To those that already have this phone.
How well does the GPS function on this device? Does it find your location quickly and does Google Maps do a good job of getting you from A to B with accuracy?
Just been testing this myself Will, I found that it took close on 15 mins to get an inital fix!! Not what I would call speedy for a cold boot.
Using it in a car, it needs a good view of the sky but in a built up area (high rises) it won't perform very well I'm afraid.
Having said that, as long as it has satellites and a good 3G connection, google maps works very well.
Secondly, the camera. Does it do a good job of taking 5MP photos? Daylight/Low light conditions, etc..
Haven't tested this much but in low light the pics are very grainy.
Lastly, with the Dual Sim. When you have a dedicated 3G data SIM in one of the slots, do you find that calls are missed/dropped with your primary "Voice" SIM? The reason I ask is, I suspect the SIM's share an aerial within the device and when the one SIM is working (i.e. sending Data or on a Call, not idle), the other SIM goes off network.
So far no problems. I have another cheaper dual sim chinese phone with a similar chipset MT6575, and this one was great. Only problem with it was the phone was very slow and had no 3G, only EDGE, but no problems like you mentioned. Hopefully this one will be the same.
