(I received notice June 10th, and updated June 11th.) This latest software update (n960usqu8fue1) for my Galaxy Note9 told me I had changed my SIM card (not true) and needed to restart my phone to access my "new service provider." I was forced to do a restart. I couldn't exit out of the screen. I tried powering off and removing and replacing my SIM card. The screen remained in place until I did a restart. A few AT&T apps then appeared. I use Cricket and do not wish for anything to disrupt the unbeatable and no longer offered plan I have. I also received SEVERAL!!! unwanted game and news apps! I was able to delete these apps but could only "force stop" and/or disable the AT&T apps. I now also have a header in my settings menu that tells me "A software update is available." That's what got me into this mess in the first place. I have also checked for software updates to verify there are no further updates. I can press X to make this temporarily disappear, but it returns as I move around or in and out of the settings menu. It was my understanding that this unsolicited update was supposed to be a patch for fixing bugs. I didn't have any bugs until after the update. I looked before the update and had Android version Q. Now it tells me I have 10. I believe they are the same, being identified as Q in it's earliest release - except for the updated bug fixes I suppose. I'm really very unhappy with what just happened to my phone and hope a fix will come out soon. I also hope this is a glitch that doesn't actually mess with my service provider. In all fairness I do have a phone that was supposed to be completely unlocked that would bring up an attempt to activate OMADM whenever restarted, which I believe is a Sprint thing. I would deactivate this each time. In all the time I've owned this phone I've never had an update (been through quite a few) try to tell me that my SIM card or my service provider had changed, but I wonder if this could have had something to do with it? Still, it has never caused complications previously.
