I prefer Sony smartphones over Samsung because of its good build quality and attractive slick looks. The problem with Sony phones is there poor software support means just for example there ICS upgrade program is horrible the ICS Roms are still quite buggy and there 2011 xperias ICS upgrade is not usable by any mean for daily normal use like broken Wi-Fi, Tethering problems, lagy GUI, restarting, camera video lag and the list goes on..... But if we are not bothered about upgrading OS of the phone and can enjoy the smooth fluid stock ROM then Sony is the best choice .
