For the most part, since holding down water and being able to jump at the same time makes it really fast to play the game, even modern versions of CAL are probably faster than android. Also to note, you can't downpatch the game to readd the glitches that are essential to the WR, such as spike climbing, so that puts Android at an even further disadvantage.
There may be further glitches that make Android faster, but I don't know of them, since I do not own the android version.
it really shouldn't be slower just harder IF you're running on the new version but (as far as i know) there is no way to down grade the android version which makes it slower
There actually is, if you find on the archive the old version and delete the new one, you'll keep the old one. You don't need to update it when prompted
