Have a stock razr maxx. It's not rooted. Have not messed around with it much just standard apps. Powered off my phone and plugged in the stock wall charger. Woke up this morning, got up unplugged my phone. Looked down and saw a weird screen, plain black background with white lettering. Unplugging my phone was the first thing I did upon waking up, so I wasn't exactly thinking clearly. Instead of writing down or taking a photo of the weird screen. It said press the power button to return to normal use and that's what I did. i remember it referenced plugging into a USB and the title at the top of the screen was "flash" something... The razr was at 40% charge when I turned it on. This may be explained by me not fully plugging in the micro usb or the outlet plug. I know not a lot to go on but since I'm late to the party hope this has happened to someone else.
