Please note that the impossibility to install an app when the dimmer is active is NOT a bug. It's the Android OS that forbids to do potentially dangerous things when an app uses an overlay over other applications (because overlays are also used to send taps and other messages to the system  and could install malwares or unwanted apps without the consent of the user). All similar apps have the same problem  and it is not fair to give only one star if the programmer is not responsible of that """"""""""""""""feature"""""""""""""""". IMO  Dimmer is excellent  and should be rated 5 stars.""
