Annoying notification pop up

[Zaptor]

Update: this exact error pop up diseapeared after I switched from Chatr to Public Mobile. I still don't know if it was due to a specific app or just a weak Chatr coverage where I live.

I've been getting this notification pop up randomly on my phone.  I can't tap it or tap and hold to see where it's coming from.  I need to figure out if it's coming from an app or from Android.

I thought it's related to my carrier or my WiFi, so I reset my network settings, but still getting it. 

The message says "unable to connect to a network. Please try again. " 

Any help appreciated.

To see if it's because of a 3rd party app, boot into recovery & see if you still get it.

Is it happening on both WiFi & Cell Data?

If you don't already have it installed, Samsung's Noti Star (A Good Lock Module) may also help you to determine what is generating it.

Thanks. I'll try your suggestions. Yes, it happens on cell and wifi, and not just home wifi. I think it started when I switched to Chatr, but I'm not completely sure.

I installed Noti Star and it did not capture this notification when it came up. I then tried safe mode and I did not get this notif. I then wiped cache from recovery and haven't had the pop up since. I tried opening and using all my frequent apps and so far so good. I'll wait and see if it happens again. Thanks for the suggestions.

I experienced this once. I was trying to upload a large file using send large file service from Samsung. But the process seems to be stuck and got exactly same error message. I tried couple workaround still not able to fix it. I ended up factory reset my phone and problem resolved.

But you can try network reset and see if it can resolve your problem.

This seems to be associated with the Facebook app, so I tried turning that off and turned off all of my Facebook settings, and it still appeared. Also, I tried turning off Google Play services on my mobile phone, but that didn't seem to fix it. I also tried to update to the latest versions of the Google Play services, Android system, and FB app, and still no change.

Hi, As suggested by Tallman, we request you to backup and reset the device and check if the issue still persists.

Backup from Samsung account--Apps > Settings > Cloud > Backup > Select the data > Back up now. Backup from Google account--Apps > Settings > Backup and reset.

Here are the steps for factory reset, settings>>General management>>Reset>>Factory data reset>>Scroll down to the bottom and tap on Reset>> Delete All.
