CyanogenMod 12 ROM 5.0 Lollipop for Samsung Galaxy S3

The Samsung Galaxy S3 is undoubtedly the best phone Samsung has ever created. Even though today it doesn’t have the best specifications on the market since it is 2 years old, it was one of the fastest smartphones back in 2012.

With a quad-core 1.4 GHz Exynos processor, Mali 400 GPU, 1 GB RAM, HD 4.8″ Super AMOLED screen and 2100 mAh battery, it was one of the best smartphones you could ever buy.

Even today, it is Samsung’s most sold smartphone ever, selling millions of devices in a single month. Because of this, the Samsung Galaxy S3 has a huge fan base with millions of people still using the phone.

There are a lot of developers creating ROMs, kernels and mods for the phone. Some of these developers are JustArchi and Arter97. These two developers have done a lot of amazing things in the past, and now they come with another creation.

A few days ago, we saw a beta build of Android 5.0 Lollipop AOSP ROM on the Samsung Galaxy S3. Today, another ROM has been created for the phone and it is the CyanogenMod 12.

CyanogenMod is one of the most popular ROMs for Android devices. It is stable, fast and gets updated often. JustArchi has been able to port the CyanogenMod 12 ROM on the Samsung Galaxy S3.

Of course, as with the other ROM, CM12 is not stable. It has a lot of bugs and it is designed for testing purposes only. But if you want, you can install it on your phone right now. The installation process is simple.

      Is there anything we can do about it (in the configuration)? …or its something that has to be changed on the ROM? Thanks a lot!

  2. PHONE IS WORKING? oh and can i install google apps? and if i already have cyanongenmod can i just update without wipe data?
