i am using #Osmand for #navigation. the #f-droid version. i was so lucky with it, a long while it ran great on my old #samsung#galaxy#s5 on #lineageOS but now the crashes are back and its unusable again which it was several (partly very long) periods in the past. i don't know what they are doing that its such a pain in the ass; maybe they have problems to do a good memory management. i am very sad, because i love that app and its plugins. it nearly is able to do everything you would like to do with such an app. when it runs. now i'll try it with #organicmaps. seems to be spartan but stable. and it has no trackers. if you have any further ideas, you are welcome.
I'm currently playing around with a couple new #Mifare NFC tags I bought. The only bad thing is that NFC is not really supported by /e/ OS on the #Fairphone 3 and the Samsung #S5.
