I have written down on a piece of paper 12 recovery words for application, but I do not have the first 3 words
So you have written down twelve words yet you're missing three?
Was it damaged to the point that it's unrecognizable or are thinking that 'Coinbase Wallet' app has 15 words?
If the former, I second the the replies above.
If the latter, Coinbase Wallet only has 12 words and it should work for recovery.
I have a little problem, I have a coinbase wallet on my android phone. My son on the computer turned wipe option on my smartphone from the Google account.
Speaking of Google Account, your wallet has an option to backup the seed phrase encrypted into your Google account.
And AFAIK, only your device was wiped out by your son, have you backed it up using that option?
If yes, there's a recovery option for that backup: "
Restore from Google Drive".
