Frustrating. Other options: 1) Drop phone into lake, 2) Feed phone to on Ostrich (they'll eat anthing, as it turns out) 3) Bake at 450 degrees for 30 minutes, turning once to insure even results, 4) Launch phone off top of a tall building via slingshot, 5) Using Skill saw, remove top 1/2 inch of phone, 6) Secure phone to rear bumper of car with a string, place phone on ground, drive to work. All of these worked for me, and they solved my Ingress addiciton and texting while driving issues, too.
Seriously, hard boot worked for me, thanks for the tip!!
