  • Hello everyone,

    I’m experiencing a recurring issue with my Formuler Z12 Ultra and I’m wondering if anyone else has the same problem.

    The box is fully updated to the latest firmware, and I have already performed several factory resets, but the issue remains exactly the same

    Whenever I quickly zap through multiple channels without staying on each channel for a few seconds, the box eventually freezes. Once this happens, no channels will open anymore and the only solution is to reboot the device. After restarting, everything works normally again until I start fast channel surfing.

    Interestingly, this only happens when zapping rapidly between channels. If I change channels slowly and stay on each one for a short time, the box works perfectly and never freezes.

    What surprises me is that I also own a Formuler Z11 Pro, using the same setup and provider, and I have never experienced this issue on that device. The Z11 Pro handles fast channel switching without any problems.

    This behavior has been present since day one, even before any updates, and despite factory resets and keeping the box fully updated.

    Has anyone experienced something similar with the Z12 Ultra? Is there a known fix or is this a firmware issue that needs to be addressed?


    Thank you in advance.

  • Are you using MYTVOnline 3 on the Z12 Ultra?

    Please check which version you are using. Also let me know if it is the same version installed on your Z11 Pro.
