Galaxy S2 (2011) receives unofficial Android 11 update The smartphone market was much different nine years ago. Apple was still collecting the fruits as a predominant smartphone company, while other companies were trying to catch with a still lackluster Android OS. Samsung was in the beginning of a successful route that took it to the lead of the smartphone market. In 2011, the company unveiled its “flagship” dubbed Galaxy S2, or Galaxy SII if you prefer. The device arrived at the Mobile World Congress in February 2011 as a direct sequel to the original Galaxy S. Android 11 arrives for the Galaxy S2 The handset debuted with the non-appealing Android 2.3 Gingerbread. The device got Android 4.1.2 as its last official update. You may think that all Galaxy S2 units out there are buried and left behind. Nah, this isn’t the case when you have an active Android community full of enthusiasts. The device is popular among developers and over 9 years after its released, some interested owners can now flash Android 11 on the handset.
