Use wallets like myceilum? They offer a cold storage spending option. Make sure your BIP38 passphrase is long enough and give one to your TRUSTED friend. If you happen to lose it, you can get it from your friend. 
I'll stay away from phone wallets - I seem to hear about them having holes and attack vectors every other day. In the case of myself - I'm pretty happy with my set up of an air gapped computer running Electrum and a main computer connected to the internet to create txs from. And an encrypted version of the seed stored on paper and an encrypted version of the wallet on various USBs/personal dropbox with 2FA. It'd take a lot to get through that and steal my coins
