However, the exclusivity masks severe compromises. Due to the hacked driver stack, GPU-accelerated rendering often failed, causing UI stutter or app crashes. Hardware video decoding (H.265) was frequently broken, forcing reliance on power-hungry software decoding. Wi-Fi and Bluetooth drivers, originally written for Android 4.4, required unstable shims, leading to random disconnections. In many builds, deep sleep functionality was disabled to prevent system-on-a-chip (SoC) wake failures, decimating battery life in portable devices. Thus, this firmware is not a daily driver but a proof of concept —a testament to engineering persistence rather than practical usability.

Flashing firmware, especially an "exclusive" or modified version, carries risks.
