Hello all. Good day. I am not sure if this has been brought up on a different thread before, kindly merge if this is a duplicate. However, do some of you use battery doctor or any app in cleaning junk files on your iPhone on iOS9? I noticed this when I updated to iOS9, battery doctor's clear junk feature doesn't work on my phone anymore. It doesn't clean junk files from Facebook, Instagram and other related apps. Instead, I just uninstall and reinstall these apps (which I find tedious as I need to download them again) to clear junk/temporary files. Do you also encounter the same issue? Or can you suggest a different app which cleans junk files on iOS 9 aside from Battery Doctor? Thank you and have a nice day.
