If you are still on older Lollipop or older Marshmallow ROM, you should definitely check out the latest Resurrection Remix ROM as it brings a ton of new features your Galaxy S5 needs.
Based on latest Android 6.0.1, the Resurrection Remix ROM gives you full fingerprint support. Not only that, it makes it better than stock TouchWiz since fingerprint works without having to turn the screen on. Simply swipe your finger and your phone will unlock, just like newer Nexus 6P or 5X. I find this alone worth installing the ROM.
Antutu scores on Android 6.0.1 Marshmallow: 49,340
Performance is also excellent on this ROM, bringing you all the new speed enhancements of Marshmallow. Antutu scores are very high scoring near 50K (that’s performance of a stock Note 4 which has faster processor) and most importantly, the ROM is fast when using it.
But the fun doesn’t stop there, unlike CM13, Resurrection Remix brings you an endless number of customization that you can play with all day long (literally). Customizing your status bar, notification drawer, quick settings panel, navigation bar, recents, and simply having the best AOSP customization is backed right into the ROM.
