Stop the annoying mobile game ads!?!

Well we have all been there, playing one of the million free mobile games but the nonstop ads popping up every other minute makes this experience far less enjoyable... Well I think I have accidenatly found a way to get rid of them (andoid only as far as I know)! Activate developer's mode on your android - settings -> about phone -> build number and tap tap tap x7 . Then back to settings -> all the way down to Developers options- under apps -> don't keep activities-> on. It worked for me, but it also will disable ability to play optional ads that offer rewards (some games). Hope it works for you guys as well!
