The Samsung galaxy s3 i9300(International version) was one of the best galaxy phones then and it’s still trending. It came with android 4.0.4(ICS) out of the box. Android 4.3(Jellybean) update later came with some serious bugs. Actually Samsung no longer roll out OTA updates to the galaxy s3 i9300.

“Most of its attractive features are its 1GB RAM, 16GB ROM, AMOLED screen with very deep black and saturated colors, great battery life, very powerful and crystal clear imaging, good sound enhancement and other cool features. What I personally love most is its display quality.I can’t stop watching HD videos on my S3”

So if you are just getting the Samsung S3(i9300), and you are still on stock os, I have good news for you. There are so many things you will enjoy after these.

Having used the galaxy s3 international version, I always switch from one custom ROM to the other. Why? they weren’t satisfying me in some ways.

It’s either battery issue, display going off sometimes, camera not coming up. I finally found the best, flawless, efficient and user-friendly ROM which any s3 i9300 owner can install right away and use it as a daily driver.
