I've also lost quite much money to scams, sending to wrong addresses etc.

Last time had a guy wanting to buy bitcoin from me, he had registered an account at some exchange with the name thebtcmarket.com, but needed help for everything, including recommendations for exchanges and finding the deposit address at the exchange. I was in a hurry, should probably have been more careful ... just after sending the funds I realized the address was used before. I decided to try to register my own account there, and got up exactly the same deposit address. Luckily it was a relatively small amount, but still I find it incredibly annoying.

I do have a freewallet app on my android with 1 XMR in it, I should try to move it out from there.
