Galaxy Grand, Samsung’s mid-ranger popped up for the first time back in the year 2013. Samsung flaunted this phone with a 5-inch 480p display. Galaxy Grand caught an 8 MP shooter at its back and 2 MP on the front. A Dual-core CPU clocked at 1.2 GHz was fixed inside alongside a RAM of 1 GB. Galaxy Grand ran on Android 4.1.2 Jelly Bean and was upgraded to Android 4.2.2 Jelly Bean and that’s where its official software support died. Samsung didn’t look back at this device and since then, the only new life this device has been getting is by means of custom ROMs. Earlier we posted a method to update the Galaxy Grand to Android 5.0 Lollipop using a custom ROM as well. Now that Marshmallow custom ROM is available, we will flash this ROM on Galaxy Grand and enjoy the latest and greatest version of Google’s Android OS. Let’s learn a little bit about this AOSP Android 6.0 Marshmallow in order to be able to install it now.

Current version of Android 6.0 Marshmallow AOSP ROM is in the alpha stages. The ROM is expected to be buggy and unstable. The mainstream features like Calls, SMS, Mobile Data, Camera and sensors are found to be working. Some features like FM Radio, Google Play Movies are not working for now. You may flash this ROM on your device just to enjoy the Marshmallow firmware, but it may not be kept as a daily driver. Also make sure that you know how these custom ROMs work and how to handle them. We recommend newbies to be very careful while flashing this ROM. Let’s have a look on the working stuff and the known issues.

What’s working in this AOSP Android 6.0 Marshmallow for Galaxy Grand?

  • RIL (Calls, SMS, Mobile Data)
  • Wi-Fi/Bluetooth
  • Sensors (Accelerometer, Compass, Light, Proximity, etc.)
  • Camera
  • Video (playback & recording)
  • Audio (playback & recording)
  • GPS
  • Everything else not listed under “known issues”

What’s not working?

  • AOSP keyboard does not support gesture typing even with gapps installed. This is to prevent crash with not fully compatible gapps packages. If you want gesture typing, install Google Keyboard from the Play Store.
  • Google Play Movies (widevine DRM) does not work
  • FM Radio does not work
  • SELinux is in permissive mode
  • Runtime storage permission does not work properly (setns patches are not applied, see PermissionsHostTest CTS test)
  • Sometimes wake up causes music stutter
