Some users are seeing Android is starting: "Optimizing app 1 of 1" or "Optimizing app X of X" continually for 10-15 minutes after a power cycle.
Please be advised the pre-loaded AllTrails application is causing the behavior. Please disable the application while a permanent solution is investigated
Settings > Apps > AllTrails
Select Disable App for removing user data for the application
Choose OK to replace the app with factory version
