I used to connect my OTG USB drive and/or a USB mouse, but now nothing OTG works anymore. Any chance there was an update that broke it, or maybe some other app that I installed? Any ideas? NOTES: the OTG USB flash drive still works with my Windows computer (ran chkdsk and no errors found). It also still works with other Android phones and tablets of different makes/models. The OTG cable/adapter still works with other Androids, and so does the mouses that I'm testing with.
