8. Go back to Home screen

NOTE: Even though it was turned off, you will still get a notification that a new update is available.

Clear System Cache Partition

In case turning off the auto-update didn’t resolve the issue, then you can proceed and clear the system cache partition. This procedure will clear all cached files used by frequently used apps, old system temporary files, and others that uses a cache files. It will force the system to create a new file that is compatible to the new update.

How to troubleshoot Galaxy S7 Edge that started to lag after a firmware update

Problem: I know that lagging is never normal with my phone, which is a Galaxy S7 Edge. I bought this phone brand new last year and I know how fast it could execute my commands, however, just recently, there was an update that I of course downloaded and i think it was successful as there were no errors whatsoever. But the problem is that the phone started to lag anytime of the day regardless what I’m doing. When it occurs, it’s basically very slow that it takes so long for it to open apps and there are even instances where it just freeze for a few seconds and then goes back to the lagging. I’m not really sure what to do since this is the first time that it occurred. Can you help?

Troubleshooting: Since, the device had not been dropped or soaked in the water then most likely it is a firmware related issue. We understand that you have lots of important files stored on your phone and you don’t want to delete all of it. So, in this instance you need to perform the basic troubleshooting procedures on your device and observe if the issue will be fixed. The first thing that we want you to do is to boot your phone in Safe mode.

There are two types of apps on your device the pre-installed and third-party apps. The main purpose of this procedure is to identify what caused the issue whether third-party or pre-installed apps. So, while booting it on safe mode try to observe if the issue persists. Remember that while in this mode all third-party apps will be disabled and if the issue is not happening, then most likely one of your apps is the culprit. Try to uninstall those suspected apps and see if the device will still shut’s off.

However, if the issue still happening while in Safe mode you can perform the next procedure by deleting the system cache on your phone. Caches are temporary files stored in your device to make it run smoothly, so, if that old caches was corrupted after the update that might be the reason that your phone shuts off randomly. To delete the system cache, just follow the steps provided above.

But after all the procedures and still no avail on the issue, then you can perform the more complicated procedure by performing reset on your phone. But before doing so, you need to backup or copy all your files on your phone and transferred over to your SD card or computer because all of it will be deleted once you will perform this procedure.

  1. 3 very annoying things after Nougat upgrade to firmware on my Samsung Galaxy S7 Edge:

    1) Photos take a second or two to focus very sharp. A bit like the old slow Samsung phones used to work with photos.

    2) In the Gallery APP from Samsung the Album preview now has heads cut off instead of showing the full photo. Most annoying.

    3) When charging, the unit says 100% charged but the red LED stays on instead of colour change when fully charged like be4.

    Does Samsung not want happy customers? I downloaded the 23 Meg update but can not really see what it fixed. Certainly not the problems I am having now 🙁

    Come on Samsung – this smartphone was bought outright and cost a lot of money. It worked lovely be4 Nougat. How about a full fix and also for the problems I am experiencing with photos and the LED charging indication.

  2. Two days after the upgrade my Samsung Galaxy S7 stopped working. I do hold Power button but nothing pops-up. to remind, there is no access to remove battery. Screen hangs, nothing happens. Shall I wait for two days until my battery dies or there is another way to reboot the phone? I am expecting VERY important calls
