Samsung Galaxy S3 update: Samsung Galaxy S3 I9300 may now upgrade to Android 4.4.4 Kitkat. According to International Business Times, ParanoidAndroid (PA) 4.42 Final ROM brings the latest Kitkat features based on Android 4.4.4 KitKat stock firmware which includes redesigned volume panel, improved Hover UI/UX interface for smartphones and tablets, PIE controls and PEEK, new improved theme engine, battery tile and status indicator, new support for colourised themes, revamped recent menu, improved Documents UI system API and bug fixes and a handful of system tweaks.

Here are the pre requisites before installing Android 4.4.4 Kitkat:

• The ParanoidAndroid ROM and the instructions given in this guide are meant for the Galaxy S3 I9300 model only. Verify device model number by navigating to Settings > About Phone/Tablet.
• Back up data and settings using a recommended custom recovery tool, like ClockworkMod (CWM) or TWRP, as it creates a complete image of the existing phone setup. In Recovery, choose Backup and Restore and tap Backup.
• Verify correct USB drivers for the phone are installed on the computer (download necessary USB drivers from manufacturer's website).
• Ensure USB debugging mode is enabled on the device, by navigating to Settings > Developer Options (NOTE: Tap the phone's Build Number seven times to unlock or reveal the hidden Developer Options under Settings.) Then select the checkbox to enable USB debugging mode under Settings > Developer Options.
• Make sure the device has at least 80% battery charge to prevent unexpected device shutdown (due to battery drain) while installing the ROM.
• Ensure the device is unlocked (not locked to a specific carrier) and rooted with latest ClockworkMod (CWM) Recovery (v6.0.4.5) installed.
• If the device is stuck at booting or experiencing boot loop issues, perform Wipe Cache Partition and Wipe Dalvik Cache a few more times before rebooting.
• Allow newly installed ROM to stabilise for five minutes before you start working on it.
