Fast CPUs (Snapdragon 400), sufficient fleet graphics, RAM is sufficient to 1GB.
The highlight is the GPS: I did not have a phone that without irgenwelche aGPS hacks, so rapidly is satellite and a fix supplies.
The battery lasts loosely over the day.
The display is bright enough and the colors come across very nice.
The camera produces pictures in daylight quite good, and in the evening with the night mode and a steady hand can still be reasonably shoot.
Negaitv is so far only that Bluetooth in the hands-free mode, ie with a speakerphone, even makes a few zicken what is hopefully solved with the next software update (with my Xperia T, which I still have and I'll wait even a few months on an update that makes me use the phone in the car again).
A little tip: Since the phone is usually delivered with an English / Chinese ROM, you should stop by on the side of MIUI Grmany where there is a current, eingedeutschtes ROM. The installation is to be managed without any tricks and one also does not lose its warranty.
Whoever pays a little to the euro, really get a bunch Phone for his money, I had here at a dealer 160, -EUR paid incl. Accessories.
