How to switch between personal page and Brand Page in the G+ Android app? In Google Plus, I am able switch between my personal page and Brand Pages. (As described here.)

How do I do the same using the Android app version of G+?
The process has changed as of version 4.1. You no longer have to sign out and sign back in.

To switch:


Open the menu by swiping right or tapping the icon in the upper left
Tap the down arrow next to your name (or your Page's name)
If necessary, tap "Switch Google+ page"
Tap the name of the Page you want to switch to


The process is the same to go back to your regular account.



This is how to do it with versions 3.2 (or the version updated 11th October depending on your device) to 4.0.x. 

To switch:


Sign out
Choose your user account (if you have more than one)

If you've recently updated the app you may need to go through a few settings screens

Choose to sign in as yourself or one of your pages
