Hello, I have created an application. When a screen opens, a timer starts allowing in a label to enter the lattitude and the longitude. However, I just realized that they appear every second between cut by “undefined”. Where can this come from ??? I do not understand ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/b/9/b9f054ed4d243f322d4247e22ee247af6bc78178.png) ---

I wish I could make the latitude and longitude change instantly and permanently in defined labels. ---

There was an issue with location sensor which was resolved but might need that you apply other settings. See this post > [@Location Sensor Unable to retrieve location with cellular data](https://community.thunkable.com/t/location-sensor-unable-to-retrieve-location-with-cellular-data/1482946/14): > > Hi there, Unfortunately, this seems to be an issue with Expo, who provide the framework we use to build apps.  You can see discussion of this behavior on Expo’s Github [here](https://github.com/expo/expo/issues/14248).  Thunkable team member Jose has deployed a partial fix.  Depending on your version of Android, you may need to set EnableHighAccuracy to false for Location Sensor to work as expected on your device. I use Android 11 and I don’t need to do this, but Jose reports needing to do this for Location Sensor to work on A… ---

perfect thank you. How can I make this happen automatically without having to click a button (the latitude and longitude change automatically every second). I was using timer, is this correct? ---

> [@team.eps.numeriqueg](#): > > I was using timer, is this correct? Yes that is correct. Just remember to update the two labels inside the `GetCurrentLocation` block and always test for errors. If the sensor is busy or was not fast enough to respond, it will give an error and both latitude and longitude will become `undefined`. **[Edit]** I updated my project and the code works will with the `Timer`.

Hello again, it looks like everything is working fine. However, I wonder if all devices find the same locations? Or close? Because it seems that my phone is often undecided on the location: up to 0.002 difference in latitude (quite a few meters anyway) and longitude from one second to the next. ---

Try playing with the `High Accuracy` option in the `Location Sensor` setting page. ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/5/6/56d383859cb1b8b394d5cab30f316d93963e876c.png) ---

Unfortunately not enough information on the download issue to give any suggestion. Are all students download the same single copy received by email or each student has own account and has separate email and download link? It is worth remembering that download link are only valid for 24 hours. [Next page](https://community.thunkable.com/t/location-sensor-undefined/1517835.md?page=2)
