Unless you can fully replace the operating system with a custom firmware, it would be a very bad idea to repurpose an old phone for this.

You're right. The more I think about it, the more obvious it is that using Android hardware for Krux would require a lot of work in order to make it secure. I was just thinking out loud, since there are so many old phones just waiting to be repurposed rather than thrown out. Hell, I still own an iPhone 4 that I used to use as a bedside clock. But, yeah, it'd be a huge undertaking to make those kinds of devices truly secure for a hardware signer, whereas something like an Amigo works out of the box.

It took me less than 5 minutes to get Krux up and running on an Amigo, and I could do it again in less than 2 now that I know how.

That sounds great! Do you want to share any pictures of it?

I don't have any yet, but I found this on Twitter. That's Krux running on an Amigo. Note that the text in that pic is orange. That's one of the theme options for Krux. I prefer white, and there's also an option for black text on a white background.

Really, the Amigo seems like a perfect device for this. It's a chunky device, but it has a nice sized touchscreen and you'd only need it to sign transactions. Well, that and setup stuff, like creating a SeedQR.

Again, I have no experience with this thing yet, other than playing with it for an hour or so... so I'm trying to keep my enthusiasm in check in case there's some fatal flaw I haven't discovered yet... but I am truly blown away by this setup.

It's so simple.

I wish these guys had more support though. Krux has so much potential, so I wish more people were working on it. For example, I wish each page had an "i" icon to click for more info. A touchscreen is perfect for that, especially since there are some options in the tools and settings that could be intimidating for new users, such as "Delete Mnemonic" ("Wait, didn't it get wiped out when I shut down the device?"), and at the bottom of each page's info I'd love a "Reset setting to default" option for that setting.

I'm just getting started with testing Krux, but I can't overstate how enthusiastic I am about it. I've been wanting to get a SeedSigner for a while, but for my needs, this might be much better thanks to the larger screen and how they implemented the passphrase feature.
