He took over from my old HTC Desire which gave me a certain pleasure for almost 4 years since the undercoat HTC Sense was pretty well designed, unfortunately it ended in a fall ... and goodbye mobile . well, with this Birdy, I'm not disappointed, it is a bit big for me but is still reasonable; the processor turns fast enough, the mobile is very responsive (enough RAM), the screen is sharp, the colors are vibrant; and with the Android OS 4.4 kitkat, no surprise, the system is very intuitive and well designed, it replaces the HTC Sense. nothing to say, for a relatively low price compared to the same range of mobiles with the same specifications (4G)
