Jolla’s official website announced the release of Sailfish OS version 4.5 (codename Struven Ketju), the flagfish operating system.
Sailfish OS 4.5 Struven Ketju features several improvements, especially in Android App support, addressing many of the issues raised by the community over the years, such as connectivity improvements, Bluetooth scanning improvements and audio control support, keyboard layout improvements, account login process improvements, better Android notification integration and browser compatibility.
Android AppSupport for Sailfish OS has now been upgraded to Android 11 and also supports microG services, allowing users to run some apps without signing up for a Google account.
In addition, the Android 11 update brings a number of improvements to the Android AppSupport integration. From the Android side, new privacy features mean better separation between Android apps, scoped storage now also applies to external media, as well as support for one-time permissions, and stricter restrictions on background location access.
Sailfish OS 4.5 also features a number of audio optimizations to keep the experience consistent between Android apps and native apps, as well as the ability to control the volume level of individual Android apps.
Sailfish OS 4.5 also adds the ability to use alphanumeric lock codes in conjunction with existing encrypted storage to greatly improve security in the event that a device is lost or stolen.
Sailfish OS 4.5 also has battery aging protection, which users can set to extend the life of the battery and ensure the maximum time between charges over the life of the phone. Overall, the Sailfish OS 4.5 Struven Ketju release includes more than 700 bug fixes and dozens of upstream package updates.
