I upgraded to Windows 10 Mobile using the Upgrade Advisor tool for my Lumia 640 XL.
Current Build : 10.0.10586.318 Version : 1511
My phone memory is completely used up. When I look at storage the size of the applications is huge. Mail and Calendar uses 1.57 GB of space Rest all are around 50-100 MB.
When I installed these apps the size was not this big. I understand the data being generated but is there a possibility of removing only app data (as in Android) or is reset the only option.
