What SD card reader or OTG device and/or what app are you guys using to view your trail cam pictures in the field? Nothing, no combo has worked for me yet. Android phone by the way.
My WGI SD card reader has worked great for 5 or 6 years now.
But I also have a system where all my cards are labeled and I just keep switching the same 2 cards out for all my non-cell cams then check them all on computer if I don't use the card reader.
