• If your App’s version number is 1.1. you are all set with the new App.
• If your App’s version number is 1.0 , please update ACT Head Impact Tracker App by deleting the old App on your mobile phone, and installing the new from the Google Play Store. When the new App version is installed, switch the mobile phone off and back on. ACT Head Impact Tracker is using phone’s Bluetooth® wireless communication and sometimes this action is needed for the App to work as intended.

Have you experienced problems with your ACT Head Impact Tracker system during last couple of months?
The latest updates and changes on the multiple mobile devices with Android operating system have been nothing short of significant. These changes may have had critical impact to ACT Head Impact Tracker system connectivity, to be more precise: the head sensors have been unable to connect to the mobile phones and impact information has not been transmitted. These changes took gradually place in conjunction with Android operating system 11 and 12 launches. As a result, ACT Head Impact Tracker system has sometimes not functioned as intended, even not functioned at all in some mobile phones. This is why we made the App update.
We apologize the inconvenience to our Users.

The biggest changes with new App:

1. All Android phone brands (models) do not work, or do not work as intended with ACT Head Impact Tracker. Even if they have Android 9 operating system, or newer.

This listing and functionality is the status as of today. The mobile phone models, electronic components used in them, and operating systems they use are in constant change. We are working hard to keep up with the changes, improve the situation and do our best to update this list in our FAQ on our website, www.act-tracker.com/pages/faq.
We  sincerely apologize the inconvenience the changes and updates cause to our users.

2. Bug fixes and improvements in the new App
A.) The impact time stamps are no longer affected by switching off the head sensor. Please do note: Always empty the sensor’s memory before changing the battery, or the time stamps will not be accurate.
B.) Dynamic Profile listing. The latest impacted profile will be featuring on top of the landing page’s profile listing.
C.) The graphical illustration of the g-force measurement includes only 3ms buffer memory and hence features more impact related measurement data.

Tips and tricks how to improve the functionality:

Samsung
Issues recorded and tips to solve them:
1. Persisting notifications on location or Bluetooth© wireless communication being disabled.
When you install the new ACT Head Impact Tracker App 1.1., you must give it permission to track the location, or Bluetooth© wireless communication will not function. Also, as before, Bluetooth© wireless connection has to be enabled when you are using head sensors. If you “enable” location and/or Bluetooth© wireless connection, but the notification(s) regarding stay on the landing page, close the App and open it again. This should remove already acted upon notification(s).
2. Some impacts do not show in the App.
A.) Ensure you have solid Wi-Fi connection, or have mobile data enabled and active.
B.) Open ACT Head Impact Tracker App, log in, keep it open and logged in when using with head sensors. Real time impact data delivery may also work when App is not open, or while using another application, but this cannot be granted.
C.) Keep the mobile phone active (i.e. screen lighted, not go to power save mode) on the sideline, when you are using ACT Head Impact Tracker head sensors. To adjust the automatic screen switch off: click “Settings” > “Screen” > “Screen switch off” > choose he longest time available. Real time impact data delivery may also work when the screen is off (on the power save mode), but this cannot be granted.
D.) If you have Android Operating system 12 or newer, ensure you have permission (“Allow”) for ACT Head Impact Tracker App also for “Nearby devices”. Click “Settings” > “Applications” > “ACT” > “Permissions” > “Nearby devices” > “Allow”
E.) Change default setting for battery use: “Settings” > “Applications” > “ACT” > “Battery”> choose “Unrestricted”.
F.) Turn off Bluetooth© wireless communication on your mobile phone and switch it back on again. Time to time the connection is just cut off (no notification to the App regarding) and needs to be reactivated again like this.

– Please note that if your phone&App have multiple head sensors to listen to, and/or the head sensors might be time to time out your mobile phone’s Bluetooth© wireless communication reach (couple of tens of meters in most conditions), the impact data may not transfer real time. If so, the head sensor will save the information to its memory (space for 45 impacts). It is recommended to frequently download saved impacts from each head sensor’s memory by switching the sensor off and back on so that it is in the proximity (within few meters) of the App. Ensure the mobile phone is connected to Wi-Fi or mobile data is enabled and active. Also highly recommended to do this every time before you change the battery.
– You can also use the head sensor(s) without Wi-Fi connection, mobile data or mobile phone with the App close by. If so, the head sensor(s) will not deliver the impacts in real time, but will save the impacts to the memory, and the data can be downloaded from them later. Please note: each head sensor can save up to 45 impacts to it, if this amount is exceeded, the oldest impact data will be deleted to make space for the new impact data. Download impacts from each head sensor’s memory on by one by switching the sensor off and back on so that it is in the proximity (within few meters) of the App. Ensure the mobile phone is connected to Wi-Fi or mobile data is enabled.

Xiaomi
We found these phones to have more frequent connectivity issues than the above brands. Especially when listening to 3 or more head sensors. Hence, we do not recommend using Xiaomi mobile phones with ACT Head Impact Tracker, especially if you are following more than 1-2 sensors with it and wish to have real time impact data delivered.

2.) Difficulties in maintaining the connection to more than 1-2 head sensors at the time
Same tips as above.
3.) Time stamps on impacts saved in head sensor’s memory and transmitted after the head sensor has been switched off were not always fully accurate.
