It looks like when running/walking in the dark the Venu 4 seems much dimmer. The Venu 3 did not do this. With the various watchfaces the items like floors climbed in a smaller circle along with the othe items are hard to see. Please let us keep it bright in low light and adjust for full light. Also, I too have issues with the brightness being too dim in low light. It’s always just fine in bright light. I always keep the brightness level set to max because of this, which is a shame because it doesn’t need to be that bright other times and chews up a lot of extra battery.
