The Samsung Galaxy S2 was released many years ago and at that time it was one of the best smartphones in the world. It was manufactured by Samsung in order to compete with the hot-selling Apple iPhone at that moment. The device tried but wasn’t able to surpass the performance of the iPhone. Since then, the company has released many different flagship devices like the S3, S4, S5 and currently the S6 and S6 Edge.
Today, the Samsung Galaxy S6 is one of the most powerful devices in the world, but a huge mass of iPhone fans continue to disregard any of its features. As a result, Samsung is still a little behind in terms of worldwide smartphone popularity. Although the Samsung Galaxy S2 is an old phone, it still has plenty of followers, fans and users worldwide. They keep adding the custom firmware and user interfaces all the time.
When you add new software or UI to your device, it leads to a high level of risk and can void your warranty. As a result, you need to be aware of it before you upgrade the software. Nevertheless, earlier this week, it was announced that you can now install the latest Android Lollipop 5.1 on your Samsung Galaxy S2. This new software is completely based on the OmniROM firmware; hence it’s a prerequisite to downloading the Android 5.1 software. Similar to any other custom software on the market, you need to backup and save all of your essential data on the phone before going for the update.
Since you are adding custom software, you can never be sure of the result. However, your Samsung Galaxy S2 needs to be rooted and unlocked and needs a recovery tool installed as well. Before you start the install, you need to make sure that the device has 60% power. You need to know about the features you’ll be dealing with, before upgrading to Android Lollipop 5.1 OS.
