I found something that excites me to no end until I can get root.
Sprint has a nasty habit of putting its name where the notification icons sit on the left upper side of the screen. I hate this because if my screen comes on that's where I look to check my nots. if there aren't any I see Sprint, which is advertising for them, and I do so hate that. no free advertising from me or ads to me. I choose what and when.
what I noticed is that with the notifications from my any.do app, using Cal add-on, it blocks Sprint as long as I let the notification sit there. whew. I can leave one active no problem, if that's all it takes. when I tap my screen Sprint comes back only briefly and then is gone again. so much better.
