I have a Samsung tab 4, running android 4.4.2. I want to use My Files to open a file in the app that handles it. Sometimes when I tap the file it opens the file in the app. This is what I want, other times it selects the files (check box) and allows me to rensme, deletw, etc., but not OPEN it in the app!
I don't understand how to control this behavior so I get the result I want. Double tap? No. Touch and hold? No.
How do I control the resulting action to get the file to open when I want it to?
