Ads on Lock Screen and Forceful Updates
I have an AT&T branded Galaxy S6 and since a few OTA updates back I've been getting ads on my lock screen. Sometimes the touch screen goes unresponsive. Meaning I press the power button to show the screen and it doesn't respond to touch but it doesn't appear to be frozen because I can toggle the screen on and off. Restart the phone and it works again.
I've tried the method of pressing the recent apps button to see the title given to the tile with the ad. No such luck. the title is empty which leads me to believe they're coming from the OS.
I've tried stopping the updates but I've found no setting to disable them. When I decline the updates are later forced on the phone seemingly regardless of what it's currently doing.
I've tried flashing the phone back to a previous state of the OS(Still version 7.0) but the ads live on. This made the touch screen unresponsiveness get better though. I suppose this will only last until OTA updates strike again.
My next step will be uninstalling all the apps that I can with the privileges I have.
Please post if you're having the same issue and if you have a solution. I don't know to do here so I've gone back my Galaxy S4.
I feel these problems might stop if I could revert to an older version and have a little more control of the device.
Anyone know where I can find version 5.0 - 6.0 of Android for the ATT Galaxy S6? Or if AT&T would provide something like this? Maybe Samsung would?
