It is technically possible to run Android 13 on a Samsung Galaxy S2 using free, open-source software (Heimdall + TWRP + LineageOS 20 unofficial). However, the result is a slow, unstable, and insecure system unsuitable for daily use. The exercise demonstrates the impressive longevity of open-source driver backporting but also the hard limits of 1 GB RAM and a 2011 GPU.
For users seeking a free modern OS on the Galaxy S2, Android 11 (LineageOS 18.1) offers a far better balance of features and performance. Android 13 remains a proof-of-concept, not a practical upgrade.
If you search for "Samsung Galaxy S2 Android 13 free," the only serious answer is LineageOS 20. LineageOS is the successor to the famous CyanogenMod. It is the most stable, widely used custom ROM in the world.
Thanks to a dedicated developer known as "rINanDO" (and the legacy team at the Galaxy S2 Unified Development forum on XDA), there is an official build of LineageOS 20 for the GT-I9100.
Yes, you can run a free, unofficial, and very buggy version of Android 13 on a Samsung Galaxy S2 as a tech demo or hobby project. But for a usable smartphone experience, stick to lightweight Linux-based alternatives (like postmarketOS) or keep the S2 on its original Jelly Bean for retro gaming.

The Samsung Galaxy S2 (GT-I9100) is, without a doubt, one of the most iconic smartphones ever created. Released back in 2011, it was the device that dethroned the iPhone 4S in many markets. With its stunning (for the time) 4.3-inch Super AMOLED display, 1.2GHz dual-core Exynos processor, and slim profile, it was a powerhouse.
