The past few days I had some issues with storage space, so I moved a lot of apps to my SD card. Now today at 4:45 a.m. when I turned on the phone, it started "Optimizing apps" and can't get past that "Android is starting" screen. It's been on "app 4 of 54 (SD card)" for almost 5 hours. Nothing else will work, and I can't power the phone off. Help!!
