I just bought a Moto G6, and I like it much better than the G3 or G4.
It's a bit more narrow than the G4, but doesn't seem to suffer from the most reported issue of the G4, namely the "ghost taps" which are annoying enough that I'll be shipping my G4 back for service, while it's still under warranty.
Not sure how well you can see it, but here's the G6 (left) and G4 (right), side by side, for size comparison, with almost identical protective cases. In the 3rd image, the G6 is on top of the G4, and you can see some of the G4 sticking out. It's not a huge size difference, like it was going from the G3 to G4, but if you are hoping for an even bigger screen than older models, it's not going to happen. As I stated before, the screen is actually smaller. You might perceive this as either a good thing or bad thing, depending on the size of your hands or pockets, or other factors. (one of my favorite games is ad free on the G3 and G6, because of screen size, crediting me with bonuses for viewing video ads, without actually showing the ads. You get stuck with video ads on the G4's larger screen, because the game treats it same as a tablet.)Looking for smartphoneLooking for smartphoneLooking for smartphone
Battery life of the G6 doesn't seem as good as the G4, though, even though they are both 3000 mAh. And you'll need extra USB-C chargers, as all your existing micro-USB will be useless with it.
Sim & SD cards are inserted from the outside, into a little slide out tray on the top edge of the phone, rather than having to take the back off the phone to install them. And despite what is advertised, it does support SD cards over 128G (I have a 256G in mine). The cards seem to be located away from the battery, unlike previous models. Perhaps this will help ensure that the heat from battery, during charging, won't knock them out, which is something else I experienced frequently with the G4 and only occasionally with the G3.
It works well with thicker protective cases, and you'll probably want one of those rather than a thinner case, because the glass on the back that covers the camera sticks out far enough that if the case is too thin or you use it without a case, that glass will hit the table when you set the phone down.
I got the Amazon Prime version, so double clicking the power button activates Alexa, rather than turning the camera on. But like previous Moto G models, making a chopping motion still turns on the flash light, and twisting turns on the camera.
Would I recommend this phone? Absolutely! I still feel it's the best phone available in this price range, and affordable enough to get one, unlocked.
