Problem: Samsung Galaxy A5 (2017) keeps restarting when wifi is on

Hi. I have a Samsung A5 2017 and my problem is that yesterday it started to act funny out of nowhere. I was using it in the morning and then all of a sudden the wifi turned itself off. I tried to turn it on again over and over but it would load then switch back to off. It then started to restart itself again and again. I did a factory reset but the problem is still there – the resetting doesn’t seem to be as bad but it still happens. More so if I try to turn the wifi back on again. Is there any advice you can give to fix it or do I just have to give it to someone to repair – is it even something you can repair? And how would I be able to avoid this in future? Thank you.

Solution: Frankly, there’s no way for us to know for sure what’s wrong with your phone or what causes the problem. We need more information than what you provide here in order to understand better the situation. Since you did not mention ever dropping the phone or physically impacting it, we assume it’s in good shape and there’s no hardware defect at all. That means that the reason for the problem must be software-related. If that’s the case, any of the solutions below should help.

Install updates

To lessen chances of bugs from developing, you want to make sure that your Galaxy A5 runs the latest app and Android versions. By default, your device should download app and Android updates on its own. However, you can also manually check for any available updates by either going thru Play Store (for app updates) or by checking Settings > Software update (for Android or carrier updates).

Some network bugs are only fixable by installing carrier updates. If your experience is the result or poor or inefficient firmware coding and it’s been reported, your carrier may release an update to address it.

Observe on Safe Mode

Sometimes, a third party app may interfere with the operating system and cause problems. To check if what you’re experiencing is due to a bad third party app, restart the phone to safe mode and let it run for a few hours. This should give you enough time to see if there’s a difference. To restart your phone 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.

If your device works normally on safe mode but becomes problematic again when restarted to normal mode, that’s an app problem. 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 device is still problematic, repeat steps 1-4.

Reset network settings

Whenever there’s a network problem, one of the basic things to do is to reset the network settings. You will need to do this if your phone has some issues connecting to networks or other devices. When it’s done, the following changes will occur by performing a reset of network settings.

  • Stored Wi-Fi networks will be deleted.
  • Paired Bluetooth devices will be deleted.
  • Background data sync settings will be turned on.
  • Data restrictive settings in applications that were manually turned on/off by the customer will be reset to the default setting.
  • Network selection mode will be set to automatic.

Only the mobile data will be left enabled once its done so you will need to enable Wifi if you want to connect to a hotspot in your area. Here’s how to reset network settings in your phone…

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap Settings > General Management > Reset > Reset network settings.
  3. Tap RESET SETTINGS.
  4. If you have set up a PIN, enter it.
  5. Tap RESET SETTINGS. Once complete, a confirmation window will appear.

Reset all settings

Clearing of network settings should be followed by resetting of all settings should nothing work. This is useful if you previously tried to tweak some system settings and you don’t know how to return them to their defaults.

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap Settings > General Management > Reset > Reset settings.
  3. Tap RESET SETTINGS.
  4. If you have set up a PIN, enter it.
  5. Tap RESET SETTINGS.
  6. The device will restart to perform the reset of settings.

Factory reset

If the problem returns after doing all the suggestions above, you should wipe the device and return all its software settings to their defaults. Make sure to create a backup of your data before doing so.

  1. Create a backup of your data.
  2. Turn off the device.
  3. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  4. 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).
  5. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.
