Maybe it is just my device, but with 10.2.1.1055 on my Z30 (STA100-3) I can no longer use USB OTG. When I first got my Z30 it worked fine, I installed 10.2.1.1055 and it no longer recognizes the flash drive. Has anyone else run into this? I am installing 10.2.0.1803 to see if that works better, but I cannot go back to stock because Link is acting stupid.
