Install OmniROM 5.0 Lollipop on Samsung Galaxy S2 GT-I9100

Download and install OmniROM 5.0 based on Android 5.0 Lollipop on your Samsung Galaxy S2. If there’s only one reason why Android is so popular today is because of the Samsung Galaxy S2. When the S2 was released, it had Android 2.3 Gingerbread.

At that time, Android wasn’t as popular as today. back in 2011, dual core processor clocked at 1.2 GHz, 1 GB RAM, 8 MP camera and Super AMOLED display were specifications that only the Galaxy S2 had. At that time, there was no competition and that allowed Samsung to sell more than 20 million units.

But the first ROM that was able to create a working build of Android 5.0 Lollipop was OmniROM. And today, OmniROM comes with a great news for all Galaxy S2 GT-I9100 users.

OmniROM based on 5.0 Lollipop has come the Galaxy S2. Even though the phone doesn’t have the best specifications, it is still able to run Lollipop fine without any major problems. That is a big surprise considering that Samsung never updated the phone to 4.4 KitKat, let alone Lollipop.

But thanks to the amazing developers, everyone who has a Galaxy S2 GT-I9100 variant, can install OmniROM and enjoy Lollipop OS.

The developer says that it is quite a stable build considering that is the first version, but it isn’t stable enough as a daily driver. Camera, bluetooth, kernel, vibration, sound, recovery and RIL are all working. But there are a few apps that aren’t working at the moment.
