I have Karbonn Android one phone. It is updated to Lollipop 5.1. I read that multi-user option is available in Lollipop. But in Settings the Users option is not available.

How can I enable it? Is it not supported by Android one phones?

You can enable multiuser support without rooting the device by using ADB.

  1. Enable debug mode (developer settings)
  2. Connect the device via USB to a PC with ADB installed.
  3. Execute these commands:

    adb shell setprop fw.show_multiuserui 1  
    adb shell setprop fw.max_users 4  

The settings might be lost after reboot. I'm sure it's possible to modify the build.prop file from ADB too, but I'm not that experienced yet.

    @Bert, yes it is possible to modify build.prop file from adb, but you need root access to do this :)

It is supported, but you must have rooted device.

Download file manager that allows root access(for example: ES File Explorer)

Navigate to /system/

Backup build.prop

Add these lines at the end of build.prop file:



Save and reboot device

If something went wrong, restore build.prop backuped version from recovery.

  • Thanks, it worked excellent on my Moto G 2nd gen XT1079, stock Lollipop 5.0.2!

It can be enabled without rooting.

You must have JDK (including platform tools) and proper ADB drivers installed.

  1. First, download TWRP Recovery for Android one (sprout) and paste it in
    c\program files\andrdk\platform-tools. Rename it to "twrp".
  2. Connect your device.
  3. Right click on platform-tools folder holding left-shift and click on "Open command window from here".
  4. Type adb reboot bootloader -- this will boot phone into fastboot mode.

    Then type fastboot boot twrp.img -- this will boot the device into TWRP recovery temporarily.

  5. In recovery click mount, then check system.
  6. Type adb pull /system/build.prop -- this will copy the build.prop into the platform-tools folder.
  7. Open the build.prop file using notepad++ (simple notepad may corrupt the file), add the following two lines at the bottom and then save it:

  8. Type adb push build.prop /system/ -- this will push the edited file.

  9. Now type

    adb shell
    cd system
    chmod 644 build.prop
  10. And finally, go back to recovery using navigation key and click reboot then click system.

Now, you have enabled multiuser without root.

NOTE: Do everything at your own risk. I will not be responsible for any damage to your device.

I posted this because this worked for my Android one.

    fastboot boot twrp.img -- does Android one comes with unlocked bootloader or did you unlock your device sometime ago?

Some models don't support that feature and your phone is one of them.

    The link some phones have this feature disabled, which can still be enabled if you root them - which is not the same as they don't support it at all.
