Android 4.3 firmware for Samsung Galaxy S4 GT-I9505 leaked. Firmware name: I9505XXUEMI8

An official Android 4.3 firmware I9505XXUEMI8 for the Samsung Galaxy S4 GT-I9505 has leaked on the internet and is available for download for everyone.

Android 4.3 was released by Google in the last week of July and this first leak of Android 4.3 for Galaxy S4 is coming after 2 months of Google’s announcements. We weren’t expecting it any time sooner than now, but considering the fact that Android 4.3 was actually an small update to Android OS, it’d have been better if Samsung had prepared the firmware quicker and earlier. Because it’s going to take Samsung another month now to officially release Android 4.3 firmware for Galaxy S4 devices across the globe and by that time the release of Android 4.4 would be closer, which is far more important update than Android 4.3.

Anyway, coming back to the topic, this Android 4.3 firmware ─ I9505XXUEMI8 which got leaked may not be perfect for everyone to install. Although majority of users are reporting smooth operation of the firmware but some users also encountered issues with WiFi connectivity and phone’s performance in general.
