                            || upgradedActivityRecognitionPermission != null) {
                        // 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.
                        // grant = GRANT_RUNTIME;

                    if (allowedSig) {
