The Vita was released in Japan back on the 17th, shortly after, stories popped up on the internet saying that the first batch of Vitas have been suffering problems including power issues and the touchscreen not responding.
Sony however has said that it is to be expected that some of the 325,000 units would malfunction in some way, but that the problems reported are definitely not exceeding what these expectations are. The PSV had a fantastic launch and sold like ice cream on a hot day. However, David Wilson, head of Sony’s UK public relations has said that they can’t find evidence of the glitches.
He went on to say that stories about Sony issuing an apology about the Vita glitches were a falsehood, and that the only apology given out recently was one relating to people having trouble getting through the tech support helpline, and a standard page showing how to work the Vita.
Basically, things have been getting lost in translation which is perfectly possible in Japanese to English, the whole idea of the PSV being faulty is quite overblown. There is indeed proof of the frozen screen issue, but this is to the knowledge of most the only recorded issue of a problem, not exactly making the whole thing widespread.
Thankfully, if you do get a faulty Vita it’s not difficult to have it replaced for a new one under warranty.
