tried to switch phone to new user; changed out sim cards; inadvertently tapped on upgrade prompt and phone has been stuck on upgrading for two hours; now on app 2 of 138; how do I make it stop?

Re: android is upgrading and stuck on app 2

Welcome to Android Central! Which phone? Did you do a factory reset? What upgrade prompt are you referring to? Was there a system update available?

If things are stuck, you can force a power down by pressing and holding Power for about 10-15 seconds. Then wait about 10 seconds, and power back on again.
