1. Location access

For the app CamSam/Blitzer.de (PLUS) to give you precise speedcam and danger alerts, it must know exactly where you are. You need to allow it to access your phone’s location. This is how you can best adjust the location services…

First, you need to check if you’ve allowed Blitzer.de/CamSam (PLUS) to access your location.

Go to Settings > Apps & Notifications > Apps > Blitzer.de/CamSam (PLUS) > Permissions. Here you need to at least give permission to access Location.

If you don’t have the Huawei P20 PRO, your settings might look a bit different. We’ll gladly assist you with the settings on your smartphone. Just send us an email to support@camsam.com.

2. Turn on GPS

The location services should be switched ON in general. Our device is Huawei P20 PRO.

Go to Settings > Security & privacy & Location access > Access my location ON

go to top

3. High accuracy

For your position to be determined as precisely as possible, the location mode on devices up until Android 9 should be set to „High accuracy“.

For smartphones with Android 8: Go to Settings > Connections > Location > Locating method > High accuracy. Our example shows the Samsung Galaxy S9+.

For smartphones with Android 9: Go to settings > Biometrics and security > Location > Improve accuracy > Wi-Fi scanning/Bluetooth scanning ON.

4. Huawei: Additional settings

In case your GPS reception isn’t stable on your Huawei-Smartphone, please set a checkmark within the app settings in General > Use Google Location Services.

5. Xiaomi: Additional settings

If the widget cannot determine your position, you have to except it from the energy saving modes of your smartphone. Example:

6. Energy saving modes and GPS reception

In order to work properly, our app needs access to your phone’s location services, the internet and the phone memory, among others. If you’ve restricted the access, in some cases it won’t work corretly. One of these restrictions might be the energy saving mode. This might prohibit the app from accessing the location services in the background. Please make sure you don’t have any restrictions active. In the following are examples of two different smartphones to show you how these settings that need be changed might be called. The exact names might vary from one phone to another. Our app should not be „optimized“ by your smartphone.

Ex. 1: Google Pixel 3a, Android 10: Go to Settings > Apps and notifications > Advanced > Special app access > Battery optimisation > Not optimised > All apps > Blitzer.de/CamSam (PLUS) > Don’t optimise

manually

Ex. 2: Huawei P20 PRO, Android 9.0: Go to Settings > Battery > App launch > > CamSam/Blitzer.de (PLUS) should NOT be Managed automatically but „Manually“.

special_access

Ex. 3: Huawei P20 PRO, Android 8.0: Also, go to Settings > Apps > Three dots > Special access > Battery optimization > All apps > Blitzer.de/CamSam PLUS > Don’t allow. Only this way you can make sure that the app isn’t negatively influenced by optimizations.

unmonitored_apps
Ex. 4: Samsung Galaxy S8, Android 8.0:
Please go to Settings > Device Maintenance > Battery > Unmonitored apps and please add our app in case it’s not yet listed there.Since the setting can be called differently from phone to phone, here’s another example from another phone.

protected_apps
Ex. 5: Honor 7, Android 6.0
Settings > Advanced settings > Battery manager > Protected apps and add our app there.

7. Position of the smartphone inside the car

We recommend you to try various positions to find the optimal one inside your car. You can try placing it directly in front of the windshield or on the air vent. You’ll obtain the best result placing the smartphone where it has the clearest view of the sky.
E.g. metallized windscreens, front cover heaters or thick, noise-reducing windscreens might not allow for a good GPS reception. In these cases you should consider placing your smartphone in the center console.

8. Check of location services and GPS receiver

This is how you can test your GPS receiver:
Download a free app with which you can determine your precise GPS location. It helps if the app also shows the number of satellites in sight.
Our recommendations for apps:
Android: GPS Test, GPS Status & Toolbox, …

Please open GPS Status while driving and place CamSam/Blitzer.de PLUS in widget mode on top of it or in background. Make at least 3 screenshots of the GPS Status app at different times – but especially when our app alerts you of the GPS loss. The app and the screenshots will show if your GPS position can be determined precisely enough for our app to work properly.

If you need any help, please send us your screenshots to info@blitzer.de.

Together we can find the cause for the GPS loss and maybe help you in fixing it.

9. Further help for GPS problems

Sometimes it’s very easy to fix GPS problems. Try the following:
a) Switch off the phone entirely for several minutes.
b) Switch it back on.
c) Remove the smartphone case, if you’re using one.
d) Check again, using a GPS status app, if your position can be determined now.

If your position still cannot be found, the GPS antenna might simply be defective. In this case you should send the screenshots from GPS status to the Smartphone manufacturer.
