Startled this AM when I pushed the power button to see read only memory, chip, bios, and OS data on a screen instead of the normal start up sequence. Instructions on the screen said use the volume level switch to move between commands. Options included reboot, fastboot, and power down.
I chose the power down option which turned off the phone briefly and then it turned itself on again this time normally,. The phone is making calls, getting email, etc. s appears to be working ok.
Is this a "feature" of an overnight update or anything I should care about?
