Good to know. I haven't played with Oreo. Waiting for the public release.
I jumped to that conclusion because he said that exchanges of the phone itself fixed the problem. If the firmware is the same, then the logical conclusion is that there is a hardware issue as opposed to a software one that can be fixed by flashing an update. No?
There are just so many variables it's hard to say without completely speculating. That's whats so frustrating about this issue because neither Sprint nor Essential seem to be fully upfront about the problem. I think that's because to the general public, they don't care about specifics, they just want a working device.
Theres a small subset of the community here and on Reddit that want specifics but everyone else just wants a phone that works.
Here was the official thread on Reddit explaining things if you're interested:
I think honestly it might not have anything to do with Oreo, it's probably just the sprint network updates they pushed out via the Play Store. I've had a couple in the last month or so. My bet is one of those resolved the issue for me.
