# ❓Why do I get the 'Step sensor not found' Error?

On a number of **Android** devices, Walken may fail to launch because of the 'Step sensor not found' error.

In this case, the device you are trying to launch Walken on apparantly **doesn’t have a step sensor** and therefore can not provide proper operation of the Walken app. Unfortunately, Walken will not be launched on such a device.<br>

**Steps data** plays an important role for the Walken gameplay and features, thus accurate and reliable step count tracking and sync is key. On **Android** devices, having a **step sensor** is necessary to launch and use the app. Walken does not rely on an **accelerometer** to count steps because of a number of reasons, mainly because it is *inaccurate* in terms of step tracking.

**To solve this problem, we recommend:**

\- Use another smartphone that has a step sensor (make sure to check the specifications of the device);

The Walken team is working to add **wearables support**. Once it's implemented, it will be possible to launch the app on devices that do not have a step sensor.
