***** Edit ****** my method below does not work. I thought I was on to something, but it's a no go. Sorry if I led anyone down the wrong path. It seems like Samwathegreat might have the most viable solution thus far, I am just too apprehensive to try to root my phone at the moment. Would love to though.
***** End Edit ******
People who do not suffer from this problem, although we appreciate their caring and effort, they simply won't be able to help. It's up to those of us who have this problem to figure it out, as Comcast is clueless.
My current strategy on my Samsung S9 is this:
Settings>Apps>(three dots at the top right)>Show system apps>
Look for 2 different apps
1. Xfinity Wifi Connect (or something equivalent) - uninstall this POS.
2. Carrier Wifi - go in and disable this POS, doesn't seem like we can uninstall it.
The following I can confirm does NOT work, however it can't hurt in my opinion:
Settings>Connections>Wi-Fi>(three dots at the top right)>Advanced>Hotspot 2.0>Xfinity Mobile
Turn off "Auto reconnect"
Any standard Android user will tell you to just "disconnect" or "forget" the Xfinity wifi next time you are connected. This in theory works, except for two problems:
1. It only forgets the current MAC address of the Xfinity access point you are connected to, not all SSIDs labeled "xfinity" or similar
2. I have seen it happen on my own Xfinity-provisioned modem/router, the MAC address can change after a reboot/reset/or remote operation by Comcast technician, which gets us problem number 1 as above all over again.
Basically, Xfinity support is useless, but hey when you subscribe to the only provider in town, there isn't much choice unfortunately. I hope my steps above can help us crowd-fix this issue if we can just figure out what to disable.
I can say with 100% certainty that if these settings do somehow work, they will need to be performed each time Samsung issues an OS update. Everytime the OS gets updated (seems to be monthly recently), all of the Xfinity-related apps and settings return to their default from the carrier.
Best of luck everyone, I am glad someone started this thread and I am not the only one out there trying to browse the internet on the bus but not able to because I keep handshaking/disconnecting from random Xfinity hotspots out there. I appreciate that Xfinity offers them, I just do not want to be force-fed them.
