A new Windows 10 for Phones Build 10.0.12531.52 has leaked in screenshots yet again and it is more advanced than the build 12527 reported last by us from WPBench. The screenshots reveal a new and redesigned “Contacts” app, ability to edit Phone’s name on the phone itself (like what we have seen on Windows Phone 8.1 GDR2). There is one more feature that is long-awaited and was confirmed via WinHec PPT. The Windows 10 running devices can work as a host for USB storage devices. So, don’t know whether it will be right to label it as USB OTG, but it works similarly.
