I am in the same situation and have been complaining about this since I bought my S8. Here is my latest post:
In summary:
- There is no info on the e-solutions web site saying that they sell phones with Oreo, which is really outdated and misses some key security features. All information on their web site leads you to believe that you will be getting a phone with Q installed.
- There is an unstable (i.e., develop) build for Android Q, but not Pie, and R. However, there are no step-by-step instructions on how to update from Oreo to the developer build of Q on the esolution phones. A step-by-step guide is needed that a non-tech savy person could easily follow.
- Based on the responses I’ve gotten on this forum, it appears to be more of a priority to push out new updates of the eOS ROM (which always seem identical to the previous version) and new versions of their iOS-clone launcher than it is to update the esolution phones from Android 7 and 8 to something more modern.
As you can see, I am frustrated. I REALLY want to be able to promote eos to my friends and family who are less tech savy than me. However, given their deceptive selling of phones with Oreo, and the unwillingness to put resources into updating these phones, I can’t. Maybe they will get this right at some point, hopefully before /e/ changes their name. At this point, however, you are stuck with a new phone running Android 8, and that is unlikely to change before you buy your next phone.
