Samsung Galaxy S3 News Update: Samsung officially stopped the software service support to the Galaxy S3 with Exynos chipset due to lack of RAM capacity according to IBT. Users can now update their I9300 by installing custom ROM such as NeatROM. The NeatROM v6 (4.4.4) custom firmware is based on the AOSP (Android Open Source Project) v4.4.4 KitKat OS and is said to bring customisation options to boost device performance, new visual interface, easy access to key apps and loads of personalisation options.

Following are the things to remember before installing Custom ROM in to the device:

• Though installing custom ROM improve the device's performance and UI experiences, it makes the company warranty void and they will no longer be liable to provide updates in future [users can restore warranty by flashing the device with stock-ROM].
• Make sure the device is rooted before going forward for custom ROM installation
• This Android 4.4.4 KitKat NeatROM custom firmware has to be installed on the Samsung Galaxy S3 GT-I9300 (Exynos chipset) only; if tried on other devices, it might get bricked [To check your device model: Go to Settings >> About phone >> model number]
• Installation of custom ROM requires clearing of memory in the smartphone, so make sure to back all the data by installing Clockwork Mod (CWM) Recovery/ TWRP in the smartphone.
• Users make sure they have installed USB drivers on the PC, or else your phone (Samsung Galaxy S3 GT-I9300) smartphone will not be recognised by the computer.
• Make sure your device has more than 80 percent battery, or else there is chance of smartphone getting temporarily bricked if the installation process is interrupted in the mid-way.

Note: This ROM updates are not coming from Samsung and have nothing to do with the already mentioned company. This report is only made to inform users of possible updates and this site is not liable for any damages that these installations may cause.
