Samsung is unlikely to release the latest Android 6.0 Marshmallow update for its former flagship phone, the Galaxy S5, anytime soon. However, owners of the Galaxy S5 are in for some good news, as the industrious CyanogenMod developers have unleashed the CyanogenMod 13 (CM13) ROM to bring the first Marshmallow custom update for the device.

As the ROM is still an early release, it may harbour a few inherent bugs or broken features that will be fixed in the forthcoming updates to CM13 firmware. Expect some stability improvements to this ROM with subsequent updates from the CyanogenMod team.

Working features: Built from CM source, Service, Text, Data, Call, Audio, WiFi, Google Now, Bluetooth and more.
