First - Do you think Light Flow is safe? I like the app but there is that scary message you get when installing it on T-bolt that says it can monitor key-presses. Second - As far as I can see all of the LTE Toggle Apps are about the same. Trouble is I have no idea what the other 3 settings mean (besides the LTE on setting. Is there an LTE Toggle app that drops the phone down to 3G automatically whenever the screen is off and then automatically reconnects to LTE when the screen is on?? That is really all I would like it to do. I used to like that power bar on the Droid 1 that allowed you to shut off 3G entirely with one button press and back on with one button press. Give me 4 choices and I'm baffled.
