The Android Marshmallow-based custom crDroid ROM has been made available to Samsung's 2013 flagship smartphone Galaxy S4 LTE.
The Galaxy S4 series was officially updated to Lollipop OS in early 2015 and is not eligible to get another OS update as it is more than two years old. Samsung has the obligation to provide firmware support for its devices for 18 months (or maximum of 24 months in exceptional cases), after they are released to the market.
Those still hanging on to the former flagship smartphone can upgrade their Galaxy S4s by installing the crDroid custom ROM.
It comes with the Doze power optimization feature, the new "Now on Tap" search option, boot security system, and support for more international languages. In addition to Android M features, crDroid ROM brings new personalisation options and performance-enhancement tweaks.
