The Chinese tech firm's operating system will be more widely used next year, but the brand's biggest devices won't be getting the software just yet, according to Wang Chenglu, the president of the Huawei consumer business group's software division.
Harmony was introduced back in August, and it was first used on a "smart screen" called Hongmeng in Chinese.
However, the company insisted they would still use Android for smartphones, but aim to get the software on their smartwatches, speakers and virtual reality products.
Huawei's CEO of Technologies, Richard Yu, previously insisted their new operating system isn't to replace Android.
Despite reports that the company created the system to be less reliant on Google's, the tech boss said they were still planning to work with Android.
He said: "The phones which are currently on sale can continue to use Google.
"That's why we have HarmonyOS for backup, in case we can't use Google in the future.
"Then you can use HarmonyOS, which will have better performance."
Yu also stated that they are hoping HarmonyOS can be used on smartphones.
He said: "It will be minor, minor work to transfer apps from the other ecosystems to HarmonyOS: transferring this ecosystem will be very easy to do."
Though this isn't in their plans as of yet.
Huawei was added to a list of companies that US firms cannot trade with unless they have a license, amid the fears of national security concerns, but Yu vowed: We are heading for the best products, the best innovations, the best user experience.
"That's what we are looking for and you can see that if this trade war had not happened then this year we had a very big possibility to be number one.
"So, this year maybe our market share cannot be number one but we consolidate the top two position. For us the market share is not the most important. The innovation, the user experience, customer satisfaction are the most important."
