Describe the bug

Not able to send any assets with Keystone hardware wallet account. Getting error on confirm screen. This seems to be Keystone hardware wallet specific. I am not able to reproduce with Ledger.
When I retry this scenario on a non-hw wallet account I am either able to send or if low on asset balance for cost of transaction then an error is shown indicating insufficient funds for gas * price + value, which seems to be proper handling.
Similar error occurs for iOS

• Was able to successfully reproduce on v7.19.0. Issue was introduced in v7.19.0.
• Was not able to reproduce on v7.18.0.

Android

iOS

Expected behavior

• Previous mobile app versions would prevent users getting pass the Amount screen if there was a zero asset balance by not enabling the Next button.
• Currently if a user is able to get all the way to the Confirm screen we seem to be handling this properly for non-hw accounts.

Same scenarios using wallet account, not a hardware wallet account
