Why not use mycelium? The whole point of using electrum on android was that it was the first wallet working on android to have deterministically derived keys. Mycelium added that and is currently probably the most popular android wallet - I see no reason not to use it instead of electrum.
i am agree with you, since i dont use electrum. even i am new with mycelium, but i suggest you use mycelium, the dev do update in some regular time, last update if i am not wrong is last week or soo, i am sorry i do not remember.
