I can't really speak for android, but I experienced very "long loading" issues while I save often and especially during dialogues.. one dialogue with Charlene Miller even causes the save corruption, so be aware of that... when I started a new game and was saving very little and definitely not during the dialogues, my saving issue was all gone.. I played the entire game and my saves was loaded in a moment.. so try to not saving during dialogues and also try to not saving after every single scene and you probably will be ok..
