A new version 7.4.1 has been released for LK8000 and LK8000 Beta. Both files were downloaded from the Google PlayStore and subsequently installed on my Samsung S21 FE.
LK8000 was installed first: Internal Storage/ Android/ data/ org.lk8000.beta/ files/
then LK8000 Beta was installed: Internal Storage/ Android/ data/ org.lk8000.test/ files/
The data files (such as airspace and waypoint) that I placed in LK8000 were also apparently (automatically) placed in the same folders in LK8000 Beta.
Is the installation on my Samsung correct and why are these confusing path names used?
Because a year or two ago Android said it had to be done that way. Do they both work OK, if they do then it is correct. You don't need both, if you always want the latest, use the beta, and update when something new comes out, if not use the stable version.
