Sammobile has worked out how you can try the Samsung-sanctioned update for yourself ahead of its official roll out.
The firmware is dated October 8 so it's basically what R Kelly would describe as hot and fresh out the kitchen.
S4 users can install the leaked software update by following the instructions over on Sammobile but be warned that you do so at your own risk and you could well end up wiping all your data and bricking your handset.
Once Samsung is happy with the software, network-free Galaxy S4s should receive the update fairly quickly; locked handsets will have to hang on until the networks give the go ahead.
- That's all well and good but we're ready for a new version of Android to launch - good job Android 4.4 KitKat is likely to be unveiled later this week.
