The Librem 5 is a Linux phone that the reviewer tried to use as their daily driver for a week. However, they found several issues that made it impractical for regular use including poor battery life, a subpar camera without basic features, and lack of compatibility with many popular apps. The reviewer also noted problems with the phone randomly powering off and convergence mode with the next dock being unstable. While the reviewer thought the Librem 5 was a cool device, they ultimately decided it was not ready to replace their main phone due to these limitations and instability issues. The reviewer expressed interest in reviewing other Linux phones if provided to them.
