EU Settlement Scheme Questions - smartphones + previous leaves

[dialectic]

My spouse (EU citizen) and myself (non-EU Spouse) are thinking about applying for the settlement scheme in its current beta phase.

Details:
My spouse has a PR document. I have a FM BRP. Marriage was in May last year. Living together and been doing so from before we married

Due to traveling I want to avoid having to send passports/residence cards. I understand these can be scanned with the app. However, my phone doesn't have NFC technology to scan these document chips. However I understand my spouse's idiot-phone 6 can scan these.

Is it possible to do the application both of us using the same smartphone (My spouse's)?

I used to be on Tier 2 and Tier 4 previously. Is that relevant to the application? Would my previous leaves affect it?

Thanks a lot for your help

The app currently only works on Android type phones - not IOS.

Oh, sorry. Didn't know that

I suppose a borrowed phone would be acceptable for the application?
