And if it wasn't for these apps (for example banking apps, since someone decided that it's now impossible to use your homebanking from a PC since it's not secure enough) I would already use a Nokia 3310.
Only thing missing is contactless payment but there are European banks that support GrapheneOS without Google Pay so alternatives exist. And I can use Garmin pay with my watch (and offline and without Garmin Connect thanks to the FOSS GadgetBridge appp) if that was necessary.
The false claims of "It won't work" in HN comments keep getting more bizarre
It's unclear if this is a myth, a misunderstanding or a deliberate falsehood but it's oft repeated
Here the original comment did not even make any claims about mobile banking
But it still triggered a reply with a false assertion about mobile banking
Mobile banking usage differs from country to country
Not every country is the same with respect to mobile banking usage, not to mention mobile usage in general
As for people who would use GrapheneOS, a small segment of conscientious mobile users, I wonder how many have or could end up with multiple phones as a result of planned obsolescence and forced "upgrades"
In such cases they might have one phone that runs a corporate mobile OS and "approved" apps and another that runs a non-corporate OS that runs "unapproved" apps
There are many possibillities
