cyanogenmod 12 android 5.0.2 lollipop

If you are a Samsung Galaxy S3 GT-I9300 owner who has been using CyanogenMod 12 to enjoy Android 5.0 Lollipop, then we have some good news for you. CM12 for the Galaxy S3 has been available since early November and all users have been able to enjoy Lollipop for more than one month.

During this month, the ROM was in Alpha state which means a regular user shouldn’t install it as it is aimed towards experienced users who know how to install custom ROMs. Since the ROM was in Alpha stage all this month, it contained a lot of bugs.

When the first Alpha build was released a few weeks ago, things like WiFi, camera, 3G/4G mobile data, RIL and calls weren’t working.

The developer of the ROM, JustArchi, has now released the first Beta build of CyanogenMod 12 for the Samsung Galaxy S3. Beta means that the ROM is close to being stable.

Every ROM goes through three phases: Alpha, Beta and Stable. Alpha is the earliest phase and the ROM is usually full of bugs and it is not intended for normal users.

On Beta, most bugs are fixed but there might be some that developer hasn’t noticed or hasn’t been able to fix. Stable is the latest phase of the ROM. Every bug is fixed and all users can install it.

Benchmark Test

    According to my tests, I think the contacts portion should be checked as it mostly deletes the saved contacts, I am using import from SIM to gain them back……sharing it to help you resolve this issue on stable version.
