What to do if Galaxy S9 Plus is not making Calendar notifications when using Messages app

Hello Android users! This troubleshooting guide will answer three other common issues that a lot of #GalaxyS9 users are experiencing. Be sure spare some time browsing through the cases mentioned here to know if any one of them occurs on your device too.

Before we proceed, we want to remind you that if you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page. When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.

Problem #1: Galaxy S9 keeps getting “wifi network may not be available” error when connecting to third party devices like Amazon Alexa or wireless doorbell

I have a Galaxy S9 plus. I can connect to wifi networks with usually no problems. When I try to connect objects to our wifi, like Ring doorbell, myq garage door, amazon alexa, etc. I have to use my husband S7 to connect them. When you go through all their prompts and then it tells you to go into your wifi network and click on their network it should connect right off but it doesn’t. It just says wifi network may not be available. I know it’s something simple like a setting but I can’t find which apparently. Thanks for any ideas or help! — Trisha.bradley.tb

Solution: Hi Trisha. Yes, this may very well be as simple as setting up everything but you should know where to start. You’re saying you have a Galaxy S9 Plus but then mention that it’s your husband’s phone that set all the devices up so there’s already a disconnect there. What exactly is the problem? Are you having trouble setting up other devices to your wifi using your husband’s S7 or your Galaxy S9 Plus? Are you sure that your router supports all these devices you’re trying to connect wirelessly? We would like to help but we can’t get your point. Kindly get back to us with full details about the problem including the errors that you get when you set each and every problematic device. Unless you do this, there’s hardly anything that we can do to help in a concrete manner. We will update this post as soon as we have your response.

If you can’t get back to us nor provide details, we suggest that you contact your Internet Service Provider (if you got your router from them) and see if they can help you configure your router settings. If you’ll get errors on your phone while setting up a third party device on your wifi like Amazon Alexa, you can contact the manufacturer for technical support. Your problem does not necessarily mean that you have a Galaxy phone issue. Remember, you’re using third party devices in a wifi network and each and every devices in that setup can be the cause of the trouble.

Problem #2: What to do if your friend’s Galaxy S9 received SMS from your own bank

Somehow my Samsung S9+ has become connected to my friend’s Samsung S9. We haven’t intentionally tried to connect them, but my S9 Plus device shows as connected on his phone, and this morning he received a text message from my bank intended for me (which did not appear on my phone). He has previously been paranoid about people spying on his phone, and this event has made him very upset and paranoid of me. I have no idea how this might have happened – please give me some suggestions that I can implement (or show him) to prove that that could have accidentally been connected! — Harrietw

Solution: Hi Harrietw. We don’t think we understand the exact situation you’re trying to describe here and we can only guess what you mean by “connected.”  Pardon us if we interpret your issue differently.

If your friend’s Galaxy S9 now receives confidential text messages meant for you, it’s possible that this is not a coincidence at all. If both of you are using the same carrier, there may be problem on the network side that messed up your two accounts. We can’t give any specific network glitch how this is possible but it’s a possibility but you can check with your carrier about it.

SMS from banks are usually not sent at random and banks ensure that their official messages are only sent to the right recipient. Is it possible that you may have provided your friend’s number instead of your own when signing up for your bank’s online service? We suggest that check your online banking account details and see if this is the cause. Alternatively, you can ask your bank’s assistance in person and verify why their system sent messages to another number. If necessary, let them change the number on their system so you can be sure that they’ll be sending text messages to your number.

Unless you tried to use your friend’s phone before, there’s really no logical reason why he or she would be paranoid of you. If you did that though, kindly tell your friend that it can take huge government funding and highly specialized tools  to access and monitor a particular mobile device. Average Android users can’t hack his or her phone and spy on it. You can ask him or her to do a factory reset and be mindful of these few things:

  • do not visit suspicious websites
  • never click on an unverified link in websites or email
  • install apps from trusted developers only

Doing these three basic things should keep anyone from malicious websites, viruses, and phishing attempts.

Problem #3: What to do if Galaxy S9 Plus is not making Calendar notifications when using Messages app

When I am in the messaging app, I do not receive notifications from any other apps, such as Calendar app. This is a bad problem. Today I missed a doctor appointment because I did not receive a notification from my calendar while in messaging app. Also while I’m texting, I do not receive notifications for other text messages received.  I have checked that notifications are turned on, in the Messaging application and in the settings/notifications. I do turn off apps running in the background a couple times per day, but that should not turn off the notifications. — Gail

Solution: Hi Gail. If you’re using Samsung’s Messages app, it won’t notify you of any incoming text messages as long as you are actively using it. That’s normal and that’s how the app is supposed to behave in that situation. For other notifications though, that’s a totally different story altogether. Because Calendar is a separate app, you should receive regular notifications even you’re using Messages app unless you turned off Calendar notifications ahead of time. This situation may be caused by an app or software bug. To fix it, kindly do our suggestions below:

Clear app cache

Apps use a set of temporary files and other stuff to work efficiently. Sometimes, an app cache may get outdated or corrupted causing app behavior issues. To ensure that app’s you’re having issues with right now have good caches, you must clear their current ones first. Here’s how to do that:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap on More settings at the upper right (three-dot icon).
  4. Select Show system apps.
  5. Find and tap your app.
  6. Tap Storage.
  7. Tap Clear Cache button.
  8. Restart your S9 and check for the problem.

Make sure that you wipe the cache of both Calendar and Messages app.

Clear app data

Should wiping the cache of both apps won’t work, the next step would be to clear their data. This procedure will return an app to its factory state so be sure to back your text messages ahead of time. For your Calendar app, be sure to sync it to your online account so any unsaved appointments or events that were not previously synced will be stored online. Once you’ve backed everything up, follow the steps below to clear the data of each app:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap on More settings at the upper right (three-dot icon).
  4. Select Show system apps.
  5. Find and tap your app.
  6. Tap Storage.
  7. Tap Clear Data button.
  8. Restart your S9 and check for the problem.

Install system and app updates

Whether you have problems or not, it is always a good idea not to skip Android and app updates. Updates not only bring cosmetic changes and under-the-hood improvements but sometimes, also fixes for known bugs. To see if missing notifications from your Calendar app is due to lack of updates, make sure to manually check Settings for Android updates and Google Play Store app for app updates. If you get apps from other sources (not from Play Store), it’s your duty to ensure that they are compatible with the Android operating system version running on your device.

Reset app preferences

Should nothing change after doing all the suggestions above, you should consider resetting all app settings back to their defaults. Some apps need other apps or services in order to work properly. Sometimes, third party apps may disable a service or app intentionally or by mistake. To ensure that all necessary core default apps, follow these steps to reset all app preferences:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap on More settings at the upper right (three-dot icon).
  4. Select Reset app preferences.
