It won't be long before they can take your phone from you during a traffic stop and see if you have a Bitcoin wallet on your phone. If you do they will then confiscate your phone and you will have to prove your Bitcoins are innocent (and your phone is innocent) before they will consider giving your phone and Bitcoin wallet back to you.
This is why we will keep only an operating balance in a phone wallet.
The main balance will be a colder storage at home in a vault, or in safety deposit box. You will periodically move funds between your hot mobile wallet and your cold storage.
Btw, it really sucks what happened to you. Charge it to experience!
