According to Roadmap March is PRIME I month.
https://developer.gulden.com/roadmap/MaNI when will we hear the details about PRIME I and good job on 1.6.0 update, love the new wallets and link feature from my Android. A question, do I only need to keep the passphrase for desktop wallet and I can recover my Android Account funds?
The desktop passphrase is all you need for all accounts on the new desktop wallets, the devs don't read this forum anymore so I highly recommend you and others join slack. These questions will be answered straight away.
