Ever since Google launched Android 5.0 Lollipop many manufacturers have announced their Lollipop plans, in other words, when will they devices receive the newest update of Google's operating system. Google is currently pushing Lollipop OTA (Over-The-Air) updates to its older Nexus devices and Motorola is doing the same for select devices. Samsung was amongst the manufacturers that promised Lollipop updates for some of their devices and knowing this Korean tech giant they will deliver them relatively soon, Samsung was always rather fast when it comes to updating their relatively heavy TouchWiz skin. We've already seen leaked builds on both the Galaxy S4 and the Galaxy S5, courtesy of SamMobile, and now we have something that will appeal to those of you who like to flash stuff on your devices.
Unofficial AOSP Android 5.0 Lollipop builds landed for Samsung Galaxy S4 and Galaxy S5. Several Galaxy S5 variants (SM-G900I, SM-G0900F and SM-G900M) and the Qualcomm version of the Galaxy S4 (GT-I9505) can now taste some sweet Lollipop software in case you want to flash it of course. If you'd like to get the software and flash it on your device, visit this link for the Galaxy S5 builds and this link for the Galaxy S4 builds. These links will take you to XDA Developers webpage where you can download what you need. All these builds are based on AOSP and an alpha CyanogenMod 12 build though, so keep that in mind. Many things may not work and of course there's always a chance you'll brick your device or something similar to that. Galaxy S5 build is somewhat more stable according to XDA, only the camera and NFC are not working it seems. As far as the Galaxy S4 build goes, that's a completely different story. External storage, GPS, IR blaster, NFC, IRL and sound are not working at the moment.
These builds are, of course, not meant to be installed on your daily drivers, but if you're willing to take a shot an install it on your second device or something, feel free to do so. We do not recommend you to do that if you don't have any experience with the procedure.
