Signifying an end of an era and the complete dissolution of the BlackBerry app ecosystem, the BlackBerry app store will close its doors for good on December 31, 2019. This means no access to apps or updates of apps for BB10 devices which, at this point, are only being marginally supported. Even the BlackBerry PRIV is no longer supported (no more updates) which means it can expect to die a slow excruciating update-less death. This is BlackBerry the company washing its hands completely from their mobile devices, which at this point, are just a burden to support.
Now, BlackBerry Mobile, a subsidiary of TCL, is the company that's released the KEYOne and the Motion smartphones and they will continue to create and support those devices. They have nothing to do with the PRIV or earlier handsets but are offering a possible trade-in program to help users transition to newer devices. It's a sad reality but one that has been coming for years for true BlackBerry fans. Many of who have had to sideload Android apps just to try and get by.
