No wonder the retailers in my area bluntly tell me to avoid Sony Ericsson & also Motorola.
Its very true in my whole home state (Bihar)
SE phones seem to have a good build quality. Their failure rates are far less than competitors much like Nokia.
Well, I'm a bit of SE fanboy, still, SE's build quality is no where comparable to Nokia, at least. About failure rate, see this- when i had to buy a phone some 6 months ago, I found at least 10 persons in my whole "network" using SE,
ALL of them reported
BAD SERVICE, and hardware failure (especially displaying going kaput), no battery back up after prolong use, and hell lot of problems. My heart just wept

I have used lots of SE phones, so can say that only
K series where upto mark, one of the best, especially K750i.
