I need a little help please. I reset my phone to factory default. I installed the app Gun Bros but didn't like it so I uninstalled it. When i checked my internal memory via task manager it seems that the files from internal memory haven't been deleted even though I uninstalled it. Is there an app that permanently removes the app from internal memory?? I even did the "clear data/cache" and still shows like 40mb used any help plz?
