I am using Tasker to stop data when the screen is off and enable it when it is on.. Sometimes I have issues with not being able to turn the data on quick enough, etc.. But lately I am having major issues with the 4G LTE flashing one of the single arrows or no arrows for data connection. While in either of these states, I cannot do anything over the mobile network. It appears I can only use the mobile network when both arrows are lit up. Does anyone know what might be causing this issue of not lighting up both arrows? Does anyone know what each arrow means(if anything)? Thanks in advance!
