Attention! I received many complaints about the new firmware 0.2.2 and some users reported that all these features worked well in 0.1.8 version. Actually you can download the 0.1.8 version and make a firmware update manually. Here is the tutorial. http://www.chinawatchs.com/how-to-update-the-f4-firmware-manually/ You can find the tool and firmware there.

    Hi, i just bought a new brand F4 smartband. I plugged it on charger and it has been flicking with a half battery and it vibrates, it has been doing this for 3 hours. Is this normal for new band or it is faulty? Please assist.

    And is the BP monitor accurate?

      Hello Ishmael, did you try to unplug and replug on charger or shut it down and charge it again? Does it make any difference?

    My 2 year old baby threw away USB charging cable and now I can not charge my no.1 f4 smart band and use it. I have bought this smart band on gearbest.com but they do not want to give me the after-sale support. I was open a ticket WT17101902566, but they sayed to me that: “…the cable cannot be shipped anymore because of stock issue…”. Where I can get this USB carging cable and how much it will be cost for me if it will send to Russia?

    Good day. The aplication ver.1.2.6. The report tab: in the graphs steeps there is no information the y-axis. For this it is not clear how many steps completed in each time period. X-axis information is not enough, time stamps are placed too far away, would the difference not 12 hours but at least 3. Please set it not 0.00-12.00-23.59, but 0-3-6-9-12-15-18-21-23. Scrolling is very bad, graphics jumping when scrolling, please fix it. And need to do the battery charging display bracelet percentage in the application, so as now to know if the charge is still at least two days is not possible. Thank you.

    Hi Jon,

    I have the Fitness bracelet for a few weeks now and would like to feedback my comments for your consideration.
    I am in UK and weather and outdoor measurements seem to work okay here.
    The upgrades in software have certainly improved the functions and it is good to see you respond to users views and suggestions.
    My comments below:
    Smartband ver 0.2.2
    The Dial function should be moved under the Settings menu. It is too easy to modify the dial when you don’t intend to.
    The Stopwatch should be moved from the settings to Level 1 menu
    Weather.. Altitude shows 324m actual altitude 19m.
    Fundo Pro App v 1.2.5
    The activities on the watch, running, cycling, badminton etc. do not match activities in the App walking,running moutaineering etc.
    Heart Rate test is working but can’t it also do blood pressure on same test and record results.
    The Pulse BP on BP screen is not the correct Pulse as shown on the Heart screen
    Sleep Screen – Can you have option to change Sleep sensing from 21:00 to 09:00 to 23:00 to 11:00

    One minor problem with the bracelet.. when I play Squash and my wrist is hot and sweaty it seems the bracelet expands and the face comes off the bracelet and falls onto the floor. I have had to glue it into the bracelet and that seems to be working.
    Thats it for now, keep up the good work on this great little device

    Thanks
    Mike

    After updating the firmware of the bracelet to version 0.2.2 it became much better, and the application with the translation into Russian and stability looks better, but there are many more critical comments:
    The Fundo application:
    1) Make a good translation into Russian, for example you can take the version translated by the user from the 4pd forum.
    2) Where will I get acquainted with the results of the “training”?
    3) The weather is incorrect, change the provider for russia.

    Firmware bracelet:
    1) The most important thing for a fitness bracelet is the precise operation of the sensors that the F4 can not do at all. Pulse even during exercise does not rise above 90, the pressure is almost always as in the resting mode, and does not measure automatically, you can not set the intervals as with the pulse (including in the training mode).
    2) It is very important to change the Russian font “Cyrillic alphabet”, the letters should be more compact and the distance between them is smaller, approximately like the Angian font. Notifications can not be read at this time, even a couple of words do not hold onto the keran.
    3) It is necessary to make a notification about a low charge. For example, with a charge of 15-20%, a warning was given to ekaren with vibration. At the moment, a quarter of the scale can be drawn on the battery, and the bracelet is switched off without warning.
    4) Change the date format on the dials by mask: day-month-year.
    5) Add new dials. Large time + date + distance traveled.

      About the translation, thanks for your suggestion. We can’t change all the translation, but I asked the 4pda forum friend to help us translate the F5 user manual. It will much better than the previous. 🙂

      About the training result, you can go to the history to check it. OK, it seems that the weather doesn’t work for Russian users. 😐
      And thanks for your suggestions, I’ll translate them and send to our engineers. 🙂

    Hello, how is possible that you have released the F4 for sale before that the firmware and software was OK? Some update for fix bug are ok but you release update with many bugs. I have a F1 and work better than F4. I have asked to the seller a refund but isn’ t possible because for they isn’t a defected product. I think isn’t correct that we have bought a product that not work well. Is there a planning for release a firmware and a software that solve all issues of F4?

    – running 48 minutes with bracelet -> activity stopped itself after 35 minutes, when sleeve get wet from sweat
    – swimming 1 hour -> activity stopped itself after 41 minutes (water contact interacted)
    In both cases I did not touch bracelets display/touch-key.

      Hello Stefan, thanks for your feedback. I’m afraid that we can’t do nothing, once we received such reports after F4 released, we created many firmware, did many test to solve this issue. But as the limitation of one touch-key, there is no way to lock the screen while you running or swimming. What we can do is to reduce the sensitivity of the touch key. And increase the click times when you try to stop the sport. Anyway we’ll keep on working, do more test to improve it.

        Why don’t you try to make a lock mode as in the player. Example 5 single taps will block the action of the sensor until again will not be made 5 single taps. After that, the lock is released and the sensor works again in normal mode. You may have to use a different lock sequence, for example two short presses and one long display of this process on the screen.

    With the new version 0.2.2 the heartrate tracking not work. This function works perfectly with 0.1.8. With upgrades you have to improve and not damage the band.

      Hello Danilo, heart rate tracking? Do you mean the real-time heart rate synchronization in Fundo Pro?

      • Danilo

        Nov th, 2017 3:20 PM Reply

        Yes

        Nov th, 2017 3:36 PM Reply

        Yes with 0.1.8 the real-time heartrate monitoring works very well: I set a time (for example every hour) and the band measures the heartrate during the day automatically, but now I set the time (every hour) but the band doesn’t start. Also the sleep monitor is less accurate then before. Altitude and weather are not accurate: my phone report 109m but the band show 485m and at the same way for weather: my phone show rain but the band show sunny. App version 1.2.4 firmware version 0.2.2

    I would like to know why the version of the application 1.2.4 defines many antiviruses as a virus, even a built-in antivirus does not let you install, you have to use a full copy called techmade.

    My comment the next application is just bad, constantly fails the synchronization, the pedometer works even lying in bed, the heart rate monitor and others takes the data from the air did not know that oxygen has a pulse correct application and the bracelet itself makes sense to sell a raw product?

    My phone reports a virus in your app. I would suggest other users to scan their phones also and provide the results. Any comment from the developers?

    In the graphs there is no information the y-axis. For this it is not clear how many steps completed in each time period. X-axis information is not enough, time stamps are placed too far away, would the difference not 12 hours but at least 3. Information about sleep is not correct, the dream itself is not determined correctly. It is only from 21.00 to 09.00, and in the dream I was credited the time that I was just watching the TV. Need a different algorithm for determining sleep, which gives the correct data on sleep in all day, look in the xiaomi me band, for example.

      Hello Yandex, thanks for your report. 😐 Yes, you are right, the pedometer is not that accurate. About the sleep monitoring, this bracelet doesn’t support something like xiaomi Mi band. Anyway, I’ll tell our engineers about this, hope they can improve it.

        Hello, Jon. I’m talking about displaying graphs in the app, not the accuracy of the pedometer. Try on schedule to understand how many steps passed from 10 to 11 hours and you will understand what I mean.

    Hello. After firmware upgrade (version 0.2.2). Readings Outdoor and Weather give erroneous testimony.

    The bracelet began to turn on spontaneously (wave of the hand) although this function is disabled. Steps are considered at any stroke, even in a sitting position. The pressure reading counts the shots without stopping (do one-time check).

    • Jon

      Nov th, 2017 3:16 PM Reply

      Hello Fobos68, about the pressure issue, we also received some reports about this. Our engineers will take on it. But about the pressure reading, you know F4 receives the data from your phone, if you did not pressure the update button, it won’t update automatically. The pedometer will count on when you move your hands, it is OK, because when you are sitting, it only counts a few steps. 🙂 I suspect that the bracelet gets a wrong positioning, that’s why the weather and altitude is wrong. Did you turn on the GPS on your phone and update it? Maybe it works.

        Hello Jon, the app ver is 1.2.4. I’m from Athens, Greece. Phone model is f4 v.0.1.8. I also noticed that not all notifications are showing. Per example i just got 5 emails and only 3 of them showed on the phone screen. Also altitude, pressure they don’t seem to work. I assume it is the same problem as weather data? Thanks in advance for your help.
