On my previous devices, OG Droid, Incredible, I had to press and hold a button while powering up to boot into recovery. On my Thunderbolt, every time I power on my phone it boots directly into recovery, even if I only press the power button and no others. Today I had my first random reboot and it booted into recovery and the screen was on for at least an hour in my pocket.
Is this recovery boot process by design, or did I do something wrong? If I did something wrong, any ideas on what I can do to fix it?
