    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.

    Thank you for your reply.

    I purchased my Formuler Z12 Ultra from the official Amazon store. When I received it, MyTVOnline 3 was not installed and it was not even available for download in the App Store. After several updates, I was finally able to install it.

    The version I am currently running is MyTVOnline 3 v12.1.36-5048-994217d35.

    I have already tried clearing the cache, performing factory resets, and setting up the device from scratch multiple times, but the problem remains exactly the same.

    The issue only occurs when I perform rapid channel zapping through multiple channels. After switching quickly between channels, the box eventually freezes and no channels will play until I reboot the device. If I change channels slowly and allow each channel a few seconds to load, everything works perfectly without any issues.

    At first, I assumed this was a software issue that would be fixed in a future update. That is why I decided not to return the device immediately, especially since Amazon allows returns. However, after several months and without seeing any update that addresses this problem, I am starting to consider returning the Z12 Ultra and continuing to use only my Z11 Pro, which has never shown this behavior under the exact same conditions.

    Has Formuler identified this issue, or is there anything else I can test before deciding whether to keep or return the device?

    thank you for you answer
