Norton Mobile Security is telling me that I have connected to an unsecured network, when I don't believe I have. This has happened to me before, and I have previously posted about it. See https://community.norton.com/en/forums/wi-fi-security-rating-mobil-norton-security-home-page
This time the circumstances are different and the "fix" I accepted no longer works. Therefore, I'm starting this new thread.
My phone and carrier has changed since the earlier thread. I am now using a Samsung Express Prime 2 phone on AT&T's network. It is running Android 7.0. My wife has an identical phone with the same carrier and OS level.
The recent problem first occurred on my wife's phone. Immediately after restarting from an Android security upgrade, a Norton Security popup was displayed stating "You're connected to an unsecure network ...". I opened the Mobil Security app and saw that it was displaying a "WiFi Security" score of 70%. When I click on "WiFi Security" it says "You've connected to unsecure WiFi networks ..." and shows my network which is, and has always been, secured. I immediately checked the phones WiFi settings, which showed, appropriately, that it was connected to my WiFi and displayed the lock symbol.
Of course, I hadn't checked the WiFi security score in my wife's phone immediately prior to the upgrade. However, my phone, which had not yet done the Android security upgrade, still showed a "WiFi Security" score of 100%. I then did the upgrade on my phone and the exact same thing happened - I got the same popup on restart, my "WiFi Security" score went to 70%, and my WiFi network was shown as the unsecured network.
My best guess is that in the upgrade/restart process there is some delay in the availability of the WiFi connection status which caused this to occur. It may be more of an Android problem than a Norton problem, but in the end it's a false positive.
There is also a problem with the "fix" I accepted in the previous thread. In Android 7.0 it is no longer possible (I believe) to erase the NMS app data as a way to reset the "WiFi Security" score. If there is any way to reset the WiFi security score, short of uninstalling and reinstalling the app, I would be interested in hearing about it.
I don't mind very much that the app isn't perfect and can generate an occasional false positive. But there should be an easy way to clear such detections, and users should not be nagged to sign up for Norton's VPN service.
