It is Android. Dumb title.
/e/OS
A community about the /e/ Operating System developed by e Foundation.
/e/OS is a degoogled version of Android. It aims to be a good balance between privacy and usability. Forked from Lineage OS.
In principle yes, but AOSP derivatives without e.g. Google Play are not allowed to be marketed as Android, see e.g. on Wikipedia:
While AOSP is free, the "Android" name and logo are trademarks of Google, which imposes standards to restrict the use of Android branding by "uncertified" devices outside their ecosystem.
Or in the FAQ of AOSP:
The function of the Android Compatibility Program is to define a baseline implementation of Android that is compatible with third-party apps written by developers. Devices that are Android compatible are eligible to participate in the Android ecosystem, including Google Play; devices that don't meet the compatibility requirements exist outside of that ecosystem.
In other words, the Android Compatibility Program is how we separate Android-compatible devices from devices that merely run derivatives of the source code. We welcome all uses of the Android source code, but to participate in the Android ecosystem, a device must be identified as Android-compatible by the program.
I'm on e/OS and it works pretty great. Except phone calls usually won't hear me unless the mic is enabled before the call rings.
Also it won't takeT-Mobileas MMS if cell signal is zero.
Sounds like it works like shit
That's an issue of the particular device, not of /e/OS itself.
First one yes, drivers could be better. The second one I'm blaming on T-Mobile.
Ater an update a few months ago, I've had Issues with my FP5 and T-Mobile (Germany) as well, but it was definitely the drivers, as it worked before. The chipset suddenly didn't like the frequencies used by T-Mobile for 5G and lost connection after a few seconds. Fortunately, it was fixed by the next update.
I have not had issues with t-mobile mms, even when i have no cell signal and am on WIFI calling.
What APN settings do you have?
T-Mobile US

Basically the same as the T-Mobile site except they have MMS protocol as WAP 2.0 and I don’t seem to have that setting.
Edit: changed the last statement as MMS protocol is not in my APN settings
