BlackBerry handsets need more applications to be successful, according to the company’s CEO John Chen.

In an interview with technology site Re/code, Chen conceded the company’s recent BlackBerry 10 handset launch had not done as well as he had hoped, partly because of a lack of applications on the device.

“By any definition it is not a runaway success,” said Chen. “It’s not competitive to Google Play or the iTunes store. We’re working hard on that.”

Chen, who was speaking in California last week, also stopped short of confirming that BlackBerry’s next handset will run on the Android operating system.

Recent leaked images of the upcoming “BlackBerry Venice Slider” handset shows the device running with standard Google Android applications, suggesting the device will have a full suite of Google apps and services.

BlackBerry 10 phones can already run some content designed for Android by using the Amazon Android app store, which is now accessible on the devices, but access to these apps is fairly limited.

Re/code reports Chen confirmed BlackBerry’s continued commitment to remain in the handset business for the time being, but conceded the company could be forced out of the market in the future.

“If I can’t make money on the phone, I will be out of that telephone handset business,” he said. “There is a timeline; I won’t tell you when.”
