    Hello Guys,

    i bought 2 of these bracelets, one has low bright screen and long battery and the other is brighter and it barely lasts 1 day..

    I had firmware version 2.2 , I noticed that changing main screen ( the one that shows time, steps , calories etc) with the simple clock it now lasts half day more.

    I have downgrade the firmware to the version 1.7 and i am checking if the battery lasts bit more with the main screen with all the data… but i am afraid that it will not change anything.

    Please is there any solution? modify bright or something?

      Hello Juan, it seems that it is not the firmware issue, but the battery. If the old version doesn’t work for you, then this is the battery problem. I can’t help you please turn to the seller for help. :/

    FunDo presents a problem when it loses connection to the F4 (for example, when the F4 runs out of battery).
    I think FunDo is continually trying to reconnect and consume all the phone’s battery.
    Thank you.

    I want to know if it is possible to modify the brightness of the screen of the F4, which is quite low.
    And I want to offer myself to improve the Spanish translation, which now has many errors.
    Thank you.

      Hello Jose, sorry, firmware update can’t improve the brightness. About the translation, thanks, I’ll ask our engineers whether we can change the translation. 🙂

      What’s your F4 firmware version? And app version? Reset the F4, try again.

        I have now FW version 0.1.8 and App version 1.2.4.
        After restarts and bindings it is still same. On “Firmware upgrade” screen is shown 0% and on the phone notification bar is line “Upload failed / DFU process failed”.

    Hi, I updated the firmware from 0.1.8 version to the latest. My issue is that now the height in outdoor menu is not being displayed correctly now. Earlier it was 222 m and now it’s incorrect 2170 m. I am running Android Nougat, latest version of Fundo Pro, Xiaomi Redmi 4x

    I just update my F4 but the double click to exit the swimming mode isn’t the solution. The device isn’t able to register all the swimming session.

      Yes, Pannato. I just replied this question. 🙁 Too bad. We’ll keep on working.

    I’ve just updated it from in-stock 0.1.8 version and seen the improvements.
    I’d like to ask a question. Does “Auto wake up on hand flip” function work on this firmware? Because mine didn’t work since I bought. Is it only on mine or needed to upgrade future firmware? Best

        I think it does. It count some steps and show in FunDo app.
