It's good news, but there are problems:
- Lack of source code (certainly no link)
- Play Store (unknown source and functionality, vendor delivers product as a binary only)
So the claim that the App will work with any Android phone isn't true: there is a requirement that the handset has Play Store software (and, as is often the case with Android apps, may well depend on software libraries in the Play Store app or from Google Play Services). I'm surprised that the developers aren't aware that this is an issue, particularly as they were using a modern Nexus device to test the app.
So, my questions for Satoshi Labs:
- Does the app have source code available?
- Does it depend on Play Store libraries?
- Can it be distributed as an .apk through more reliable channels?
Source code is available on GitHub:

It wasnt having to do with earlier models. My trezor seemed to slow down significantly after the firmware update that came right after the discovery of that attack vector. But now it's seems to be back to the way it used to be. Also I could have just been experiencing an unlucky series of server problems with mytrezor.com around that time. Not sure.
I've found that using MyTrezor with a Trezor can sometimes slow things to a complete crawl, so I don't think it's any fault of the device itself. Whenever I've had issues with my Trezor being slow with MyTrezor, I switched to using Electrum with the Trezor and it was responsive again, so I suspect that most of these slow Trezor issues lie within the MyTrezor web app.
There were some issues with the backend server, which were fixed. If there are some issues, you can switch the backend server in the Settings in the myTrezor.com webwallet.
