Several users complained on the Github page of the app called “Vigilante” for not being able to remove the app once it was installed.
The creator is not helpful at all and very unfriendly to everybody who reports this issue (https://github.com/FunkyMuse/Vigilante/issues/150).
He says it is the fault of “buggy” F-Droid. Later he admitted it occurs on few phones only and it is the fault of them (https://github.com/FunkyMuse/Vigilante/issues/122).
He closes all complaints even though they couldn’t be solved. I myself waited for several updates, but still the app cannot be uninstalled via F-Droid or Android app menu.
This app is quite suspicious for staying in the system forever without any way to be removed.
Is it really an issue of F-Droid? Thanks for any help!
