List of Best Custom ROM for Lenovo S850 [Updated]

Looking to install a custom ROM on your Lenovo S850? This page lists the best custom ROMs available for the phone. Since the S850 shipped on Android 4.4 KitKat and never got an official update beyond it, a custom ROM is the way to run a much newer version of Android on it.

The Lenovo S850 launched in 2014 with a 5.0-inch HD (720 x 1280) IPS display, a quad-core MediaTek MT6582 processor, 1GB of RAM, and 16GB of storage. These community ROMs can take it well past its stock KitKat software.

What is a custom ROM?

Android is open source, so developers can take the source code and build their own version of the OS. That community build is a custom ROM. It replaces the stock software that came with the phone, usually stripping out carrier and OEM apps for a cleaner experience, and it is often updated with newer Android versions long after the manufacturer stops. See the difference between a stock ROM and a custom ROM for more.
