[Taler] Tales wallet 0.12.0 does not start (android)

[Jürgen Beger]

Hi,
a friend, who is installing the Taler Server, wrote me, that his 
smartphone titeled the wallet APP as "Malware" ???
When I start the Taler App (Version 0.12.0 installed from f-droid) with 
my fairphone with /e/OS the APP does not start.
The old nightly version 0.11.0 (07.06.24) works.
:-(
Best regards
Jürgen
