1. I want to change my review on this app, every time I go to clean my junk files, it always says that there is 1.9gb, not once in awhile, almost every time, which makes me question about how good this app really is, at first I thought it was great, but after using it for a couple weeks, and seeing the same junk numbers time after time, I don't believe it's doing what it claims to do, I'll find a different app and delete this one, I know I don't have 1.9gb every time I clean.Nice application fast cleaner, The phone master application is a bit like the river, moreover it can be used in a very nice way, it is actually better with a little more update in the design.
