Owners of the 2013 Galaxy S4 can now breathe a little sigh of relief, as they can take a look at Android 5.0 Lollipop without having to shell out for a new phone. There’s a leaked Lollipop ROM available for the ageing handset, at version 5.0.1, and as its a leak (not a cobbled together thing from XDA) you can flash it on your device using ODIN and it’ll work pretty well.
Being a leak, there’s probably a couple of untested features or bugs present, but what ROM doesn’t have these? If your phone carks it, it’s your fault for flashing an unofficial software to it, but that said, if you’re game, give it a go and see what you find.
Compatibility wise, it looks like this is only for the i9500 model, which is the international unlocked variant; carrier specific models with slightly different versioning codes may not be supported by this ROM, and so flashing it either won’t work, or may break things.
XDA Developers have the download link, so check it out and let us know what you find.
