[Galaxy Grand Duos i9082 Android Development] pawitp:
This is a build of the Android Open Source Project (AOSP) based on Android 6.0.0 for people who prepare pure Android without the extra feature of CyanogenMod or other ROMs.

Due to having less free time and losing interest in custom ROM development, this ROM will no longer be updated.

Everything else not listed under "known issues"

Known Issues

AOSP keyboard does not support gesture typing even with gapps installed. This is to prevent crash with incompatible gapps packages. If you want gesture typing, install Google Keyboard from the Play Store.

FM Radio does not work

Runtime storage permission does not fully work (setns kernel patches are not applied, see com.android.cts.appsecurity.PermissionsHostTest#testInteractiveGrant CTS test. After granting permission, the app will need to be restarted before it sees the new permission.)

Sometimes wake up causes music stutter

Does not work on 4.1 stock ROM's bootloader, please upgrade to stock 4.2 before flashing

Additionally, Dual SIM has the following limitations (once they work):

Both SIMs are always enabled (no way to disable one SIM)

"Receive incoming call while data is enabled" is always enabled

Installation

Make a backup!

If you were on CM 10.1 or a stock ROM prior to 4.2, upgrade to stock 4.2 first.

Install ClockworkMod recovery with SELinux support (.tar) (.zip). Older CWM will result in a "status 7" error.

Reboot into recovery

If you are using a recovery which mounts /system on boot, unmount it before installing

Wipe data if coming from stock or other ROMs (You may get a "status 7" error if you fail to wipe.)

Install the ROM

Optionally install the Google Apps Addon (In Marshmallow, you MUST flash gapps before booting into the system for the first time or else the proper permissions will not be granted resulting in Setup Wizard crash. If you experience the crash, you will need to do a factory reset.)

To upgrade to a newer build, simply flash the zip. You also need to flash Google Apps and other addons again because addon.d support is not included in this ROM.

FAQ

Can you include the "ask first" option for sending messages?

The "ask first" option is not available in AOSP. However, you can select the SIM when you send the message if you use Google's Messenger app.

Sometimes the people on the other side of the call cannot hear me

The real cause of this is unknown, but this is often found with people using the I9082DDUBNB1 baseband/modem. Some people have reported that flashing a different baseband (e.g. I9082XXUBMK3) has resolved the problem. A collection of basebands can be found at http://xdaforums.com/showthread.php?t=2496989. Or you can also try I9082LUBUBMK1 that I use.

How do I enable/disable Dual SIM?

Dual SIM support is enabled by default (except for 20151018 build). If you only use 1 SIM and wants to disable Dual SIM support, you can use the following instruction:

Enable:

su
setprop persist.radio.multisim.config dsds

Disable:

su
setprop persist.radio.multisim.config none

(Instruction screenshots)

Battery Statistics shows that Wi-Fi is always on even though I've turned it off.

If you are using "scanning always available" in Advanced Wi-Fi Settings, then Wi-Fi will always be on to scan for available network to aid location discovery.

How do I enable root?

Root need to be flashed manually.

I'm having battery issues

After installing, my storage was reduced from 8 GB to 4 GB

You only have 4 GB for user data in the first place. The other 4 GB is used by system files. This is the same with stock as well. However, stock might have displayed it as "8 GB with 4 GB used by system files", but AOSP-based ROMs will only display the space available for user data.

Can you include Feature X into your ROM?

No. This ROM will have AOSP's feature set.

Can you include S-Note/S-Planner/MultiWindow/Insert Samsung App Here?

No. This is an AOSP ROM and cannot have TouchWiz applications.

Can you include call recording?

No.

What kernel does this ROM use?

A slightly modified version of the stock kernel, the source code is linked above.

I've heard that Broadcom doesn't release source, how can you make this ROM?

Contrary to the popular belief, userspace driver source code is not always required to make an AOSP-based ROM as long as the proprietary binaries shipped with the device does not modify the API too heavily (or is from a very different version of Android). Instead of modifying the source code of the drivers, the Android source code was adapted to be able to use the proprietary binaries.

Can I use your ROM as a base?

http://source.android.com/source/licenses.html

Most of Android is licensed under the Apache License with other small parts licensed under other open-source licenses. Which means that you may modify and redistribute without asking for permission as long as the proper credits is given.

Can contacts be saved to phone/SIM?

No. It is not supported in AOSP-based ROMs.

Can I send files over Wi-Fi Direct?

Yes, but you must use third-party applications. The implementation provided on Samsung ROMs is not an open standard. AOSP/CM does not provide a native way to send files over Wi-Fi Direct.

Can I mirror your ROM?

You're free to, but I will not list it in this post.

You are free to discuss bugs in this thread. However, I will not actively fix or help with bugs reported. Patches which fix them are welcomed.
