How to fix a Galaxy A5 that won’t connect to any public wifi [troubleshooting guide]

For those #GalaxyA5 users having trouble connecting to a particular wifi or, in this article, public wifi, this post should help. We understand that there’s a lot of people out there who can’t seem to get ideas what to do next if their phone fails to connect to wifi. We hope you’ll find this short guide and help you fix your  own wifi issue.

Problem #1: What to do if your Galaxy A5 is stuck on boot loop after Android Oreo update

Hello! I have got a Samsung A5 (2017) and a few days ago it did a automatic update to Android Oreo. After this update the phone could not start up and got stuck in a loop. After a few attempts and online chat contact with a samsung employee I decided to do a factory reset. After this, the phone had some issues starting up. It would need more than six tries before it came to the ´Hello´ screen and right away the pop ups showed that some apps crashed.This were no third party apps but apps from samsung itself, like´contacts´! After this I tried logging in with my google account but I couldn´t and I am really sure that the account is the right one. So I´ve tried starting the phone in safe mode. It is now in safe mode but right away a pop up screen showed up and says ´Start Samsung Experience stopped´. The phone is now frozen and doesn´t respond to anything at all. What do I do! Greetings.

Solution: If nothing positive comes out of factory reset thru Recovery Mode, you only have two options to choose from.

Roll back Android

Reverting Android to its previous version is not as easy as confirming a notification. It requires flashing or manually installing the firmware using a special tool called Odin. The entire process is called flashing in Android terminology. It’s also risky and can potentially cause more severe or permanent problems if not done correctly. If you haven’t heard of the term flashing before, consider yourself an amateur. We would discourage you from doing it. The same is true if you’ve heard of it before but you’re not confident that you can do it properly.

Flashing is only intended for internal Samsung use initially but when the Odin tool was leaked years back, genius Android users quickly spread the myth that flashing is the answer to Android problems. Unfortunately, that’s really not the case. Flashing a stock firmware can work in some limited situations. It may work in your case but we still advice you from doing it.

If you want to know more about how to flash your device, do more research about it yourself. Also, be sure to accept the risks involved should something goes wrong along the way.

Get Samsung support

This is the option that’s safe for most Android users. We understand how much hassle there is to live without a smartphone for days while waiting for it to be repaired. But unless you’re okay to have no phone at all for good, this should be the only option you should take.

No one, even Samsung, has any idea what exactly is happening on your device other than the obvious symptoms like being stuck on boot loop and all that. In order to understand the problem, a technician has to know the full history of your device. We can’t obviously have that so you the best option for you right now is to do some broad solutions, like reinstalling the operating system. And there’s no better people that can help you do that other than Samsung.

If going the Samsung route is impossible, let an experienced Android user try to flash the device for you.

Problem #2: How to fix a Galaxy A5 that won’t connect any public wifi

Hi. I have a Samsung Galaxy A5 phone which has been working brilliantly until a couple of weeks ago.  I then tried to log onto a particular Pub’s wifi (something I have done numerous times before) and instead of connecting, I got a message ‘The webpage at http://connectivitycheck.gstatic.com/generate_2014 could not be loaded because net:: ERR_PROXY_CONNECTION_FAILED appeared.  It then happened the next day at work on their wifi too (again, something I have connected to successfully numerous times). I have tried rebooting the phone & I regularly close down apps (using the button bottom left). It seems that it is trying to use Samsung Internet. What can I do to fix this?  I am not really ‘smartphone literate’. Thank you in advance.

Solution: Android devices sometimes fail to connect to certain wifi network due to an app issue or improper network configuration. To fix your problem, these are the possible solutions that you can try:

Forced reboot

Before doing any advanced troubleshooting, don’t forget to restart your phone. A lot of connection issues are fixed by simply turning off the device and restarting it. In your case, you want to force reboot your device by doing these steps:

  1. Press and hold the Power + Volume Down buttons for approximately 10 seconds or until the device power cycles. Allow several seconds for the Maintenance Boot Mode screen to appear.
  2. From the Maintenance Boot Mode screen, select Normal Boot. You can use the volume buttons to cycle through the available options and the lower left button (below the volume buttons) to select. Wait for up to 90 seconds for the reset to complete.

Cache partition wipe

Should a force reboot fail to fix the problem, the next troubleshooting step that you want to do is to see to it that you refresh the system cache. You can do that by clearing the cache partition where it’s stored. Here’s how:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  3. When the device logo screen displays, release only the Power key
  4. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times key to highlight ‘wipe cache partition.’
  6. Press the Power key to select.
  7. Press the Volume down key to highlight ‘yes’ and press the Power key to select.
  8. When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  9. Press the Power key to restart the device.

Reset app preferences

If nothing has worked at this point, the next good thing to do is to ensure that all of the default and necessary core system apps are enabled. Sometimes, an important app or service may be disabled. To ensure that that’s not the reason for your current problem, make sure that you reset all of your app preferences. Follow these steps:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap on More settings at the upper right (three-dot icon).
  4. Select Reset app preferences.
  5. Restart your A5 and check if you can now connect to the wifi networks you’re having an issue with.

Check for third party apps

To see if there’s a bad third party app blocking a wifi connection, try booting your phone to safe mode. To boot your A5 to safe mode:

  1. Turn the device off.
  2. Press and hold the Power key past the model name screen.
  3. When “SAMSUNG” appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see Safe Mode.
  8. Check for the problem.

Remember, if you are able to connect to wifi on safe mode but not when back to normal mode, it means one of your apps is causing it. To identify which of your apps is causing the trouble, you should boot the phone back to safe mode and follow these steps:

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your A5 is still problematic, repeat steps 1-4.

Reset network settings

If the problem is still unresolved at this point, you want to clear all network settings on your phone. This will return both cellular and wifi configurations back to their defaults. All previously connected wifi networks will be deleted in the process so be sure that you know the passwords ahead of time. Once ready, follow the steps below on how to clear your phone’s network:

  1. Open Settings app.
  2. Tap General management.
  3. Tap Reset.
  4. Tap Reset Network settings.
  5. Tap RESET SETTINGS button to confirm.
  6. Restart your S9 and check for the problem.

Factory reset

You’ll ultimately need to do a factory reset if all of the suggestions above won’t work. Remember, factory reset will wipe all data on your phone so be sure to back them up before doing it.

To factory reset your A5:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  7. Press Power button to select and start the master reset.
  8. When the master reset is complete, ‘Reboot system now’ is highlighted.
  9. Press the Power key to restart the device.
