I was hoping this was going to help me keep my phone clear of problems but the more I used it the worse my phone got. I ended up with a phone with apps in a deep sleep that I was unable to reverse. Only way to get support was to pay nearly $20 which I thought was ridiculous. It seemed likeanother every time I ran across a problem they wanted more money. I wish I'd checked reviews before purchasing. It did nothing but screw up my whole phone.
