However, as the device matured, the firmware updates began to highlight the hardware's limitations rather than hide them. The Mi TV 4A Pro 32 is powered by a quad-core processor and equipped with a modest 1GB of RAM—a standard specification for budget TVs of its era. As firmware updates increased the size and complexity of the operating system, the hardware began to struggle.
Another critical aspect of the firmware saga is the stagnation of Android versions. While the TV runs on Android TV (or a hybrid of Android TV and PatchWall), the firmware updates rarely delivered major Android OS version upgrades. Users largely remained stuck on older versions of Android (primarily Oreo or Pie), missing out on the interface improvements and efficiency optimizations found in newer Android builds. This discrepancy highlights a major issue in the TV industry: the disconnect between security patches and OS upgrades. Xiaomi provided sporadic security updates to claim the device was "supported," but the core operating system remained stagnant, leaving users with an aging software experience. firmware update on xiaomi mi tv 4a pro 32 hot
