- new interface with rounded on/off buttons
- different size of keyboard (was also available in previous preview)
- integration of Word in email giving more editing options
- choose an app option
Among all the new feature the one that wasn’t heard of, is the choose app feature where you can notice the Removable Disk option which you find in a PC, so this may be showing the way to having support of external storage devices in the future.
Do note that these are just leaked screenshots of some build and not surely the one that will released on Friday. The above feature may or may not be in the build. Do share your comments below and stay tuned for any further info.
