Galaxy Alpha Marshmallow Update: CM13 and other ROMs

Samsung hasn’t given us any release date yet for the Marshmallow update for Galaxy Alpha. Although we know that device is destined to get it, it would take another 2-3 months at the least, Right now, Samsung is in the middle of upgrading its Galaxy S6 and Note 5 devices to Marshmallow, which are its flagship devices. Generally, the mid-range devices, the A series and E series, get the update around 3 months after the official update rollout is complete for flagship sets of the year.

With Galaxy Alpha Marshmallow update not releasing for your device anytime soon, what do you do if you want it badly. Well, you can install unofficial update, available as custom ROMs, mainly CM13.

Called CyanogenMod 13 in full, it’s one of the most popular custom ROMs available today. You get stock UI of Marshmallow as against bloatware-laden TouchWiz UI from Samsung, which is also one of the main reasons you will love Marshmallow custom ROMs we have shared below.

There is cool set of features that Galaxy Alpha CM13 ROM comes with. You get theme ability and other customization features to tweak your device as per your wishes. CM13 is rapidly updated with latest Android releases, and overall, it will make your device look like Nexus devices which are update directly by Google and come without OEM customization.

The Android 6.0 update will make device’s  battery life better than before, mostly thanks to a new feature called Doze. Under Doze, system manages background process and data even more aggressively when the device is not in use. This feature results in greater standby time by almost two or more times over the Android Lollipop, but that doesn’t mean you will miss out on important notifications — system provides short duration access to apps at limited regular intervals so that apps can sync data and you get notified accordingly.

Previously, users have to agree to all app permissions for install and also for updates, in Android M, users will get notifications asking for permissions only when they are using a particular function in an app.
