How do I check if my phone's running the Preview for Developers 8.1, or the proper update?

[Windows Central Question]

I have a Lumia 920, and I had subscribed and have been since using the 8.1 preview for developers. However, after I recently did a complete reset (factory reset) of the phone, it has since not been showing the preview for developers application. It's available for download, but not installed by default. I am not sure whether the factory reset pulled my phone to the official update or what.
Any way I can find the out?

unless you reset the phone using your computer you are still on the dev preview. However to still get dev preview updates you will need to install preview for developers and enroll again

Hope factory reset will kick you out of preview for developer... You may have the latest preview build but next time you will get update based on the official release..if you have installed PFD and enrolled again then you will get preview up updates....
