The Android 5.0.2 Lollipop update was released late in December and is intended to deliver a number of crucial fixes that address serious Android 5.0 bugs that range from random crashes, Wi-Fi issues, and poor battery life. Now, a version of Android 5.0.2 Lollipop custom ROM is available via CyanogenMod 12 nightly.

“We would like to note that at this point we consider ourselves 85% complete for our initial CM12 M release. We’ll spend the remainder of this month bringing up additional devices and finishing up the features you’ve come to love from CM11 – implementing them into the new Material UI,” according to a post on the official website of CyanogenMod.

Even though CyanogenMod's statement confirms that we still have another month before the Lollipop-based CM12 M is ready for release, the CyanogenMod 12 nightly builds will be available in 31 devices, which are listed here.

For now, we are sharing a tutorial on how to download Android 5.0.2 Lollipop custom ROM for the Samsung S5 LTE.
