For pure speed on extreme low-end hardware, Opera Mini remains the undisputed king.
However, Opera Mini on Android 2.3.6 was not without its challenges and limitations. One of the main issues was compatibility with certain websites. Some websites were not optimized for mobile browsing, which resulted in a subpar user experience.

No amount of clever engineering could stave off obsolescence forever. By 2017, the majority of websites had moved to HTTPS-with-HSTS, requiring robust TLS 1.2 support—something Gingerbread’s outdated security stack could not fully provide. Interactive web applications (e.g., WhatsApp Web, Google Docs) became entirely non-functional. Websites began using feature detection to block older browsers outright. Even Opera Mini’s server-side rendering could not replicate client-side JavaScript-heavy frameworks like React or Angular. Furthermore, the rise of extremely cheap modern Android devices (e.g., the $50 Android 8.1 Go phones) made the Gingerbread+Opera Mini combo less attractive. The final blow came when Opera Software discontinued server support for the legacy OBML format in 2019, effectively bricking the browser on Android 2.3.6.
