Cannot browse App documents after upgrading to iOS 8.3 I just upgraded my iPhone 5s to iOS 8.3. I found that I am unable to access the contents of Apps using software like iTools, iFunbox and PhoneView.

Does iOS 8.3 change security settings in App document folders?

Tried software:


iFunbox
iTools (latest version &amp; version 2013)
PhoneView (demo version)
iMazing (trial version)
iExplorer (trial version)




UPDATE Here is the security content change log of iOS 8.3 regarding the document access (CVE-2015-1087):

  CVE-2015-1087 : TaiG Jailbreak Team
According to Macrumors:

"Apple has changed security settings in iOS 8.3 that prevent file managers and transfer utilities such as iFunBox, iTools, iExplorer, iBackupBot and PhoneView from gaining access to app directories on an iPhone, iPad or iPod touch. 

The change breaks current versions of transfer utilities for OS X and Windows, forcing many developers to release new versions of their software with workarounds that restore at least partial sandbox access."
