I have installed the F-droid repository on my mobile phone and I have been using it for a while. Then, while checking the settings menu, in the section “My apps/ Manage installed apps”, I found something weird: there is a bunch of apps I haven’t installed that share this two elements:
These apps don’t have the usual buttons “Run” and “Uninstall”.
The version of these apps gives the message “Different signature to installed version”
I attach two screenshots of the F-droid app that show in a clear way what I am trying to describe.
Thank you very much for your help!
