Hello, I have an HTC Sensation Vodafone edition I know that similar topics have been posted on this forum, yet they were all relating to rooted devices and my device is not rooted. I had previously installed whatsapp yet when I tried to update it it said that my phone had insufficient storage ( I have 300mb free on the internal memory and 500 mb on the sd card). So I tried to uninstall it and now I can not reinstall it, as it says that my phone has insufficient storage. I have tried clearing the updates, cache and data from the play store and this has not helped. I have also tried installing the app from the .APK file and I get the same error message. Does anyone know of anything I can do appart from Factory resetting my phone? Any advice would be appreciated.
