Right, it arrived today (Honor 7) and mighty impressed am I. It's still bigger than I would like but there doesn't seem to be a dual sim on the market of a sensible size with enough power.
Spent an hour or so setting it all up and it's way ahead of the ZTE which feels like a toy in comparison. Build quality seems excellent. The screen is lovely, the camera is very good and best of all, it seems to haul in a signal where no other phone I have tried (aside from an old Nokia) will.
Fingerprint sensor is super quick and I like the smart button. I've got it on 1 tap for calculator (I'm a calculating swine), two taps for torch and hold for camera. Torch works without unlocking which is cool. For camera all I need to do is touch the fingerprint sensor and hold in the smart button and I'm ready to shoot in less than a second. I think the sensor has swipe functions as well but not looked much at that yet.
It's really easy to set up which sim does what. At the moment I still have it set to VOD for 2G only, 3 sim on 3/4G. But you can swap in software in a couple clicks.
I'm actually seriously impressed with this piece of kit. I wish it was a little smaller, slimmer, lighter but other than that it's going to cost me next to nothing as a light user to have the current best network for 2G calls (here ate least) and also a decent data network as well and 321 is seriously cheap.
Thanks for the recommendation CheshireB, feel like I've got a proper phone again.
