.apk Files or Third-Party Applications
Your device is not able to read .apk files, which are files that contain Android-based applications for use on Android-based mobile operating systems. Loading a third-party app to an Android device using one of these files is commonly known as "sideloading."
If the device is not working properly and an .apk file has been sideloaded to it, you can uninstall the file.
- Press and hold the app icon
- Select App info
- Select Uninstall
If the issue continues, a factory data reset of the device can be completed to remove the files. Performing a factory data reset will reset the device to factory default settings and delete any saved waypoints, downloaded apps, music, photos, videos, and other data. A factory data reset will also remove profile information for the compatible devices.
Before performing a factory data reset, your tracks, route, and waypoints can be synced to the Garmin Explore Library if the device is paired with the Tread® App. To pair with the Tread app see Installing and Pairing the Tread App.
To Perform a Factory Data Reset:
- Open the device's Settings menu
- Touch Personal
- Touch Device Reset
- Touch Erase all data (factory reset)
- Touch OK
- Touch Reset Device or Delete all data
- Touch Reset Device or Delete all data again
The device will restart and prompt you to set up the device again. Note that the device can take longer to start up for the first time after it has been reset in this fashion.
