I'm trying to figure out how this Blockstream (npub1jg5…6n8n) Jade works to set a noob up with one.

It works ok with Sparrow and USB but my goal is to configure them a mobile wallet where they can DCA easily while still using a passphrase and without using a cable.

The firmware upgrade took way too long due to a glitchy cable that always failed to push the firmware past the 10% to 15% mark.

The Android phone is a bit old, so the camera is almost impossible to get to focus on the screen of the Jade and trying it with my phone I noticed that a major issue is that the text next to the animated QR is way brighter than the QR. Covering it with a finger or better something flat helps a lot. It'd also help a lot if the text to the left wasn't 10 times brighter than the QR code.

The BT connection is super glitchy, too. Their FAQ suggests to "forget" the device if needed several times to see if it starts working when pairing again.

I'd like to see an upstream bug report cause it sounds like a bug in their control that they should fix instead of writing such an FAQ entry. Or for what it's worth, a link to their own respective bug report. Jade is open source after all.

I tried out npub1cvqlzvmjercdn0ypsmv8f7j9lge6ahsnueh5rparh53wuswftv4q49yjt3 (npub1cvq…yjt3) for Android and there is no BT support but somehow I did register a key with it by scanning a QR code but I then could not figure out how that worked. On the freshly started Jade there is really not many options. Turns out I did unlock the device fighting with Sparrow and it was still in the unlocked state which allowed the QR export which is unintuitive when you haven't figured out yet that it might be unlocked or not and depending on that, behaves differently which led me to try to scan the only QR code I could get to: QR Mode -> QR PIN Unlock but Nunchuk behaves weird with that QR code: It counts up to 100% but then does nothing at all. It just keeps scanning. As Nunchuk explicitly supports the Jade, maybe it could do the same as https://jadefw.blockstream.com/pinqr/qrpin.html is doing to help a brother out? To my understanding at this point the "virtual" SE is queried for a KEK? Or if Nunchuk can not emulate that website, maybe it could tell the user what to do instead of just showing "100%" with a video stream.

So last questions for Blockstream (npub1jg5…6n8n): Why can I not see the balance without typing in pin and passphrase on my present Jade? Why does Green keep asking for permission to share some key for Liquid? I really don't want no wrapped Bitcoins so it should just stop asking.
