Below are specific topics we’re bringing for you today:

Problem 1: Galaxy Note 5 can’t open some links from different websites

When I am on a website and wish to connect from a link on that website I get either some sort of error message or unable to connect message. Example, from Book Bub there is a link to Amazon books that will not connect. This is not the only example, it happens at other times on other websites. I have no idea what is going on. Can you help me? — David Thomas

Solution: Hi David. If this problem occurs when using one particular browser or app only, for example the stock browser named Internet, it’s possible that there’s a bug behind it. To fix the problem, you can do the troubleshooting steps below:

Force restart the phone

This procedure is similar to a restart in a desktop computer. It will force the phone to reboot thereby refreshing the system. If you haven’t tried it before, just press and hold the Volume Down and Power buttons for at least 12 seconds. Once the phone starts to restart, let the buttons go.

This procedure is an effective solution for problems like yours and others that include the following:

  1. Frozen phone
  2. Unresponsive device
  3. Very sluggish performance due to constant freezing
  4. Unresponsive due to app crashes
  5. Got stuck during boot up and became unresponsive, etc.

Delete app cache and/or data

If restarting your phone won’t fix the problem, the next good thing to do is to deal with the app directly by first clearing its cache, then clearing its data. Here’s how:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to Apps. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
  3. Once in there, look for the application you’re having a problem with and tap it.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. Tap Clear Cache.
  6. Restart the phone.
  7. Check if the problem returns.
  8. Repeat steps 1-4.
  9. Tap Clear Data.
  10. Restart the phone.
  11. Check if the problem returns.

Use a different app

If the problem remains at this point, there’s a chance that there may be a coding bug in the app you’re using. Consider using a similar app and see how it goes. For example, you may want to consider using Google Chrome or Firefox for Android to test it out.

Problem 2: Galaxy Note 5 wifi keeps disconnecting after a minute

I bought a new Samsung note 5 smartphone six weeks ago and it was fine. Then I had a new wifi router and service provider installed it last week. Since then the phone will only connect to the Internet for approximately one minute, then you have to switch off/on the wifi on the phone and it will then connect again for a minute.

The phone is connected to the wifi because whatsapp is working perfectly. It is an issue with the connectivity of the Internet to the new router. I tried switching the router on and off, switching the wifi on the phone on/off, factory reset on the phone, makes no difference. If you can any suggestions I would be grateful. Thank you. — David Griffiths

Solution: Hi David. This type of issue can’t only come from your phone. There’s a chance that it’s caused by the router as well so you need to do some diagnostics.

Restart the phone

Restart can sometimes work wonders. Be sure to refresh the system by force rebooting it. Refer to the steps above on how to do it.

Forget, then reconnect to the network

There may be a wifi service bug causing the problem so you need to disconnect from the network by doing the following steps:

  1. Open Settings app.
  2. Tap Connections.
  3. Press and hold Wi-Fi.
  4. Tap the name of your wifi network.
  5. Tap Forget.
  6. Restart the phone.
  7. Connect to your wifi network again.

Check for third party app interference

An issue like this can also be caused by a bad third party app so checking is an important step. To do that, you need to restart the phone to safe mode. In this mode, all third party apps and services will be blocked. If wifi works normally when your phone is in safe mode, that’s a sure indication that you have one bad app causing the problem.

To restart to safe mode, follow these steps:

  1. Turn off the phone completely.
  2. Press and hold the Power key.
  3. Once ‘Samsung Galaxy Note5’ shows, release the Power key and immediately press and hold the Volume Down button.
  4. The phone will restart but keep the Vol Down button pressed.
  5. Once the phone has finished restarting, ‘Safe mode’ will be display in the lower-left corner of the screen.
  6. You may now release the Volume Down button.

Safe mode won’t help you pinpoint the problematic app. To do that, you need to use elimination process by uninstalling and observing the phone after every uninstall. Repeat the same cycle until the issue gone.

Connect to other wifi networks

One good way to know if it’s a phone or router issue is by connecting your device to another known working wifi network. If wifi functionality works fine when it’s connected to a second network, then your problem lies with the router or how it’s setup. In this case, you should let your internet service provider or the company that provides the router know so they can help you figure it out.

Problem 3: Galaxy Note 5 can’t connect to wifi that requires portal sign in

I have a AT&T Samsung Galaxy Note 5. It is the best device I’ve ever owned! However, recently it has had wifi connection issues, namely when connecting to wifi that has a separate sign in page. This never used to happen. Say I open my wifi and connect to Starbucks wifi, then click on the sign in notification – or opens chrome then goes white for three minutes then reads “blocked due to https”? I think. It operates just fine with wifi that does not require a separate sign in page. Please help! I miss my device! — Jason Lantis

Solution: Hi Jason. Are you positive that the error message starts with “blocked due to https?” We can’t seem to find any error associated with Google Chrome that includes the wording you provide. Next time, when contacting any technical support team, be sure to provide accurate information to avoid confusion.

The only error that we are familiar of when Chrome is involved in opening a wifi portal is this: “Your connection is not private” or “NET::ERR_CERT_AUTHORITY_INVALID” or “ERR_CERT_COMMON_NAME_INVALID” or “NET::ERR_CERT_WEAK_SIGNATURE_ALGORITHM” or “SSL certificate error”

If that’s what you’re getting, here’s what you need to do:

Sign in to the portal

Wi-Fi networks at places like cafes or airports need you to sign in. To see the sign-in page, visit a page that uses http://.

  1. Go to any website starting with http://, like
  2. On the sign-in page that opens, sign in to use the Internet.

Update Android

We’ve noticed this problem to occur in devices running outdated Android operating systems. For a Note 5, it must be running Android Marshmallow in the least. To check for updates, follow these steps:

  1. Open Settings app.
  2. Tap Software updates.
  3. Tap Download update manually.
  4. The device will automatically check for an update, if one is available, tap Install to update.

Disable your antivirus temporarily

Some antivirus apps for Android provide HTTPS protection or HTTPS scanning. While such feature is a good way to block malicious sites, it can also cause the problem you’re having. In order to allow Chrome to log you in, simply turn off the antivirus app temporarily. Be sure to turn it back on once you’ve signed in to the wifi portal.

Ask staff from the establishment

If you’ve already tried the solutions above and the problem continues, be sure to let person in charge of said wifi network so they can look into it. Their network may have some special configurations that filters devices more strictly.
