    I've had three times now an odd problem with my AT&T S21 Ultra. In each case I did a reboot with Vol down+ side key.

    I took a photo of the most recent event. It looks like an attack. In all three cases, I had just walked into a fairly populated area. I wonder if this is something sent via NFC?

    The screen shot is at this location:

    Hi, welcome to AC!

    Your screenshot you know thats download mode to flash firmwares, nothing there indicates a attack.

    Welcome to Android Central! You're saying that you see that screen all of a sudden, and then you reboot using the Vol Down and Side Key? Or do you see that screen after rebooting using those buttons?

    Download Mode is activated by pressing Power and Vol Down together when booting the phone: https://www.hardreset.info/devices/s...download-mode/
