Samsung finally made commitment to their plan on infusing Galaxy S3 with Galaxy S4 features and the new firmware can be flashed to your device manually.

SamMobile caught the I9300XXUFME3 firmware which runs Android 4.2.2 Jelly Bean for Galaxy S3 and includes some features only found on Galaxy S4. It is still unknown if Samsung will be able to push camera features too from Galaxy S4 on Android 4.2.2 or Android 4.3.

New Features of the Latest Samsung Galaxy S3 firmware

  • Android 4.2.2 Jelly Bean. Build ID: JDQ39
  • New Lock screen from Galaxy S4: Multiple widgets, two unlock effects
  • Improved ripple effect
  • Changeable clock size and personal message on widgets
  • New Screen modes: Adapt Display and Professional Photo
  • Daydream feature
  • Driving mode
  • Actionable notifications
  • New additions to the notification centre.
  • Complete revamped of the Settings UI: Tabbed interface like Galaxy S4
  • New add-ons for Voice control: Control various phone function using voice commands
  • White background on Gallery modes
  • Full screen Samsung apps
  • New S-Voice from Galaxy S4

Warning: The firmware is only PRE-RELEASE and not yet an official from Samsung. It will increase the binary counter of your system but it remains OFFICIAL. The modem on this firmware will remain the same as the previous firmware. This has been fully tested and works perfectly like any other official firmware.
