Sonic Defender
Headphoneus Supremus
In the exact same boat as you guys... Still love the G3, although I am feeling the itch to upgrade. Strongly considering the GS7 (mainly for the fact that it has a really nice amoled screen and ip68 rated). But I'm unsure of whether or not the E18 will work with it. If it doesn't work with it, it's a total deal breaker for me.
But in all honesty, phones have really started to bore me over the last year or so, there's nothing new and exciting, nothing that makes me absolutely want to get a new phone. Sure, the new models are faster, but there are no new features (other than the ip ratings)... So I guess, for now, Long live the G3
Still loving the G3 as well, and I agree, sure more bells and whistles available with newer models, but the G3 is technically quite sound and runs Android 6 like a charm so I'm happy with it. I know in a year with the way new toys are eventually I'll want to try something new. I will say that if you use the headphone input while the sound quality is good it is not anywhere near powerful enough for my liking. Doesn't effect me as I use Bluetooth anyway.
