I agree about the adverts on DS & FS. I force quit DS when an ad pops up; I refuse to watch ads just to Play when I am a paying customer! If they start that here, my wallet closes permanently.
Re: constant resets...do you have Background Refresh enabled on a lot of your device apps? They will crash & burn your RAM for sure! (especially Mail IMO, I just Push a few times a day instead of letting the Mail app monopolize my RAM & bandwidth)
