This app sucks the donkeys nuts, one star is an exaggerating lie, zero would be too high. It literally tells you what you already know, the way they make it sound when you read their "synopsis" if you will, it'll tell you the problems you might have with the OTG capability you already know you have...as well as a couple of other things you'll find if you pay any tiny amount of attention to your phone...and don't get me started on the so called "advanced" features.......it's bad enough they make

Cannot connect to OTG. Not sure why. Before this my phone can connect auto without apps. Already check setting n all still no change. Try using apps too like this one still nothing.😌

★☆☆☆☆ Justin H · Apr 6, 2025

Forced me to rate the app the very first time after I installed it and opened it, then nothing but ads until you can actually hit the buttons to do something with it and then there are more ads. Uninstalled.
