+ + + + Useless

+ You can see the application of the same signature.
Also the name of a different app developer, you can check the actual app but signed with the same key.
Will be making a decision when I thought "...? Maybe the same two apps, the author actually." (This is a reference level, because there is a possibility to sign with another key)

+ You can see the extent of the impact of sharedUserId and signature permission.
sharedUserId information and signature permission can not be confirmed because the apps installed on the screen, which we or painful app whether you are linked and how to check app.
Decided that you need to make sure AndroidManifest utilization is real, in a simple "What a group using the same signature application B and application A is" app "D app and C is" Do What shareUserId same thing you can.
