How do i get my Nest to work on my new phone

[pnutalapati]

I got a new phone, my Nest app is migrated. When I try to open the Nest app, it asked to scan the QR code from the back of the thermostat(3rd gen), which I did, but it is asking for a number from the display of my thermostat(Settings --> Nest App), but I could not find that number. Thus the Nest app doesn't connect to my thermostats. The actual device says it's already connected to an account.  How do I get Nest to work on my new phone?

If you already set it up with your old phone, you don't need to do that setup process again. Simply sign into the Nest app with the same account you used on your old phone.

@David_K Thanks for your quick reply. 
Yes, I logged in with the same (email) account. In fact it has been automatically been done by the 'smart switch' app by the Samsung itself. On the home screen, when I open the Nest app, I could only see "Home" with address being mentioned, but no thermostat(3rd gen learning type) being shown as an icon, except a simple "+" sign. When I click on the '+' sign, then the 'add product' page opens with scan QR code window and a tip that it can be found at the back of the thermostat front display. I promptly pulled the thermostat and scanned the QR code, which was read successfully. Then next screen asks me to enter a key from the thermostat display supposedly from Settings-->Nest App -->key. But when I navigate to that place, I see a message that the device is connected to an app already. BTW, I could control my thermostat using my old phone still.
There is a 'delete thermostat' in the settings of the Nest app on my old phone. Do I need to remove the thermostat from the old phone first ? And then try some thing on the new phone ?

Please advise.

You can definitely do that. Let's try this:

1. Sign in to the Nest app on your old phone.
2. On the app home screen, tap Settings cog.
3. Tap your thermostat.
4. Scroll down and select Remove thermostat.
5. You'll then be asked to confirm your choice.

Once removed, retry setup in the Nest app on your new phone.
