What is this?
This is CyanogenMod 12 (based on JustArchi/arter97) with many features from the well known CM12S/Cyanogen OS 12 and CM11S made for the OnePlus One. All Apps are successfully ported from CM11S for the i9300 Galaxy S3 and much more (read at features). The OnePlus One has a great Rom and why not giving the features to you all? That's the great reason why there is now CM12S for the S3.
The Rom has all features from Official CM12 and much more features are added, too.
I am only the Publisher of the CM12.1 based rom! Keep in note that Kevin210898 is the developer. I am helping him with support and more! So if you have probelms ask me. I have also contact to the dev.

Wipe cache, dalvik and flash the update.zip.
How to improve the battery:
- Try Calkilin Play Service Fix
- Flash NITRO X SPARK [dont know if it brings bugs
- Use your Kernel App
- Please refrain from talking about other kernels than stock. We can't track every kernel and it's problems, hence, you're using other kernels at your own risk. Please don't report bugs while you're using custom kernels. Only Kernel with help is stock and Boeffla Kernel Alpha 4 or newer!
- Official Google Plus Community for better support and help!
- TWRP Recovery is highly recommended for use! CWM is out of date and not made for Android 5.X
- This Rom gets every month one stable update with newest features, bug fixes and more improvements
- I don't allow you to publish direct download links to my Rom on other sides or threads! Always use the link of this xda thread somewhere else, no direct download link! (If you still need to make it, please talk with me before!!)
It is also NOT allowed to copy and paste my whole written text for this project on your/other websites!
Your warranty is now void.
I am not responsible for bricked devices, dead SD cards,
thermonuclear war, or you getting fired because the alarm app failed. Please
do some research if you have any concerns about features included in this ROM
before flashing it! YOU are choosing to make these modifications,
and if you point the finger at me for messing up your device,
I will laugh at you. Hard. A lot.
