Sony has issued an apology and software update after a barrage of complaints about its new handheld console.
The PlayStation Vita went on sale in Japan at the weekend ( it's not yet on sale in the UK or US). Users have described unresponsive touchscreens, crashes and freezes.
Glitches in new consoles are not unusual, but experts have been surprised by the number of related postings sent to Twitter and YouTube.
Local reports suggest over 300,000 devices were sold over two days.
The console boasts a gyroscope, accelerometer and electronic compass beneath its 5in (12.7cm) OLED touchscreen as well as front and rear mounted cameras.
However, complaints of technical issues have threatened to take the shine off the launch, prompting the company to issue a statement on its PlayStation site.
"Currently, our information centre regarding PlayStation Vita as well as our usual customer service centre are receiving many enquiries. We apologies if your phone isn't connected straight away," it said.
"Some issues regarding PlayStation Vita can be addressed by simple procedures at home," it added, going on to provide a list of questions and answers to tackle problems including the console refusing to start-up.
In addition the firm has released a firmware update that users must install if they wish to be able to continue going online with the device.
Experts said that other manufacturers had bounced back after facing similar early setbacks.
"One of the biggest problems Microsoft faced with its early Xbox 360 consoles were 'Red Ring of Death' failures - but the company overcame them and the system is now one of the best-selling in the world," said Christopher Dring from MCV, a video games industry magazine.
