Sony has acknowledged that it’s received a number of reports about technical problems with the PlayStation Vita, a  handheld gaming device that launched in Japan over the weekend.

The company said on its Japanese web site that Sony has gotten more inquiries than usual and it apologizes to customers for any inconvenience. The problems include the device randomly turning off, freezing or lagging during game play, and problems registering a PlayStation Network account.

Many new gaming systems have these types problems, but the statement from Sony suggests that they may be widespread for the Vita.

Cheap Ass Gamer founder David “CheapyD” Abrams uploaded a video explaining how he had to set up a temporary PlayStation Network account to download an update to fix a glitch that stopped him from using a pre-existing PSN account.

Sony sold about 321,000 units in its first two days of sales. But the positive reaction could very well be hurt by reports of technical problems.
