Good app, if people are saying that it's inaccurate, then their phones may have OTG support in their software because they are running Android KitKat, lollipop, marshmallow, nougat, Oreo or pie, but the processor is not powerful enough to supply the power from the battery to the device and receive commands from the device.

Fast and accurate. This is a great app. Now that I know I have OTG support, I will keep looking for a better file manager to make file copies and transfers.

Very good app. However, it unfortunately found that my phone does not have the OTG function so I bought a scoping camera I will not get to use. Bummer. Oh well, at least now I know.
