This is my first smart phone so I can not compare it to any other, but I find it speedy and powerful. The battery is good until you turn on wifi or use camera/video play back then it eats it up. Music playback with poweramp app is superb, sounds even better than my ipod classic, so really impressed. I can navigate to what Im after quickly with the customisable home screen. I just watched Tin Tin in 3D on the phone and it looked really good. Autostereoscopic is definitely the future, never been a fan of wearing the 3D glasses.
My main issue is the camera. I have a 3DS and really enjoy 3D photos, I think they really add something to an image. The issue with the 3Ds is the resolution of the images was very very poor. Although the photos are now 5mp on the Evo3D which is enough, the quality of the photos is not so impressive. You may not notice so much on the phone screen but when viewed on a computer monitor it does not hold up. The camera does not not capture colour well, and all images are quite desaturated, and also suffer from colour bleeding issues (for example if I take a head and shoulder photo of a person in a park, there is a slight, but noticeable, green tint to the person). In conclusion the photos look good on the screen, in fact they look great in 3D but is disappointing when viewed at a larger scale, and I would not use this instead of bringing a digital camera to something of significance
