[member_13579]

My Yoga Tablet 8 (Lenovo B6000-H) is not working USB OTG. But I go to Settings>Storage, I see the Mount USB storage.
Help me for these situation.
I need it because my flash drive is stocked.

-This situation is happened after factory reset-

Try your USB OTG in another device to see if it is faulty.
