Get Android 5.0 Lollipop experience on your Galaxy S5 with CM12 ROM

We can understand the eagerness of Galaxy S5 users wanting an stock Android 5.0 Lollipop based ROM. Samsung’s stock UI, TouchWiz, is horrendous and even on the leaked Android 5.0 Lollipop update for Galaxy S5 it looks bad. This goes to show Samsung still isn’t listening to its users for providing near stock UI feel on for its devices.

Anyway, thanks to albinoman887 over XDA for bringing CM12 a.k.a CyanogenMod 12 to Galaxy S5, giving you and millions of other Galaxy S5 users a chance to experience Android 5.0 Lollipop update in pure Google flavor. CyanogenMod is popular custom ROM that’s completely based on stock Android UI, with added features and options, and CM12 is the Android 5.0 Lollipop flavor of the ROM.

At the core, CM12 is maintained by the CyanogenMod team. And as per the CM team, CM12 is yet to be complete, many CyanogenMod features users love to use aren’t yet available on the CM12. The team is looking at options to bring those features to the material design language of Android 5.0.

Galaxy S5 is expected to receive Android 5.0 Lollipop update officially from Samsung in December 2014. And the carrier branded variants of Galaxy S5 will receive the update in January 2015. So until then, CM12 is your best bet to get Android 5.0 Lollipop on your Galaxy S5.

CM12 is an AOSP based ROM, so you won’t have fancy features like Fingerprint scanner or Heartbeat sensor on your Galaxy S5 if you chose to install CM12. But we guess, you could do away with them, those aren’t any must-have features and using those features at the cost missing Android 5.0 Lollipop doesn’t makes sense.

We’re covering this CM12 ROM for Galaxy S5 a bit late, it’s has already been out for enough days that devs have already resolved most bugs/incompatibility issue on the ROM. Although still in Alpha stage, everything seems to be working on Galaxy S5 CM12 ROM. Great work devs!

The only issues present on this CM12 ROM are things like touchscreen not working on some games and SystemUI force closes sometimes but it’s not specific to Galaxy S5 only, it’s a CM12 issue present in all device the ROM is available for.

Also, know that this CM12 ROM for Galaxy S5 isn’t coming from the CM team directly. It’s an unofficial port from the CM12 device tree. Official CM12 nightlles are expected to release by Dec. 2014, but we guess nightlies will come first for Nexus devices only. For the Galaxy S5, CM12 nightlies may come by the end of Dec. 2012 or early in January 2015.

Enough talk? Okay, let’s hit the downloads section and flash CM12 on your Galaxy S5.

    I love your opinion of TouchWiz as “horrendous”. Its completely objective.

    I have used CM for years and still use stock android on a MotoX, but I like my S5 the way it is. It works well and has no lag what so ever. If the transitions are slow, you can change them in developer settings.

    I think stock is great, but it is also lacking good software add-ons. Some things are getting better (camera) but the intentional minimization does get old after a while.

      Just make it look cool and I’m all praise for TouchWiz. Features and software add-ons are good on Samsung devices, no doubt about that.
