That's sad, and so backwards...

If they really wanted to make sure the data on the phone is safe, the integrity checks should be about making sure the phone is built from FOSS with available source code, that can be publicly audited and even the banks themselves could check it for security.. which should actually rule Google services out, not the other way around!

Well, it's not a cheap phone, but it's a phone for the rest of your life, it's full modular, that means, you can fix and change everything by yourself any component of the phone, no need to pay money to an technic workshop. Apart it offers also sys specs which fits the price.
