If you had the experience of buying miota on bitfinex and trying to withdraw to iota wallet on android you will notice that it always says wrong address. I saw in many forums others were having this problem, i didn find a solution for android wallet but i installed the windows version of the light wallet and it worked, i could transfer my iotas to my windows wallet , so i recomend you guys to do the same and not leave it on the exchange.
If you have any doubs about withdrawing iotas to the windows wallet ask me and i will help you
