Case 1:

• Affected by contract deploy event. It takes more fee than usual transfer

• Try some rcm: https://github.com/ton-org/ton/issues/23#issuecomment-1963723559

Solution for transfer all:

• [x] Improve estimate fee value:
• [x] Improve transfer all action:
• Actual: Manually calculate the maximum transfer amount and set it to the transaction amount (this might not exactly transfer all because the fee cannot estimate exactly 100%).
• Expect: Transfer all remaining balance
