Android 15 Turns Off Wifi Automatically

[DaveZiffer]

My Samsung A54 updated its operating system to Android 15 a couple of weeks ago. My phone will now seemingly randomly turn off its WiFi when I'm away from my WiFi connections. For example in the past two days I had to visit a particular office. My phone was on and connected to my home WiFi when I left my house. Upon arrival at this office, I noticed that my phone's WiFi was turned off, despite the fact that I had not manually turned it off. Thus, if I had had an existing WiFi connection there, my phone would not have reconnected to it, since WiFi had been automatically disabled. Tonight I took a walk two blocks away from my house and pulled out my phone, and the WiFi had been automatically disabled. In the prior 20 months of using this phone (with the previous version of Android) I never once experienced this problem.

Check your intelligent wifi settings to make sure turn wifi on/automatically didnt get turned on. Settings/connections/wifi - tap the dot menu, select intelligent wifi and check the settings.

Wow am I glad you found my post here. I checked that option and sure enough it was turned on. Considering that I didn't know that that option even existed, I could not have possibly enabled it by myself. I will test this tomorrow and see if it solved my problem. This may also have solved another problem I noticed: I'm an Xfinity user, and formerly my phone connected automatically to public Xfinity WiFi hotspots; now it not only doesn't connect automatically, but it also requires a sign-in when I try to manually connect in places where I know such hotspots to exist (it never required authentication before). I will keep you posted, and if this reverts my phone back to its former operation, I will mark your post as the solution. THANKS SO MUCH!

Yup - you were right. I turned this off and it fixed the problem. To  your comments I would add that "Intelligent WiFi" is subordinate to "WiFi Scanning" (in the "Locations" settings), i.e. "Intelligent WiFi" can be turned on/off only if "WiFi Scanning" is enabled. Further, the Settings seem to be set up so that when you enable "WiFi Scanning", "Intelligent WiFi" gets enabled automatically. 😣  SO ... since I didn't want WiFi Scanning on either, I disabled "WiFi Scanning". Be warned that if you turn "WiFi Scanning" on, you will automatically enable "Intelligent WiFi" by default. THANKS FOR SAVING ME HOURS hopelessly trying to get answers from either Samsung or Xfinity. 😁

It's very bad that they even have that setting hidden rather than right out in the settings grouping.

It's very bad that they change everything (including stuff you don't know about) without telling you, and then expect you to figure it out for yourself. 🫩
