Its been few months Ive been using Experia Neo, its quite a good phone, Camera clarity is good, battery life is above average and very good to play games. Ive never experienced any hanging or software or hardware problem till now.
Only thing is the internal memory is less, if you are a gamer u will have to use apps like task killer to free internal memory. rest is awesome.
It looks great, touch experience is good, It comes with ginger bread version, I dont want to update to later versions as it might make the phone slow
Sound is the best feature of this phone.
