Well I started doing the process of elimination and decided to compile a default blank Tab5 project in UiFlow v2.3.1 with no unit sensors and the i2c driver install error still occurred... See screen shots... So something else is trying to load the i2c drivers in UiFlow v2.3.1 for the Tab5 device and is having a problem installing it...
Question: Could this be a possible bug somewhere when it comes to Tab5 and the UiFlow IDE???
