Limited functions, inaccurate data, and lack of a cellular connection are among their complaints.

The findings are an indicator to makers of smartwatches and other wearables of what they need to focus on in coming generations of devices, Ericsson said.

Consumer objections to wearables are very legitimate, I can say, said Jasmeet Sethi, senior researcher at Ericsson ConsumerLab and author of the wearable report on the survey.

They see a lack of functionality, lack of connectivity, inaccurate data and a walled garden approach by vendors, but all four need to come together to ensure that wearables are a success.

While some wearable apps work across both the Android and Apple Watch platforms, Sethi said vendors need to work harder to create cross-platform functionality.
