I think you have to make a good passwords. and you need extra security fow your wallet.
I guess based on my understanding about wallets, you could enter a same account in the same wallet on your phone. And you could enter the same wallet in your cellphone. Maybe you could try to have other wallets so that not all of your btc wilk get lost because of being stored within one only wallet. And to be able to open such wallet you need to inout passwords.
