No. Not anymore. I rely a lot on USB OTG to transfer files between my phone & my USB-stick, and was gutted when an update took that option from my previous HTC.
I haven't got a clue as to how to crack / root my phone, so I ordered the HTC 10. And all was right with the world: I had OTG again!
...until the next (mandatory) update about 2 months in.
Yep, it's f@cked again.
I seriously hate those mandatory updates.
Simple rule: "if it's not broken, then don't fix it......"
