Another argument is that a burglar is unlikely to expect you to use a smartphone for a cold storage. If he sees a phone to steal, the steps he'll do later are pretty much known. Reset, and sold to some stranger for a ridiculously low price.

This can be a good point indeed: basically hiding the cold storage in plain sight.

Also, as said, you can use a password to encrypt everything.

True, this part I forgot about.

The best argument for not using a smartphone as cold storage, is that desktop wallet software such as Bitcoin Core and Electrum are simply more tested, and are consisted of a bigger community. Another good argument, is that a linux distro is far more tested than a smartphone OS.

This is a good argument. Still, this doesn't make the cold storage unsafe per se, especially since the wallet seed has backups.
