While I will continue to receive small transaction amount (from faucet or small investment) I think I will be in the same situation after few month.
Can I do the same process once every couple of month?
Do you have a android wallet (better if sync with desktop) that are not creating so many byte for receiving all the "dust" that I will continue to receive and has manual transaction fee option?
ALL bitcoin wallets will do this... it is just the way bitcoin works. Either stop collecting such small amounts, or live with the fact that you're going to end up with large transactions.
The only way to stop this is to not receive small amounts.
