Chinese electronics giant TCL will not release any more BlackBerry-branded phones, the company has announced.
In 2016, it signed a deal to produce BlackBerry-branded Android phones, after BlackBerry decided to stop making its own devices.
It released several contemporary Android phones featuring the classic BlackBerry keyboard.
However, in a statement it confirmed that the arrangement would come to an end in August 2020.
In 2016, BlackBerry decided to stop designing its own smartphones in-house after 14 years.
Once a market leader, the company struggled to keep pace with rival handsets produced by competitors such as Apple and Samsung.
It attempted to launch a new operating system called BlackBerry 10, but it failed to attract popular apps to its platform.
The company now focuses on software and cyber-security.
Under the agreement, TCL could release BlackBerry-branded handsets featuring the iconic keyboard, which BlackBerry has several patents for.
BlackBerry Limited provided apps and a security-enhanced version of the Android operating system for the devices, while TCL paid BlackBerry a royalty for each one sold.
Announcing the end of the agreement, TCL said it had been “blessed” to work with BlackBerry on the smartphones.
