The nonsense of the translations of terms such as Google Maps or Yandex Maps I had already dealt with previously, it is true that perhaps in Greek there is a sense .... but everyone can decide as they wish.

I confirm that as regards SamCam the link is correctly set for the PLUS version.
To make the free version work you have to replace the link in the "buttons_start_external.ui" reducing it to "com.camsam" instead of "com.camsam.plus".

Traffic Bans (FlexSoft) is an apk that I found on Apkpure. The button link works fine. From a first glance it seems that it proposes the timetables for the transit of heavy vehicles on the highways of the various countries.

Both of these apps only work in portrait

As for TT Speedcam, the address associated with the button corresponds exactly to the package name of AMIGO ("com.tomtom.speedcams.android.map"), for what opens to you...

I shot you PM
