Storing Bitcoins on an offline Android smartphone

I have a spare smartphone that runs on Android 9.

Will it be safe to store Bitcoins on it by following the below steps:

  1. Format the phone

  2. Install nothing but a Self-Custodial Bitcoin wallet app on the phone

  3. Transfer Bitcoins to the wallet

  4. Turn off the internet

  5. Keep the phone switched off until needed.
