If you're seeing strange artifacts on your RepOne Sensor screen, including erroneous pixels during startup, lines of pixels, a screen full of white fuzz, or upside-down text, these are semi-normal and are due to issues on our I2C communication bus between the screen and the computer in RepOne Sensor. These issues do not impact functionality and are purely cosmetic, and most of them will be fixed in the upcoming firmware update v0.6.X.
Most of the above issues are related to low battery. If you see upside-down text or a screen full of white fuzz, it's time to plug your RepOne Sensor in to charge. We know this is a blunt way to notify you of low battery, this is being addressed in the upcoming firmware update as well.
