Your data is YOUR data!
An iPhone or an Android smartphone collects several megabytes of your personal data every day to Google Servers, even when it is inactive.
Murena smartphones have been designed to offer a different approach to users who care about privacy and data-hungry handsets.
Those smartphones are running the open-source “/e/OS” operating system, which is fully “deGoogled”: by default it doesn’t send any data to Google and it’s been designed to offer a great and natural user experience.
/e/OS is paired with carefully selected applications. They form a privacy-enabled internal system for your Murena smartphone. And it’s not just claims: open-source means auditable privacy.

It looks like these are Android phones that have just been rooted and had a different os installed.
As someone that happens to using e/os on a phone with an unofficial device. You are technically correct. They offer custom Roms for a variety of devices that you can install however they also have their own range of devices which admittedly is lack luster in terms of price to performance. From what I gather those devices try to follow in the footsteps of the Fairphone but with all the growing pains of a startup... I like the os. they offer cloud services as an addon that you can pay for which is based on nextcloud. The integration with the cloud services in surprisingly deep. Coming back to the fact that its based on nextcloud you also have the option to self host (which I recommend) and still benefit from the tight integration and that aspect alone is a major reason why I'm still using it. Gallery, notes,backups,cloud storage. All the Google like service's built in but without the Google
The biggest problem I've had with e/OS is the lack of apps. Banking apps, official apps, etc. All require Google Play most of the time. As an Android developer, I know how to make this work, but the average user won't.
I haven't tried in two years. Maybe things have changed.
I can't personally speak on the banking side. e/os has micro g implemented now, and on my device it passes the safety checks associated with it. To be fair though I can't give a full endorsement for how well micro g works as a whole (I'm not logged in) In general I've shifted to FOSS apps so my sample size for google play services reliant apps is limited but the one's I have used, open fine without annoying pop up errors.
