I actually had the opportunity to briefly hold this phone a while back. Although it looks like the old LG Cosmos, it is 4G and made custom (in China of course) for this seller. The main attraction of this phone would be the full qwerty keyboard (I miss the Brightside and Xpression) but it overall does not feel especially high quality, the slide feels a bit junky, and the overall plastic outside feels cheap. But I think there is some warranty it comes with, and they can fix it for cheap themselves. It isn't touchscreen, so it comes with a mouse to use with Waze.
From what I can tell the system seems to work for what it's meant to do, but I do not have experience using it, so I can't know for sure. There have been some reports of bugs, but they do send fixes with OTA updates. I haven't tested the call quality, but it does work with all carriers.
I don't remember much about it, I guess we'll have to wait for [Login to see the link] full review
Edit: I know I kind of just listed the negatives, so I may have made the phone sound worse than it is. There are also a lot of good parts, I just don't remember details, but I remember checking known issues with other phones that this didn't seem to have. The question is when it's worth the price tag
I also just remembered that it had the actual Gmail app (I did not try to use it) which is unusual for such phones, I don't know if it has Google play services or they got around it somehow.
