                        // Before Q we represented some runtime permissions as install permissions,
                        // in Q we cannot do this anymore. Hence upgrade them all.
                        grant = GRANT_UPGRADE;
                    } else {
                        // For modern apps keep runtime permissions unchanged.

                } else if (bp.isSignature()) {
                    // For all apps signature permissions are install time ones.
                    allowedSig = grantSignaturePermission(perm, pkg, ps, bp, origPermissions);
                    if (allowedSig) {
                        grant = GRANT_INSTALL;
