The bottom buttons flash as if I'm holding down on the power button.
I am unsure if this correlates with my sim card errors either, but tis quite annoying.
I tried to press home button last time this happened, and got a screenshot reading:
"TO RESTART YOUR PHONE, CONTINUE TO PRESS AND HOLD THE POWER BUTTON FOR 2 SECONDS"
So I'm wondering if anyone with a otterbox case is experiencing this too.
I even went as far as to take the top of the case off, and the countdown timer paused at 1 for a few seconds and proceeded to restart anyway
