What they failed to mentioned is the microusb port would loose its handy ability to transfer data. I was surprised to see, that after this update I couldn’t use anything on the port anymore with 3 different microusb to full size adapters or OTG cables people call them. It’s now just a port plug for charging only. Real shame, It was good to have the microusb port for my mouse and still have the USB 3 port open for my USB memory stick file transfers.
Was this planned Microsoft? Or is my unit faulty? There has to be a reason for this, was it to improve the charging issues people have been experiencing?
